In this paper, the flexural behaviour of M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars are studied and compared with slabs made with steel rebars. The optimum percentage of basalt is 0.3% for 50mm length basalt fibres. Due to high particle packing density in concrete made with basalt fibre micro cracks are prevented due to enhanced fatigue and stress dissipation capacity. Addition of basalt fibres to enhances the energy absorbtion capacity or toughness thereby enhancing the resistance to local damage and spalling. Addition of basalt fibres controlled the crack growth and crack width. Load at first crack of M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars is more than M30 grade conventional concrete slabs made with steel rebars because the with addition of basalt and BFRP bars will make either the interfacial transition zone (ITZ) strong or due to bond strength of concrete slabs made with basalt fibre reinforced polymer rebars. The ultimate strength in M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars is more than conventional concrete slabs made with steel rebars. Deflection at the centre of M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars is almost double than the conventional concrete slabs made with steel rebars. Toughness indices evaluated for M30 grade basalt fibred concrete slabs made with basalt fibre reinforced polymer rebars indicates that basalt fibre and BFRP bars will enhance the energy absorbtion capacity of slabs.

Abstract Basalt fibre is formed from basalt rock when melted at a high temperature making it a non-metallic fibre. Basalt fibre reinforced concrete are good fire resistance, strength and light weight. These properties making it highly advantageous in the future to the construction business. There are many applications of basalt fibre like industrial, bridges, residential and highway etc. Fibres of basalt rock are used to make Basalt fibre, is cheaper and have improved physicomechanical properties which is very similar to the fibre glass and the carbon. They can replace many expensive materials resulting in wide range of applications in the field. The raw materials are available in all countries, making their production very simple. The biggest difficulties of the concrete and cement industry’s can be solved by the usage of basalt fibres. It is also used as composite and in the aerospace, automotive industries and fibre proof textile. Basalt fibres have no hazardous reactions with water or air and are explosion-proof and non-combustible. No chemical reaction will be produced that may damage environment or health when in contact with other chemicals. Reinforced plastics and steel maybe replaced by the basalt base composites. One kg of basalt reinforces equals to 9.6 kg of steel. Differences in compressive strength and split tensile test for concrete with and without basalt fibre by using cubes and cylinders are studied in this paper.

This paper prophesies the stress strain behaviour of M30 grade concrete reinforced with basalt fibres of length 12 mm, 36 mm and 50 mm of amounts 0.4%, 0.4% and 0.3% by volume of concrete respectively. Modulus of elasticity and toughness of M30 grade basalt fibre reinforced concretes are also evaluated. It was found that BFRCC mixes show good resistance to impact and has superior dissipation capacity. The optimal basalt fibre volume fraction is 0.3% and length is 50 mm. For this case, toughness index and energy absorbed at fracture have considerably enhanced. With the volume fraction of basalt fiber exceeding the optimum volume fraction, the mechanical properties of basalt fiber are weakened.

In this research work, the bonding characteristics of plasma treated basalt fibres were analysed by employing the fibre pull-out test. 80 samples were prepared with two different spans of basalt fibres (such as 25 mm and 50 mm) and four levels of embedded length (10, 15, 20 and 25) inside standard M20 grade concrete. Debonding and bonding characteristics of the plasma treated fibres were compared with raw basalt fibres through the fibre pull-out test. The plasma treated and raw basalt fibres were characterised through Field emission scanning electron microscope (FESEM) and Fourier transform infrared (FTIR) analysis. It was observed that confirmation of the presence of hydroxyl groups on the basalt fibre surface was realised through the FTIR test and that there was higher adsorption of concrete particles by the plasma treated basalt fibres through FESEM. The de bonding and fibre pull-out energy of the plasma treated basalt fibres were improved by about 9% and 10% compared with 25 mm and 50 mm raw basalt fibres. From the observation above, it can be stated that the surface modification of basalt fibre may lead to a change in the debonding and pull-out energy level.

Geopolymer materials have several obvious advantages such as energy conservation, emission reduction, and waste reuse, so they can become substitutes for cement materials. In this study, geopolymer mortars made from blast furnace slag and steel slag reinforced by basalt fibre and polyvinyl alcohol (PVA) fibre were prepared to explore the effect on their strength and shrinkage properties. Scanning electron microscopy (SEM) was employed to characterize the reaction mechanism of the geopolymer mortars. The results show that both PVA fibre and basalt fibre can improve the mechanical properties of geopolymer mortars during the late curing period. The geopolymer reinforced by basalt fibre manifested a better toughness. A proper content of PVA fibres and basalt fibres can effectively reduce the drying and autogenous shrinkage of geopolymer mortars. The optimal content of basalt fibres and PVA fibres to reduce the drying shrinkage was 0.4%. The SEM results show that the fibres can effectively alleviate the stress concentration and prevent crack propagation.

Full textAbstract:
Filament-wound composite tubular structures are frequently used in transmission systems, pressure vessels, and sports equipment. In this study, the failure mechanism of composite tubes reinforced with different fibres under low-velocity impact (LVI) and the radial residual compression performance of the impacted composite tubes were investigated. Four fibres, including carbon fiber-T800, carbon fiber-T700, basalt fibre, and glass fibre, were used to fabricate the composite tubes by the winding process. The internal matrix/fibre interface of the composite tubes before the LVI and their failure mechanism after the LVI were investigated by scanning electric microscopy and X-ray micro-computed tomography, respectively. The results showed that the composite tubes mainly fractured through the delamination and fibre breakage damage under the impact of 15 J energy. Delamination and localized fibre breakage occur in the glass fibre-reinforced composite (GFRP) and basalt fibre-reinforced composite (BFRP) tubes when subjected to LVI. While fibre breakage damage occurs globally in the carbon fibre-reinforced composite (CFRP) tubes. The GFRP tube showed the best impact resistance among all the tubes investigated. The basalt fibre-reinforced composite (BFRP) tube exhibited the lowest structural impact resistance. The impact resistance of the CFRP-T700 and CFRP-T800 tube differed slightly. The radial residual compression strength (R-RCS) of the BFRP tube is not sensitive to the impact, while that of the GFRP tube is shown to be highly sensitive to the impact.

This paper presents the results of an experimental program carried out to investigate the effects of Basalt Fibre Reinforced Polymers (BFRP) on some fundamental mechanical properties of concrete. Basalt fibres are formed by heating crushed basalt rocks and funnelling the molten basalt through a spinneret to form basalt filaments. This type of fibres have not been widely used till recently. Two commercially available chopped basalt fibres products with different aspect ratios were investigated, which are dry basalt (GeoTech Fibre) and basalt pre-soaked in an epoxy resin (GeoTech Matrix) .The experimental work included compression tests on 96 cylinders made of multiple batches of concrete with varying amounts of basalt fibre additives of the two mentioned types, along with control batches containing no fibres. Furthermore, flexural tests on 24 prisms were carries out to measure the modulus of rupture, in addition to 30 prisms for average residual strength test. Results of the research indicated that use of basalt fibres has insignificant effects on compressive strength of plain concrete, where the increase in strength did not exceed about 5%. On the other hand, results suggest that the use of basalt fibres may increase the compressive strength of concrete containing fly as up top 40%. The rupture strength was increased also by 8% to 28% depending on mix and fibre types and contents. Finally, there was no clear correlation between the average residual strength and ratios of basalt fibres mixed with the different concrete batches.

Wood composite is weak under heavy loadings, which was improved by reinforcing basalt fibres. In this study, chopped basalt fibres with different lengths (5mm, 10mm, 15mm and 20mm) were mixed with fir sawdust at 2.5%, 5%, 7.5% and 10% weight fractions to produce basalt fiber reinforced fir sawdust panels. The reinforced panels showed improved strength values. A maximum bending strength value of 44.1 MPa was obtained when the mean length of chopped basalt fiber was 15mm and the weight fraction was 2.5%. The tensile strength reached a maximum value of 17.4MPa when the mean length of basalt fiber was 10mm and the weight fraction was 10%. Compared with the unreinforced fir sawdust panel group, the reinforced panel group increased bending strength 60.7% and had a 47.5% increase in tensile strength. These findings demonstrate that basalt fibre has very promising prospects for strength improving.

Basalt mineral fibre, made directly from basalt rock, has good mechanical behavior, superior thermal stability, better chemical durability, good moisture resistance and can easily be recycled when compared to E-glass fibres (borosilicate glass is called ‘E-glass’ or ‘electric al-grade glass’ because of its high electrical resistance) which are traditionally used in structural composites for industrial applications. Industrial adoption of basalt fibre reinforced composites (FRC) is still very low mainly due to inadequate data and lower production volumes leading to higher cost. These reasons constrain the composites industry from seriously considering basalt as a potential alternative to conventional (e.g., E-glass) fibre reinforced composites for different applications. This paper provides a critical review of the state-of-the-art concerning basalt FRC highlighting the increasing trend in research and publications related to basalt composites. The paper also provides information regarding physico-chemical, and mechanical properties of basalt fibres, some initial Life cycle assessment inventory data is also included, and reviews common industrial applications of basalt fibre composites.

AbstractThis paper depends on a test examination on basalt fibres which started from volcanic shakes and were dissolved at high temperatures. These stones were accessible from the world’s profound hull. M30 evaluation of concrete was structured according to is 10262:2009 with basalt fibres. The fibres alongside mineral admixtures were utilized in three distinct extents, that is 0 %, 1 %, 2 %, 3 % by heaviness of cement. The goal was to decide the characteristics of fibre reinforced concrete with various fibre extents. The strength properties, for example, compressive strength, split tensile strength, flexural strength, shear strength and the impact on strength of concrete when it was unprotected to sulphate attack after stipulated extended ages of curing were contemplated and thought about. From the examination, it was discovered that the basalt fibre expanded the strength of concrete notwithstanding when unprotected to sulphate attack bit by bit when compared with consistent concrete. The ideal strength of concrete was accomplished with an enlargement of 2 % basalt fibre.

Basalt fibres are inorganic man-made fibres which, in fibre-reinforced plastic composites (FRP), represent a cost-effective alternative to carbon fibres. Within petrochemical thermoplastic matrices, basalt fibres are established in technical applications. The use of biobased polyamides as matrix material is an innovative approach for the production of FRP with a high proportion of renewable raw materials. In addition to material selection, the compound manufacturing process also defines the properties of the FRP. At the Institute of Lightweight Structures, extensive investigations are carried out into material development and optimization of the associated process technology. As a result, basalt fibre-reinforced, biobased polyamides are produced whose mechanical relevant properties are above those of petrochemical based glass fibre-reinforced polyamides.

The Achilles heel of thermoplastic natural fibre composites is their limited durability. The environmental degradation of the mechanical properties of hemp and hemp/basalt hybrid-reinforced high-density polyethylene (HDPE) composites has been investigated with a special focus on the effects of water ageing and accelerated ageing, including hygrothermal and UV radiation. Modification of the matrix was carried out using a maleic anhydride high-density polyethylene copolymer (MAPE) as a compatibilizer. Hybridization of hemp fibres with basalt fibres and the incorporation of MAPE were found to significantly decrease the water uptake (up to 75%) and increase the retention of mechanical properties after accelerated ageing. Secondary crystallization phenomena occurring in the composites, as confirmed by differential scanning calorimetry (DSC) analysis, were able to counteract the severe combined effects of hygrothermal stress and UV radiation, with the exception of hemp-fibre composites where permanent damage to the fibres occurred, with 2% and 20% reduction in tensile strength and modulus, respectively, for a 30 wt % hemp fibre-reinforced HDPE.

The disposal of fibre reinforced composite materials is a problem widely debated in the literature. This work explores the ability to restore the mechanical properties of thermally conditioned basalt fibres through chemical treatments. Inorganic acid (HF) and alkaline (NaOH) treatments proved to be effective in regenerating the mechanical strength of recycled basalt fibres, with up to 94% recovery of the strength on treatment with NaOH. In particular, HF treatment proved to be less effective compared to NaOH, therefore pointing towards a more environmentally sustainable approach considering the disposal issues linked to the use of HF. Moreover, the strength regeneration was found to be dependent on the level of temperature experienced during the thermal treatment process, with decreasing effectiveness as a function of increasing temperature. SEM analysis of the fibres’ lateral surfaces suggests that surface defects removal induced by the etching reaction is the mechanism controlling recovery of fibre mechanical properties. In addition, studies on the fracture toughness of the regenerated single fibres were carried out, using focussed ion beam (FIB) milling technique, to investigate whether any structural change in the bulk fibre occurred after thermal exposure and chemical regeneration. A significant increase in the fracture toughness for the regenerated fibres, in comparison with the as-received and heat-treated basalt ones, was measured.

The study of mechanical properties of fibre reinforced polymeric materials under different environmental conditions is much important. This is because materials with superior ageing resistance can be satisfactorily durable. Moisture effects in fibre reinforced plastic composites have been widely studied. Basalt fibre reinforced unsaturated polyester resin composites were subjected to water immersion tests using both sea and normal water in order to study the effects of water absorption behavior on mechanical properties. Composites specimens containing woven basalt, short basalt, and alkaline and acid treated basalt fibres were prepared. Water absorption tests were conducted by immersing specimens in water at room temperature for different time periods till they reached their saturation state. The tensile, flexural, and impact properties of water immersed specimens were conducted and compared with dry specimens as per the ASTM standard. It is concluded that the water uptake of basalt fibre is considerable loss in the mechanical properties of the composites.

This paper deals with the experiment investigations on the Basalt Fibre Reinforced Polymer composites wrapped concrete specimens for determining the mathematical prediction for retrofitting of concrete specimens. For the past three decades, fibres are being effectively utilized in engineering fields. Some countries do not have specified codes for structural designing of Fibre Reinforced Polymer composites. Especially for this situation, the mathematical predictions were determined by experimentally for Basalt Fibre Reinforced Polymer composites retrofitted concrete. For this experiment, cubes, cylinders and prisms were cast using M30 grade concrete to analyze the characteristic strengths. The tests were carried out with and without Basalt Fibre Reinforced Polymer wrapping and retrofitted after 0%, 30%, 60% and 90% fatigue loaded or preloaded specimens. The retrofitted specimens with Basalt Fibre Reinforced Polymer wrapping, even after 90% fatigue loaded possess higher strength than conventional one. The observed readings were analyzed and mathematical prediction was developed by using readings and graphical representations. From the study, similar results were observed through experiments and mathematical predictions.

Reinforced concrete facades exist since decades exposed to natural weather conditions. Thus nowadays lot of them are damaged by carbonation induced corrosion and therefor require repairing and retrofitting. The aim of this research project is to investigate the possibilities of basalt fibre reinforced concrete as repairing material and also basalt rebars as additional strengthening reinforcement. Investigations with basalt fibre reinforced mortar prisms showed best results in 3 point bending tests, tensile strength and also compressive strength using 0.3 Vol.-% basalt fibres in mixture. The mechanical properties of basalt rebars made of basalt fibre reinforced polymer were tested, showing higher values in tensile strength and Young´s Modulus than comparable steel reinforcement samples. The basalt rebar reinforced concrete samples achieved higher ultimate loads in three-point bending test compared to SRC samples. But after failure in the bonding area no residual load capacity remained. Finally basalt reinforcement bars seems to be well suited for use as retrofitting material for facade elements, but numerous properties have to be examined in further investigations.

Basalt fibre is derived from volcanic rocks and has similar mechanical properties as glass fibre. However, poor fibre-matrix compatibility and processing issues are the main factors that have restricted the mechanical performance of basalt fibre-reinforced thermoplastic composites (BFRTP). In this work, basalt continuous fibre composites with polypropylene (PP) and polycarbonate (PC) matrices were studied. The composites were processed by compression moulding, and a processing study was conducted to achieve good quality composites. For the BF-PC composites, the optimisation of material preparation and processing steps allowed the polymer to impregnate the fibres with minimal fibre movements, hence improving impregnation and mechanical properties. For BF-PP composites, a compatibiliser was required to improve fibre-matrix compatibility. The compatibiliser significantly improved the tensile and impact strength values for short BF-PP composites and continued to increase at 40 wt%. Furthermore, the analytical modelling of the Young’s moduli indicated that the induced fibre orientation during processing for short BF-PP composites and unidirectional (UD) BF-PC composites had better stress transfer than that of UD BF-PP composites.

AbstractPolymers are widely used as replacements for machined metal components in engineering applications. To withstand extreme contact conditions, reinforcing materials are often introduced into polymers to improve their mechanical and wear properties. This paper investigates the applicability of basalt fibres as reinforcing materials to enhance the mechanical and wear properties of polyetheretherketone (PEEK). The weight percentage of short basalt fibres in PEEK composites was 0-10% based on the injection moulding method. The mechanical properties and tribological behaviours of the resulting composites were investigated. The results showed that the composites filled with basalt fibres exhibit significant improvements in strength, anti-indentation creep and hardness. Meanwhile, the friction coefficient and wear rate of the composites decreased obviously due to basalt fibres on the top of the worn surface bearing the dynamic load under sliding. The morphology of the worn surface indicates that fibre pull-out and fibre breakage both contribute to energy dissipation. However, the mechanical properties of the composites did not increase linearly with increasing fibre content because of the decreasing bonding force between the fibres and the matrix. These results are significant for the application of PEEK in engineering.

In the current study the moment - curvature behavior of basalt fibred concrete beams made with basalt fibre reinforced polymer bars and normal beams with steel rebars are evaluated. Basalt fibred reinforced concrete beams of M30 grade were casted with steel and BFRP rebars separately to study the flexural properties of basalt fibre and BFRP bars. From the load –deflection plots, flexural characteristics such as load at first crack, ultimate flexural strength, deflection at the centre and crack width at failure are evaluated. Deflections were measured at the central point and under the load using the deflection meters. The values of moments and curvatures are obtained. Moment curvature relationships are very important to assess out ductility of the structure and the amount of possible redistribution of stresses. The deformations measured are divided by the gauge length (200mm) to obtain the strains at the particular level. From the top and bottom strains, the average curvatures were calculated. From these results, M-Ф diagrams are plotted.

Fibre-reinforced cementitious matrix (FRCM) composites have been effectively used during the last ten years for the strengthening of existing concrete and masonry structures. These composite materials are made of medium- and high-strength fibre meshes embedded in inorganic matrices. Synthetic fibres are the ones that are currently the most used; however, natural fibres, such as basalt fibres, have recently been receiving growing attention. This work presents an extensive experimental study on the mechanical characterisation of a primed basalt fibre bidirectional grid. Fifty monotonic tensile tests on basalt grid strips were performed by varying different parameters, such as the dimension of the specimens, the clamping system, the measurement system and the test rate. Some of the tests were carried out using a video-extensometer to measure each specimen’s strain. The aim of the study was to find the most suitable setup for the tensile characterisation of basalt textiles, in particular, to prevent slippage of the samples at the gripping area and fully exploit the tensile capacity of the grid.

The presented work reveals the strength properties of M70 grade high performance basalt fibre reinforced concrete (BFRCC) containing 0.2%, 0.3% and 0.4% basalt fibre content by volume of concrete. 10% Silica fume is admixed for attaining higher strengths as preferred. Compressive, split-tensile and flexural strengths are evaluated. The BFRCC microstructure is found to be improved due to enrichment of interfacial transition zone with chopped basalt fibres. It was found that different fibre lengths require different dosages to yield maximum effect on the properties of concrete. Stress- strain responses of M70 grade BFRSCC yields improved ultimate strain and strain at peak load indicating its energy dissipation capacity at fracture.

Different compositions of carbon fibre (Cf) - basalt fibre (Bf)/ Epoxy Resin (EP) Composites were fabricated. The mechanical properties were investigated and the microstructure was observed by SEM. The results showed that, the mechanical properties would be improved when suitable content (10-20vol.% of total fibre) of basalt fibre added into carbon fibre/ epoxy composites. It was because that elasticity modulus of basalt fibre was larger than carbon fibre, and for existing of more hydroxyl groups and other active groups, the bonding between basalt fibre and epoxy resin was also better than the bonding between carbon fibre and epoxy resin.

In the present work, assessment of corrosion resistance for M30 grade concrete made with basalt fibres in terms of Resistivity, Potentials and Chloride ion diffusion is made to understand the corrosion resistance studies of concrete specimen made with basalt fibre and BFRP bars. The time of total charge passing till full crack failure for different effective covers considered is more for M30 grade concrete beams made with basalt fibres and BFRP rebars. The time of total charge passing at failure in M30 grade concrete beams made with basalt fibres and BFRP rebars is more because beam specimens did not develop any fissures or micro cracks. Measured electrical resistivity values of M30 grade concrete beams made with basalt fibres have shown high electrical resistance indicating their superior corrosion inhibition ability. M30 grade concrete beams made with basalt fibres and BFRP rebars used for the study exhibited very less probability (less than 5% probability) for corrosion at 28 days.

In this work, an investigation is made to evaluate the flexural toughness of hybrid fibre-reinforced high-performance concrete (HPC) containing different combinations of basalt (B) and polypropylene (P) fibres. The experimental studies consisted of the three-point flexural tests on notched beam specimens. The specimens incorporated basalt/polypropylene (BP) fibres in 11 mixtures with proportions of 0/0, 100/0, 75/25, 50/50, 25/75, and 0/100% by volume at total volume fractions of 1 and 2%. The evaluation of the experimental results was done according to the CECS 13:2009 and PCS (postcrack strength) methods. The results indicate that high-performance concrete containing basalt/polypropylene fibre mixtures of 50/50% and with only polypropylene fibre content of 0/100% can be pronounced as the most appropriate combinations to be used in high-performance concrete for flexural toughness.

The drawbacks are that the concrete has been improved by using hybrid fibre in concrete. By hybridization benefits from two different fibres are utilized in a single concrete mixture. The hybrids fibres studied are basalt-polypropylene fibre, polypropylene-steel fibre, steel-coconut fibre, polypropylene-e-waste fibre, polypropylene-polyvinyl Alcohol and steel-glass- polypropylene fibre. The properties that are improved using hybrid fibres are compressive strength, tensile strength, flexural strength, limited crack propagation, and improved durability of the concrete structure. In maximum cases slump value decrease with an increase in fibre percentage.

Abstract Concrete is a popular building material because of its great compressive strength, durability, and availability of sub-components. The strain at fracture and tensile strength of normal concrete are extremely poor. Simple concrete usually contains multiple micro-cracks and fails due to a lack of tensile strength under continuous loading conditions. Concrete is strengthened with fibres to increase tensile and flexure strength. Fibre-reinforced concrete’s primary function is to monitor cracking and thus provide some post-cracking ductility. The aim is to compare the performance of fibres on the mechanical properties of M30 grade concrete and to find the optimal fibre concentration. Fibres are added by 0.5%, 1%, 1.5% and 2% in concrete. Ternary blended concrete was considered in the study. Cement is partially replaced by GGBS with 30% and Dolomite powder 10% respectively. The study took in to account the replacement to reduce the CO2 emission while also conserving natural resources. Total 8 mixes are prepared with fibre proportions. Different concrete specimens such as cubes, cylinders and beams are prepared with different proportions of fibres. Prepared concrete specimens were tested at 3, 7& 28days. The inclusion of fibres resulted in significant improvements in compression, flexure, and split tensile strength in experimental test results.

— The aim of the present work is to investigate the mechanical properties and water absorption capacity of carbon and basalt fibers mixed with epoxy. At present there is demand for natural friendly products. Basalt reinforced composites developed recently and these mineral amorphous fibres are a valid alternative to carbon fibers for their lower cost and to glass fibres for their strength. The present paper describes briefly on basalt and carbon fibers (unidirectional) which are used as reinforcement material for composites. The matrix epoxy (LY556-HY 951) is taken in to account to access to influence on the evaluated parameters. In order to use reinforced composites for structural applications, it is necessary to perform a mechanical characterization. With this aim experiments like tensile strength, flexural strength, hardness and water absorptions are performed. Later the mechanical properties obtained from experiments are compared with ANSYS software results.

Moisture absorption results in dimensional deformation, mechanical property deterioration and fungi attack in wood composite products, which may be improved by the reinforcement of waterproof material. In this study, we used basalt fibre as a reinforcement material for fir sawdust panels and investigated the influence of basalt fibre content and length on moisture absorption rate and thickness swelling. The reinforced fir sawdust panel groups largely reduced water absorption rate, and the smallest thickness swelling occurred when the content of basalt fibre was 5%. The results also indicated that the basalt fibre content played a more important role than basalt fibre length on the thickness swelling of the reinforced fir sawdust panels.

Full textAbstract:
The results of flexural tests of basalt fibre-reinforced cementitious mortars in terms of flexural strength and the occurrence of the bridging effect are summarised. Mixture proportions and curing conditions were altered for various series. The main parameters concerning mixture proportions were water to cement ratio (w/c), micro-silica and plasticiser addition and fibre dosage (1%, 3% and 6.2% by binder’s mass). Various curing conditions were defined by different temperatures, humidity and time. The influence of the amount of water inside the pores of the hardened cementitious matrix on the flexural strength values, as far as the impact of the alkaline environment on basalt fibres’ performance is concerned, was underlined. The designation of flexural strength and the analysis of post-critical deformations were also performed on the reference series without fibres and with the addition of more common polypropylene fibres. The bridging effect was observed only for the basalt fibre-reinforced mortar specimens with a relatively low amount of cement and high w/c ratio, especially after a short time of hardening. For the lowest value of w/c ratio (equalling 0.5), the bridging effect did not occur, but flexural strength was higher than in the case of non-reinforced specimens. Comparing mortars with the addition of basalt and polypropylene fibres, the former demonstrated higher values of flexural strength (assuming the same percentage dosage by the mass of the binder). Nevertheless, the bridging effect in that case was obtained only for polypropylene fibres.

Fibre-reinforced polymer bars have been widely used for strengthening concrete members due to their high strength, light weight and strong corrosion resistance. A near-surface mounted strengthening system has been adopted to protect the fibre-reinforced polymer bars from external hazards. To make up the lower stiffness and ductility of fibre-reinforced polymer bar compared to steel rebar, this study proposed to use a pre-stressed near-surface mounted steel–basalt-fibre-reinforced polymer composite bar. The steel–basalt-fibre-reinforced polymer composite bar is manufactured through wrapping a steel rod by a basalt-fibre-reinforced polymer cover. A total of nine reinforced concrete beams, including one control or calibration and eight others strengthened by pre-stressed near-surface mounted steel–basalt-fibre-reinforced polymer composite bars, are fabricated and tested. Results show that the proposed steel–basalt-fibre-reinforced polymer composite bar strengthening method can improve both the strength and ductility of the reinforced concrete beams. Pre-stressing of the steel–basalt-fibre-reinforced polymer composite bars further increases substantially the beams’ load-carrying capacity by restraining crack propagation in concrete. Standard-based load analysis correctly predicts the cracking load, however, underestimates the ultimate strength of the beams. Finite element method modelling is conducted to provide a more effective load-carrying capacity prediction and a case study is carried out with regard to the amount of the strengthening steel–basalt-fibre-reinforced polymer composite bars.

Full textAbstract:
The composites based on basalt fibres and poly(lactic acid) (PLA) show promising applications in biomedical and automotive fields, but their mechanical performance is still largely hindered by poor interfacial properties. Zinc oxide nanorods have been successfully used to tune the PLA/basalt fibre interface by growing them on commercially available basalt fabrics. The hierarchical fibres significantly enhanced the mechanical properties of PLA-based composites, especially their flexural strength and stiffness. These values are 26% and 22% higher than those of unmodified basalt/PLA composites, and 24% and 34% higher than those of glass/PLA composites used as a baseline. The increase in tensile and flexural properties hinges on the mechanical interlocking action promoted by ZnO nanorods and on the creation of a compact transcrystallinity structure. A degradation of PLA matrix was detected but it was positively counteracted by the better interfacial stress transfer. This study offers a novel approach for modifying the fibre–matrix interface of biocomposites intended for high-performance applications.

To improve practical application of modern bamboo structures, strengthening the bamboo engineering material is necessary to overcome insufficient stiffness. As an essential step in developing fibre-reinforced polymer–bamboo engineering material composite structures aimed at increasing the structural stiffness, the bonding behaviour at the interface of the fibre-reinforced polymer and bamboo engineering materials should be investigated in detail because currently there is a lack of research. In this article, bonding behaviour is studied between basalt fibre-reinforced polymer bar and bamboo engineering material including laminated and reconstituted bamboo and between basalt fibre-reinforced polymer sheets and laminated bamboo. Failure patterns are categorized, and the load–slip curves are discussed. Based on the failure pattern and strain variation, recommended bond lengths were proposed for the basalt fibre-reinforced polymer bar–bamboo engineering material and basalt fibre-reinforced polymer sheet–laminated bamboo composite specimens, respectively. In addition, a simplified three-phase bond–slip model was proposed for the basalt fibre-reinforced polymer bar–bamboo engineering material composite specimen.

In general, 20–25% of the original fibre weight is considered waste in the production of high-quality textiles for the construction sector. A market analysis has shown that in the Republic of Croatia alone, up to 327 tonnes of this waste is produced annually, which is enough to reinforce 50 to 150 thousand m3 of cementitious composites. This preliminary study aims to evaluate the contribution of glass, basalt and carbon fibres generated as waste in the local production of high-performance technical textiles, to the fresh and hardened properties of fibre reinforced mortars. In order to investigate the influence of fibres, three types of fibres in two different lengths (5 and 10 mm) were used, while the amount of fibres was constant. The obtained results show that due to the fibre presence, workability is reduced regardless of the type and length of the fibre. The tested fibres have a negligible effect on compressive strength, but the use of basalt and carbon fibres increases the tensile strength. Furthermore, all three types have positive influence on the toughness and volumetric deformations, although to a greater extent in the use of 10 mm long fibres and carbon fibres.

Abstract. West Java there is a lot of wealth of mining materials as a result of volcanic activities including andesite and basalt. Mining materials are generally conventionally used only for building materials (construction) in the field of Civil Engineering which is still in the form of 'raw materials' or 'semi-finished'. The management of this mining material is carried out with simple and the selling value is low.In the century of advanced technology today began to be widely used construction materials in the form of composites with fiber reinforcement (Fibre Reinforced Composite), including composites with the strengthening of basalt fibers (Fibre Basalt Reinforced Composite). Basalt fibers have attracted a lot of attention in the composite industry because they are chemically stable and have excellent mechanical and thermal properties. Due to its high commercial value, basalt fiber has many applications in the polymer and construction industries.In this case, the question is whether there isa great potential,is it possible that basalt around Bandung Raya can be used as basalt fiber so that it can provide added value? Whether the quality (chemical/mineral arrangement) and characteristics are in accordance with the physical and mechanical properties required to be used as basalt fibers.In the research will be determined characteristics, quality (chemical / mineral arrangement) in several research locations that have the potential of basalt rock deposits, namely around Bandung and Cimahi, Cianjur, Cikarang and Serang. In testing the physical-mechanical properties of the three regional representatives from the three research areas included in the test parameters, namely samples BT 01 and GB 02.

Bahan tambang itu pada umumnya secara konvensional digunakan hanya untuk bahan bangunan (konstruksi) di bidang teknik sipil yang masih dalam bentuk „bahan mentah‟ atau „setengah jadi‟. Pengelolaan bahan tambang ini dilakukan dengan relatif sederhana dan nilai jualnya yang relatif rendah.Pada abad teknologi maju sekarang ini mulai banyak digunakan bahan konstruksi yang berbentuk komposit dengan penguatan serat (fibre reinforced composite), diantaranya adalah komposit dengan penguatan serat basalt (fibre basalt reinforced composite). Serat basalt telah menarik banyak perhatian dalam industri komposit karena secara kimiawi stabil dan memiliki sifat mekanik dan termal yang sangat baik. Karena nilai komersialnya yang tinggi, serat basalt memiliki banyak aplikasi dalam industri polimer dan konstruksi. Dalam hal ini yang menjadi pertanyaan apakah dengan potensi yang besar, mungkinkah basalt di sekitar Wilayah Bandung Raya ini bisa dijadikan serat basalt sehingga dapat memberikan nilai tambah? Apakah kualitas (susunan kimia/mineral) dan karakteristik sesuai dengan sifat-sifat fisik dan mekanik yang dipersyaratkan untuk dijadikan serat basalt.Dalam penelitian akan ditentukan karakteristik, kualitas (susunan kimia/mineral) di beberapa lokasi penelitian yang mempunyai potensi endapan batuan basalt yaitu di sekitar Bandung dan Cimahi, Cianjur, Cikarang dan Serang.

This study investigates the fracture properties of high performance cementitious composites (HPCC) with four different types of fibres and with volume fraction content 3%. The four fibres are steel hooked end (S), polypropylene crimped (PP), basalt chopped (B), and glass (G) fibres. The tests were carried out in accordance with the RILEM recommendations. In order to examine the fresh properties of HPCC the slump flow tests were performed. Twelve fibre reinforced HPCC beam specimens with notch were cast and tested using central point loading experiments. In addition, experimental tests of the compressive strength and splitting tensile strength were carried out. The test results made it possible to obtain representative fracture parameters, such as the equivalent strengths, residual strengths, and fracture energy of fibre reinforced HPCC. The S fibre specimens showed the best performance in terms of workability, compressive strength, tensile splitting strength, and fracture energy at large deflection. On the other hand, G fibre specimens exhibited the best performance in terms of flexural strength, equivalent flexural strength at higher deflection, and residual flexural strength at lower deflection. In terms of equivalent flexural strength at lower deflection and residual flexural strength at higher deflection, basalt fibre specimens performed the best. On the contrary, polypropylene fibre reinforced beam specimens revealed the highest deflection capacity.

AbstractIn this work, geopolymer foam composites containing waste basalt fibre (10, 30, and 50%wt) were exposed to elevated temperatures of 200, 400, 600, 800 and 1000∘C. With an increase in high temperature, the geopolymer foams material exhibits a decrease in compressive strength and bending strength. When heated above 600∘C, geopolymer foams materials exhibit a significant reduction in mechanical properties. It shows clearly with the naked eye that surface cracks in case of samples containing 10% of basalt filler. However, when increasing fillers with basalt fibres up to 30% and 50%, the cracking of the sample surface is no longer visible to the naked eye. Especially when the temperature increases, the mechanical properties also increase without decreasing in the sample of 50% by weighing to the binder. The results show that reinforcing the geopolymer foams with basalt ground fibre improves the mechanical properties at high temperatures.

Results showed that when the thickness of the graphene coating was 2.0 mm, the polarising ability, loss ability and attenuating ability of the fabric with respect to electromagnetic waves were all the largest. Along with the increasing thicknesses of the graphene coating, the electromagnetic shielding effectiveness of the double-layer coated basalt fibre fabric also increased, then the shielding ability against electromagnetic waves became stronger.

Recently, short basalt fibres (BFs) have been gaining considerable attention in the building materials industry because of their excellent mechanical properties and lower production cost than their counterparts. Reinforcing geopolymer composites with small volumes of fibres has been proven an efficient technique to enhance concrete's mechanical properties and durability. However, to date, no study has investigated the effect of basalt fibers’ various lengths and volume content on self-compacted geopolymer concrete's fresh and mechanical properties (SCGC). SCGC is prepared by mixing fly ash, slag, and micro fly ash as the binder with a solid alkali-activator compound named anhydrous sodium metasilicate (Na₂SiO₃). In the present study, a hybrid length of long and short basalt fibres with different weight contents were investigated to reap the benefits of multi-scale characteristics of a single fibre type. A total of 10 mixtures were developed incorporating a single length and a hybrid mix of long (30) mm and short (12) mm basalt fibres, with a weight of 1%, 1.5% and 2% of the total binder content, respectively. The fresh and mechanical properties of SCGC incorporating a hybrid mix of long and short basalt fibres were compared to plain SCGC and SCGC containing a single fibres length. The results indicate that the hybridization of long and short fibres in SCGC mixture yields better mechanical properties than single-length BF-reinforced SCGC. A hybrid fibre coefficient equation will be validated against the mechanical properties results obtained from the current experimental investigation on SCGC to assess its applicability for different concrete mixes.

Basalt reinforced composites are quite recently (during last 20 years) developed materials having low density, high specific strength, good frictional, heat and chemical resistance. Natural mineral based fibres are potential alternatives to glass fibres for their strength and to carbon fibres for their lower cost. In order to use basalt reinforced composites for lightweight applications, it is necessary to perform wear characterisation. Basalt fibre, powder and scales reinforced, unsaturated polyester and epoxy resin composites were fabricated with various ratios of basalt and polymeric matrixes. The tribological behaviour of basalt reinforced composites was determined according to the ASTM G132 standard test method for pin abrasion testing. Results showed that type and content of reinforcement have a significant influence on the mechanical and tribological properties of the composites. Scanning electron microscope images are given to illustrate the wear mechanism of composites.

The purpose of this paper is to demonstrate the properties of glued laminated beams made in diverse configurations of timber quality classes, reinforced using a new technique that is cheaper and easy to apply. The aim of the experimental investigations was to enhance reinforcement effectiveness and rigidity of glued laminated beams. The tests consisted of four-point bending of large-scale specimens reinforced with basalt fibres (BFRP). The tests were meant to obtain images of failure, the load–displacement relation and load carrying capacity of basalt fibres depending on the reinforcement ratio. The tests, which concerned low and average quality timber beams, were conducted in a few stages. The aim of the study was to popularize and increase the use of low-quality timber harvested from reafforested areas for structural applications. In the study, theoretical and numerical analysis was carried out for reinforced and unreinforced elements in various configurations of wood quality classes. The aim was to compare the results with the findings of experimental tests. Based on the tests, it was found that the load carrying capacity of beams reinforced with basalt fibre was higher by, respectively, 13% and 20% than that of reference beams, while their rigidity improved by, respectively, 9.99% and 17.13%. The experimental tests confirmed that basalt fibres are an effective structural reinforcement of structural timber with reduced mechanical properties.

To boost the output parameters, the process parameters have to be optimized; which is the aim of this project. Centered within various layers of Jute / Basalt and material orientation, the orthogonal series of various experiments are performed using the relevant Taguchi technique. The aim of these experiments is to provide a relationship between process and performance parameters to enhance the overall performance of the substance under various conditions. The effect of Basalt fibre and Jute fibre orientation during Tension and Hardness is studied in the present work. The tests are arranged according to the orthogonal array of Taguchi L9. Using ANOVA (Analysis of Variance), the experimental results are statistically analyzed to correlate the parameters and answers. It was observed from the experimental findings that orientation was perceived to be the most important element affecting the intensity of the substance proposed. By considering the optimum composition through analysis, water absorption test is performed with respect to number of days with Basalt and Jute as outer layers to study and compare the water absorption percentage of both the fibers. SEM analysis is performed to study the fiber intactness and surface morphology of the optimum sample, after every experimentation. Experimental studies have shown that hybridization of Basalt fibre jute epoxy shows greater tolerance to strength.

Sixteen mixtures consisting of PP and BF, both at volume content of 0.0, 0.1, 0.2 and 0.3%, were fabricated, and the slump, compressive, splitting tensile, flexural and charge passed were tested. The results show the hybridization of the PP and BF can improve three types of strength of concrete in comparison to their single fibre. Nevertheless, the hybridization is not always conducive, and the synergy of fibres is proposed and divided into positive and negative effects. The combination of the PP and BF both at content of 0.1% achieves the best mechanical performance, and is recommended for practical usage. Incorporating fibres reduces the chloride resistance of concrete, and the hybridization is helpless to this phenomenon; even the reduction is intensified at a highly hybrid fibre volume. However, increasing the curing age can mitigate this adverse effect caused by fibres. Furthermore, the microstructures were explored to elucidate the macro-properties of concrete in terms of interface and pore structure.
