Abstract:

Textile-reinforced concrete (TRC) is a reinforced concrete, where steel reinforcement is replaced with textiles or fibers. Textile reinforcement is a material consisting of natural or synthetic singular technical fibres processed into yarns or rovings which are woven into multi-axial textile fabrics having an open mesh or grid structure. In the paper an overview of tests results related to mechanical properties, deformation properties and durability characteristics of textile meshs are presented. Applications of different textiles as reinforcement in TRC is analyzed through some realized projects. TRC has been successfully employed for strengthening or repair of damaged structural elements and lightweight, thin structural elements (precast thin-walled elements, shells, tanks, pipes, pedestrian bridge, waterproofing structure, integrated cladding systems, external insulation system).

Abstract:

This paper presents an experimental program of initial testing of reinforced concrete beams using bars and textiles carried out with an aim of comparative analysis of the behaviour of reinforced concrete beams using textiles in relation to conventional reinforced beams. Alkalineresistant glass fibre textile meshes were used for the purposes of the experiment. An experiment setting is described and obtained test results are presented in this paper. An analysis of the obtained results is presented at the end of the paper. The experimental program demonstrated that adding textile mesh, besides improvement of the durability of the protective layer of concrete, can improve the load-bearing capacity and ductility of reinforced concrete beams. There is still an issue related to workability of concrete in textile reinforced beams and achievement of full adhesion between textile mesh and concrete. At the end of the paper, a suggestion was given about semi-prefabricated reinforced concrete beams using reinforced bars and textiles.

Abstract:

In this study, nine specimens were experimentally tested to analyze the strengthening efficiency of textile-reinforced mortar (TRM) and the difference in flexural behavior between prestressed and non-prestressed TRM-strengthened reinforced concrete beam. The test results show that TRM strengthening improves the flexural strength of TRM-strengthened reinforced concrete beams with alkali-resistant-(AR-) glass textile as well as that with carbon textile. However, in the case of textile prestressing, the strengthening efficiency for flexural strength of the AR-glass textile was higher than that of the carbon textile. The flexural stiffness of AR-glass textiles increased when prestressing was introduced and the use of carbon textiles can be advantageous to reduce the decreasing ratio of flexural stiffness as the load increased. In the failure mode, textile prestressing prevents the damage of textiles effectively owing to the crack and induces the debonding of the TRM.

Abstract:

This paper discusses the state of the art in research on the use of textile-reinforced concretes in structural maintenance. Textile-reinforced concretes can be used in structural maintenance for various purposes, including the sealing and protection of the existing building structures, as well as for the strengthening of structures. The first-mentioned aspects are explained in this paper on the basis of example applications. A special focus is placed on the maintenance of heritage-protected structures. The development, characterization, and testing of a textile-reinforced concrete system for a heritage-protected structure are presented. Examples of the application of textile-reinforced concrete for strengthening highway pavements and masonry are also given.

Abstract:

A series of flexural tests were performed in order to investigate the effect of steel fiber reinforcement (SFR) in textile-reinforced concrete (TRC) plates. Some of the specimens were reinforced only with textile, some of them only with fibers, and some of them were provided with both textile and fiber reinforcement. The concrete matrix was a self-developed ultrahigh performance concrete (UHPC) mixture with a compression strength over 160 MPa. The tensile strength of the used textiles was around 1500 MPa for glass fiber textile and over 3000 MPa for carbon fiber textile. In case of fiber reinforcement, the concrete was reinforced with 2 vol% of 15 mm long and 0.2 mm diameter plain high strength steel fibers. The dimensions of the rectangular plate test specimens were 700 × 150 × 30 mm. The plate specimens were tested in a symmetric four-point bending setup with a universal testing machine. The tests were monitored using a photogrammetric measurement system with digital image correlation (DIC). The paper presents and evaluates the test results, analyses the crack patterns and crack development, and compares the failure modes. The results showed a general advantageous mechanical behavior of specimens reinforced with the combination of fibers and textiles in comparison to the specimens reinforced with only fiber or textile reinforcement.

Abstract:

The effectiveness of textile-reinforced concrete (TRC) and steel-reinforced concrete (SRC) in the flexural performance of rectangular concrete beams was investigated in this study. To better understand TRC behaviour, large-scale concrete beams of 120 × 200 × 2600 mm were tested and analysed in this work. Cover thickness, anchoring, and various layouts were all taken into consideration to assess the performance of beams. In addition, bi-axial and uni-axial TRC beams and SRC beams were classified according to the sort and arrangement of reinforcements. The findings showed that anchoring the textiles at both ends enhanced load resistance and prevented sliding. The ultimate load of the tow type of textile reinforcement was higher, attributed to the increased bond. Variations in cover thickness also change the ultimate load and deflection, according to the findings. Consequently, in this investigation, the ideal cover thickness was determined to be 30 mm. Furthermore, for the similar area of reinforcements, the ultimate load of TRC beams was noted up to 56% higher than that of the SRC control beam, while the deflection was roughly 37% lower.

Abstract:

Textile-reinforced concrete (TRC) is a form of reinforced concrete, where conventional reinforcement is replaced with textiles or fibers. The high tenacity of the textile fibers results in flexible and durable concrete structures. The literature has been limited to TRC applications in retrofitting and nonstructural applications. Therefore, this article attempts to detangle the progressive research direction on the usage of TRC as a structural member. For this, (i) a bibliometric study using scientometrics analysis to visualize the keyword network, and (ii) qualitative discussions on identified research areas were performed. The literature was categorized into four main research areas, namely material properties of TRC, composite behavior of TRC, bond-slip relations, and TRC applications as structural elements. In addition, the advantages and disadvantages in the usage of TRC as a structural member are discussed in association with the identified research areas. Furthermore, the article proposes future directions to reinforce the research on the usage of TRC as a structural element.

Abstract:

Textile-reinforced mortar (TRM) is used to strengthen reinforced concrete (RC) structures using a textile and inorganic matrix. TRM is a part of textile-based composites; the basic structural behaviors, application methods, and methodologies for the extension of actual structures in TRM were studied. However, structural behavior and performance verification which depict the long-term service situation and fatigue is limited. Therefore, this study, verified the flexural behavior of TRM-strengthened beams and their fatigue performances using carbon- and alkali-resistant (AR) glass textiles through 200,000 load cycles. TRM-strengthened beams were applied to an optimization strengthening method which consisted of whether the textile was straightened. According to the test results, the strengthening efficiency of TRM-strengthened beams when subjected to cyclic loading was lower than that of the monotonic loading, except for the straightened carbon textile specimen. The average efficiency of the AR-glass textile (straightened and non-straightened) and carbon (non-straightened) was 0.86 compared to the TRM-strengthened beam subjected to monotonic loading in terms of flexural strength. In the case of deflection, the average efficiency of the AR-glass textile type was similar to the monotonic loading test results, while that of the non-straightened carbon textile was improved. The Ca-S specimen that was used to straighten the carbon textile showed a reliable structural performance with a strength efficiency of 0.99 and a deflection efficiency of 0.97 compared to the monotonic load test. Therefore, TRM strengthening using a straightened carbon textile is expected to be sufficient for the fatigue design of TRM-strengthened beams.

Abstract:

In this study, one reinforced concrete specimen and six textile reinforced concrete (TRC) specimens were produced to analyze the flexural behavior of steel-textile-reinforced concrete. The TRC specimen was manufactured using a total of four variables: textile reinforcement amount, textile reinforcement hook, textile mesh type, textile lay out form. Flexural performance increases with textile reinforcement amount, textile reinforcement hook type and textile reinforcement mesh type. The flexural performance was improved when physical hooks were used. Furthermore, textile reinforcement was verified as being effective at controlling the deflection.

Abstract:

Abstract Numerous problems that can occur during regular building use may necessitate the need for reinforced concrete RC members to be strengthened. An increase in live loads or structural damage is two examples. Various techniques can be used to increase load-carrying capability. Concrete reinforcement with textile-carbon fiber (TCF) is a more recent option. For almost all active forces, this strengthening procedure is appropriate. For bending, shear, torsion, or axial forces, strengthening is an option. The experimental work for this study examined the impact of textile carbon mesh in reinforced concrete with various numbers of layers and sikadure-330 as the bonding material with different damage ratio (0%, 45%, 55% and 70%). As well as the flexural behavior of reinforced concrete beams strengthened with TCF, by casting and testing 13 beams under the monotonic load, one of them represented the control beam, they designed according to ACI 318-14 to ensure flexural failure. From the results obtained in this study it was shown that the flexural capacity of all strengthened beams increased as a consequence of TCF strengthening. Therefore, TCF jacketing is a very promising technique for increasing reinforced concrete flexural capability, which is necessary for retrofitting and strengthening.

Abstract:

Demand for very thin concrete elements, which can’t be reinforced with usually used steel reinforcement, gave rise to a new type of non-traditional reinforcement with technical textiles in matrix of epoxy resin. This type of reinforcement together with concrete is called textile reinforced concrete (TRC). Composite reinforcement is very chemically resistant, so the concrete cover is proposed to regard the durability. It allows a significant saving of concrete and design of thinner elements. For TRC structures is used high performance concrete (HPC) with its fine grained structure and high compressive strength. Textile reinforcement and TRC in general are developed at the Faculty of Civil Engineering and the Klokner Institute, CTU in Prague.

Abstract:

To study the reinforcement effect of textile-reinforced concrete (TRC) on concrete structures in a marine environment, a four-point bending loading method was used for graded loading to analyze the influence of the dry–wet cycle number, the reinforcement method, and chopped fiber addition on the flexural properties of load-holding reinforced concrete beams reinforced with textile-reinforced concrete. The results show that with the increase of dry–wet cycle numbers, the crack width and deflection of beams develop faster and the bearing capacity decreases. The performance of the prefabricated textile-reinforced concrete plate is close to that of a cast-in-place textile-reinforced concrete in limiting crack, bearing capacity, and deflection deformation. The addition of chopped fibers in fine-grained concrete can improve the reinforcement effect of textile-reinforced concrete. Based on the experimental results and referring to the relevant design codes and literature, the calculation formula of the bearing capacity of TRC-strengthened beam with a secondary load is established, and the calculated values are in good agreement with the actual values.

Full text

Abstract:

AbstractThe use of textile reinforced concrete (TRC) is particularly suitable for producing sustainable, material‐minimised components, as it allows for a significant reduction in the amount of concrete cover required compared to steel reinforced concrete (SRC). Instead of steel, fibres made of glass, aramid or carbon are used as reinforcement, which are processed from rovings into textiles with a polymer or mineral impregnation. Among these, carbon reinforcements have the highest tensile strength and alkali resistance, making them the most durable in concrete and requiring less maintenance over time. An innovative approach is the production of TRC structures by means of extrusion, in which the stiff, fresh concrete is continuously pressed through a shaping mouthpiece, giving the product its final shape. Within the scope of the CRC/Transregio 280, a new mouthpiece was developed that enables the horizontal introduction of stiff, impregnated textiles. The carbon TRC produced in this process showed a textile stress of up to 4,000 MPa. Additionally, solutions are presented that allow the characterization of stiff, fresh concrete and technical limits for shaping fresh, extruded TRC elements. The potential of this new production method is illustrated through the example of a compound component made of extruded TRC elements.

Abstract:

Development of extremely thin concrete structures and demand for extremely thin elements are the reason of using composite non-traditional materials as reinforcement. Steel reinforcement is not very chemically resistant and it limits the thickness because of the required concrete cover as protection. This is the reason why textile reinforced concrete (TRC) going to be very famous and modern material. TRC in combination with fine grain high performance concrete (HPC) allows a significant saving of concrete. Due to its non-corrosive properties of composite technical textiles it is possible to design very subtle structures and elements. TRC and HPC in general are developed at the Faculty of Civil Engineering and the Klokner Institute, CTU in Prague. This present paper investigates the cohesion influence of textile reinforcement on four point bending test. All small experimental panels were reinforced with the same 3D technical textile from AR-glass roving with different type of cover layer. Different conditions of interaction between technical textiles and HPC were ensured by modified surface using silica sand and silica flour.

Abstract:

Textile-reinforced concrete is becoming more and more popular. The material enables the realization of very thin structures and shells, often with organic shapes. However, a problem with this reinforcement occurs when the structure is bent (contains a corner), and the flexural stiffness around this bent area is required. This article presents the design, solution, and load-bearing capacity of an L-shaped rigid frame made of textile-reinforced concrete. Basic material parameters of concrete matrix and carbon textile reinforcement were supplemented by a four-point bending test to calibrate fracture energy Gf, critical compressive displacement Wd, solver type, and other parameters of a numerical model created by Atena Engineering in specialized non-linear structural analysis software for reinforced concrete structures. The calibrated numerical model was used to evaluate different variants of carbon textile reinforcement of the L-shaped frame. The carbon textile reinforcement was homogenized using epoxy resin to ensure the interaction of all fibers, and its surface was modified with fine-grained silica sand to increase the cohesion with the concrete matrix. Specimens were produced based on the most effective variant of the L-shaped frame reinforcement to be experimentally tested. Thanks to the original shaping and anchoring of the reinforcement in the corner area, the frame with composite textile reinforcement is rigid and can transmit the bending stresses in both positive and negative directions. The results of the mechanical loading test on small experimental specimens correspond well to the results of numerical modeling using Atena Engineering software.

Abstract:

In the last decades, modern technological and research developments of textile-reinforced concrete have led to extensive applications in building and civil engineering structures all over the world. Examples of textile-reinforced concrete can be found in retrofitting of existing buildings, facade slabs or bridges. Despite its potential, the widespread use of textile-reinforced concrete remains still limited. This is partly explained by the lack of a consistent design framework since conventional design methods used for other materials (e.g., steel reinforced concrete) cannot be directly applicable to textile-reinforced concrete. Thus, procedures to derive partial safety factors for textile-reinforced concrete would be a major step forward towards a regular procedure for the design of structural members made of this material.This paper offers a general procedure to determine safety factors. The approach is illustrated with a bending design example of a textile-reinforced concrete facade slab. The example is calculated in a recently developed software package for structural reliability analysis built in the statistical programming language R. For the derivation of safety factors, initial data is required, which can be obtained from experimental or numerical tests or from literature. The paper includes the basics of data evaluation as well as the statistical characterisation of data extracted from literature.

Abstract:

The influences of the mesh sizes, the surface treatment and cover thickness of the textile on anti-crack and bearing capacity of the competent were investigated. Additionally, to prevent the splitting of the concrete, hanging U-shaped hook upon textiles was also experimentally studied. The experiment results indicate that sticking sand on epoxy resin-impregnated textile and reduced cover thickness are helpful to improve the mechanical performance of the component; the textile with 10mm×10mm mesh size is superior than that with 20mm×20mm mesh size regardless of in the respect of enhancing the bearing capacity of the TRC or in the respect of controlling matrix cracking; the novel method of adding U-shape iron hook not only can improve the bonding performance between the textile and the concrete, but also can enhance the shearing capacity of the concrete.

Abstract:

There has been a rising interest in utilising textile reinforcement such as carbon tows in constructing concrete components to enhance the performance of conventional reinforced concrete. Textile-reinforced concrete (TRC) has been used as a construction material mostly as primary reinforcement. However, the structural performance of TRC members has not been investigated in depth. Therefore, to better understand TRC beams’ behaviour under bending load, a widespread experimental investigation was conducted. The results of tensile stress-strain, load-deflection, moment-curvature, and tension stiffening behaviours of TRC beams were associated with conventional steel-reinforced concrete (SRC) beams. In this study, the four-point bending and tensile strength tests were performed. The results revealed that, unlike the stress-strain behaviour observed in steel, textile reinforcement does not exhibit yielding strain. The flexural behaviour of TRC beams shows no similarity to that of SRC beams at postcracking formation. Besides, the moment capacity and tension stiffening of TRC beams were found 56% and 7 times higher than those of SRC beams, respectively. Therefore, in light of these results, it can be said that TRC beams behaviour differs from that of SRC beams.

Abstract:

In the last 30 years, façade-panels made of steel-reinforced concrete have become less attractive for architects and clients. Due to the metallic reinforcement, the insufficient concrete covers of former design code generations and hence the material-dependent corrosion, many cases of damage occurred. Using technical textiles for a new composite material, Textile Reinforced Concrete (TRC), it is possible to produce concrete structures which are not vulnerable to corrosion. The presented ventilated large-sized façade elements and self-supporting sandwich panels exemplify the capability of TRC. In the paper, applied materials are characterized and the production process of tailor-made textile reinforcements as well as the load-bearing behavior of the members is described.

Textile reinforced concrete (TRC) allows the light weight structures and offers a high effectiveness of the reinforcement by using continuous yarns. The study on the bond behavior between textile and concrete matrix is significant for the development of computational methods that analyze the textile reinforced concrete. The paper analyzes the bonding constitutive model of TRC and the bonding mechanism that the stress is transferred from fine concrete to textile, pointing out quadruple linear model can accurately reflect the bond behavior between fiber and concrete, illustrates the main influences on bond between the fine grained matrix and fabrics based on the pull-out test, the result reveals that with initial bond length increasing, the maximum pull force increases, and increasing concrete strength and improving workability of concrete matrix, epoxy resin impregnating and sand covering of textile as well as prestressing textile can increase the bond strength between textile and concrete. Finally the paper proposes that epoxy resin impregnating and 0.15 ~ 0.30mm sand covering of textile can be used as a practical method of improving bond properties in the engineering.

In civil engineering, steel reinforced concrete is currently still the most widely used composite material. For broad spectrum of utilization is the most important combination of a high compressive and tensile strength [1]. The increasing demand for subtle concrete elements gave impetus to the development of the new materials for the reinforcement of concrete which are non-corrodible and thus do not need such a thick coating layer-technical textiles. These composite materials are known under the title Textile Reinforced Concrete – TRC.

Concrete reinforcement with textile-reinforced materials (TRC) is a more recent option. For almost all active forces, this strengthening procedure is appropriate.

Due to their many appealing qualities, characteristics as their high specific strength (i.e., strength to weight ratio), resistance to corrosion, the convenience of use, speedy installation, and little variation in cross-section, (TRC) have become more and more popular among structural engineers for strengthening and retrofitting projects The conclusions made from the experimental results of members made of reinforced concrete strengthened in shear suggest that textile-mortar composites greatly increase shear resistance, with the gain increasing with the number of layers. This review focuses on strengthening RC beams in flexure by textile-reinforced concrete. According to the authors, TRC jacketing is a very promising technique for increasing reinforced concrete components’ confinement, in addition to their shear and bending capability, which is necessary for seismic retrofitting and strengthening.

Abstract:

This paper presents an experimental study to strengthen flexure-deficient reinforced concrete beams using textile-reinforced mortars (TRMs). A set of seven reinforced concrete beams were strengthened using basalt and carbon TRMs. The current study utilised textiles with almost similar physical properties to strengthen reinforced concrete (RC) beams. All the studied beams were strengthened at their soffit to evaluate the effectiveness of textile fibres, the number of layers and the strengthening configuration. The experimental results showed that beams strengthened using carbon and basalt textile-reinforced mortar performed equally better in terms of overall performance with inherent textile slippage after the peak load. The flexural load capacities of the beams were strengthened with one layer, and three layers were higher when compared to the control beam. For the basalt TRM one, three and five layers registered an increment of 8.3%, 20.7% and 30.3% of ultimate strengths over the unstrengthened specimen. Similarly, for the carbon TRM one, three and five layers recorded an increment of 14.2%, 15.3% and 32.3% of ultimate strengths over the control specimen. Five-layered specimens with end U-wraps successfully mitigated premature debonding, along with registering maximum load capacity, and digital image correlation (DIC) was performed to monitor real-time crack width, crack patterns and spacing and to compare the load and displacement responses from all the tested specimens.

Abstract:

Textile-reinforced concrete (TRC), as a kind of high-crack-resistance and high-corrosion-resistance material, has been widely studied. The current research has begun the exploration of the change of textile form, such as 3D-textile-reinforced concrete (3D TRC), and its superior bending performance has been verified. In order to pursue better mechanical properties, combined with the characteristics of self-stressing concrete and 3D textiles, three-dimensional-textile-reinforced self-stressing concrete (3D-TRSSC) specimens were designed in this research. The expansive and compressive properties of specimens with two types of textiles were tested by self-stress and compressibility tests, and the results showed the compressive property and failure mode of 3D-TRSSC were improved compared with 2D-TRSSC and SSC: the increase in compressive strength was 16.3% and 35.1%, respectively. In order to explain the improvement of the compressive strength of the 3D-TRSSC specimens, the triaxial self-stress state analysis of the compressive specimen was carried out, and then a set of calculation methods based on deformation analysis was designed to explain the upward displacement of the necking position of the TRSSC compressive specimen. The theoretical results and experimental data were 27.2 mm and 28–30 mm, respectively. In addition, the improvement of the compressive strength of the 3D-TRSSC specimens relative to that of the 2D-TRSSC specimen was predicted. The calculation results were highly consistent with the predicted values.

Abstract:

Textile reinforced concrete (TRC) is a sustainable composite material consisting of a cementitious based matrix in combination with an open meshed technical textile reinforcement made of carbon or glass fibres. In the future, TRC could be increasingly used in the form of double-curved concrete elements with the aim of producing filigree yet load-bearing concrete shell structures. To assess whether a textile is suitable as a reinforcement structure in double-curved textile concrete elements, numerous properties need to be investigated and evaluated. The most important of these include good handling properties, bending stiffness tailored to the application, sufficiently pronounced mesh openings, and defect-free drapability. In the course of this work, biaxially reinforced knitted fabrics with five different stitch types (pillar open, pillar closed, tricot counterlaid, tricot closed and plain) were investigated to evaluate the above properties. The draping tests were conducted on a robot-controlled draping test apparatus and evaluated with the aid of an optical measuring system. In addition, the geometric relationship between surface curvature of the double curved elements and the shear angle of different textiles was used to classify the influence of the stitch type on the drapability. Finally, for a given double curved geometry, based on the results the selection of an appropriate textile reinforcement which fulfil the component requirements is carried out and a double curved TRC demonstrator element is prefabricated.

Abstract:

The textile-reinforced concrete composite material (TRC) consists of a mortar/concrete matrix and reinforced by multi-axial textiles (carbon fiber, glass fiber, basalt fiber, etc.). This material has been used widely and increasingly to reinforce and/or strengthen the structural elements of old civil engineering structures thanks to its advantages. This paper presents a numerical approach at the mesoscale for the mechanical behavior of TRC composite under tensile loading. A 2-D finite element model was constructed in ANSYS MECHANICAL software by using the codes. The experimental results on basalt TRC composite from the literature were used as input data in the numerical model. As numerical results, the basalt TRC provides a strain-hardening behavior with three phases, depending on the number of basalt textile layers. In comparison with the experimental results, it could be found an interesting agreement between both results. A parametric study shows the significant influence of the reinforcement ratio on the ultimate strength of the TRC composite. The successful finite element modeling of TRC specimens provides an economical and alternative solution to expensive experimental investigations.

Abstract:

In order to study the influences of the contents of short fiber on the mechanical properties of concrete matrix, the properties of compressive, flexure and splitting of concrete matrix reinforced by alkali resistant glass fiber and calcium carbonate whisker were tested. To study the reinforced effect of different scale fibers on the flexure behavior of fine concrete sheets, the flexural tests of concrete sheet of fine concrete reinforced with basalt fiber mesh and short fiber composites were carried out. The results show that the properties of the compressive, flexure and splitting of fine concrete reinforced with appropriate amount of alkali resistant glass fiber and carbonate whisker are improved compared with that of concrete reinforced by one type of fiber. The flexure properties of the concrete sheets are improved obviously when continuous fiber textile and short fiber composite are adopted to reinforce.

Abstract:

Recently, innovations in textile-reinforced concrete (TRC), such as the use of basalt textile fabrics, the use of high-performance concrete (HPC) matrices, and the admixture of short fibers in a cementitious matrix, have led to a new material called fiber/textile-reinforced concrete (F/TRC), which represents a promising solution for TRC. Although these materials are used in retrofit applications, experimental investigations about the performance of basalt and carbon TRC and F/TRC with HPC matrices number, to the best of the authors’ knowledge, only a few. Therefore, an experimental investigation was conducted on 24 specimens tested under the uniaxial tensile, in which the main variables studied were the use of HPC matrices, different materials of textile fabric (basalt and carbon), the presence or absence of short steel fibers, and the overlap length of the textile fabric. From the test results, it can be seen that the mode of failure of the specimens is mainly governed by the type of textile fabric. Carbon-retrofitted specimens showed higher post-elastic displacement compared with those retrofitted with basalt textile fabrics. Short steel fibers mainly affected the load level of first cracking and ultimate tensile strength.

Abstract:

This article deals with experimental testing of the textile reinforced concrete samples. The main topic of this article is determination ultimate tensile strength of the textile reinforced concrete. The testing samples were in form “dogbone” for good fixing in testing machine. There are 12 samples totally in experimental program. One type cement matrix and three types (difference in their weight 125 g/m2, 275 g/m2 and 500 g/m2) glass textile reinforcement were used for the production of samples. The textile reinforcement is made of alkali-resistant glass fibres. Three samples were made of cement matrix and nine samples were made of cement matrix reinforced textile reinforcement (three of each type of reinforcement). The samples were tested in special attachment in one-axial tensile. Experimental tests were controlled by speed of rate of deformation (0.0005 m/min). The textile reinforcement has very good influence to behaviour of the textile reinforced concrete in tensile stress.

Abstract:

Abstract Textile reinforced concrete (TRC) is an eco-friendly material with a high freedom in design. As soon as complex curved parts are to be designed, the question of the drapability of the reinforcing materials arises. Different process parameters can be modified in the production of the reinforcing textiles which strongly influence the handling and the draping behaviour. To be able to choose a textile structure in the design stage which fulfils the requirements concerning drapability, a new test method was developed. This article describes this test method and shows results of a test series on different textile structures, including a brief discussion of the results. Finally, a transfer to a sample geometry is shown.

Abstract:

The bond between the textile reinforcement and the finegrade concrete (cementitious matrix) is essential for the structural behavior of textile reinforced concrete. The analysis of the bond behavior between roving and matrix is important for the development of computational methods analyzing textile reinforced concrete. Therefore, the pullout phenomenon of a roving from a matrix is investigated by analytical methods based on the implementation of various damage models for the interface.

Abstract:

Mechanical property and constraint mechanism of concrete cylinders confined by TRC under uniaxial compression is analyzed. 24 concrete cylinders confined by TRC and 8 unconfined concrete cylinders are loaded under uniaxial compression to investigate the performance based on textile ratio, section dimension and strength of concrete. Based on the test results, stress process and failure mechanism of strengthened members is studied, stress-strain relationship of strengthened members is researched, effect of ratio of textile reinforcement, section dimension and concrete strength on ultimate strength of strengthened members is also evaluated. The results show strengthened members showed increasing in strength and deformation. Strengthened members showed drum-shaped shear damage. With the increasing of textile ratio, the confining effect of TRC on the concrete increases. With the increasing of section dimension, the confining effect of TRC on the concrete decreases. The confining effect of TRC on low strength concrete is stronger.

Abstract:

To study the effect of various axial compression ratios on the seismic behavior of reinforced concrete (RC) columns strengthened with textile-reinforced concrete, in this study, an RC column model is established using the finite element analysis software, ABAQUS. This model’s seismic performance under earthquakes is investigated, and the numerical analysis results of the two test pieces are compared with the test results to verify the correctness of the model. The results show that the initial stage of RC loading is under the three-way restraint of the axial force and textile-reinforced concrete material. The yield load and peak load of the textile-reinforced concrete–strengthened RC column increase with the increase in the axial compression ratio. However, the increase in the axial pressure during the loading process accelerates the crack development. The displacement ductility coefficient and the energy dissipation capacity of the specimen are reduced as the axial compression ratio increases. The numerical calculation results of the textile-reinforced concrete–strengthened RC column are in good agreement with the experimental results, indicating that the numerical model based on ABAQUS is reasonable.

Abstract:

The article deals with lightweight concrete with non-conventional reinforcement and its application in thin-walled structures. As part of experimental research, several sets of thin-walled slab and complementary specimen were made to determine the material characteristics of lightweight concrete. The porous aggregate Liapor was used in the recipe. Two-dimensional carbon and 3D glass textiles were used as reinforcement. The impact study of different casting technologies and recipe on the material characteristics of lightweight concrete was included in the research. Fresh concrete for the slab production was placed in special wooden molds. The slabs were concreted in vertical and horizontal position. The casting method has a significant impact on the element material characteristics. Reinforced specimens have shown high strength, even in thin-walled structures with low bulk density.

Abstract:

In this study, a self-compacting high-strength concrete based on ordinary and sulfate-resistant cements was developed for use in textile-reinforced structural elements. The control concrete was made from quartz sand and tap water, and the sea concrete was made from sea water and sea sand for the purpose of applying local building materials to construction sites in the coastal area. The properties of a self-compacting concrete mixture, as well as concrete and textile-reinforced concrete based on it, were determined. It was found that at the age of 28 days, the compressive strength of the sea concrete was 72 MPa, and the flexural strength was 9.2 MPa. The compressive strength of the control concrete was 69.4 MPa at the age of 28 days, and the flexural strength was 11.1 MPa. The drying shrinkage of the sea concrete at 28 days exceeded the drying shrinkage of the control concrete by 18%. The uniaxial tensile test showed the same behavior of the control and marine textile-reinforced concrete; after the formation of five cracks, only the carbon textile reinforcement came into operation. Accordingly, the use of sea water and sea sand in combination with a cement with reduced CO2 emissions and textile reinforcement for load-bearing concrete structures is a promising, sustainable approach.

Abstract:

Textile-reinforced concrete (TRC) is a composite material consisting of a concrete matrix with a high-performance reinforcement made of technical textiles. TRC offers unique mechanical properties for the construction industry, enabling the construction of lightweight, material-minimized structures with high load-bearing potential. In addition, compared with traditional concrete design, TRC offers unique possibilities to realize free-form, double-curved structures. After more than 20 years of research, TRC is increasingly entering the market, with several demonstrator elements and buildings completed and initial commercialization successfully finished. Nevertheless, research into this highly topical area is still ongoing. In this paper, the authors give an overview of the current and future trends in the research and application of textiles in concrete construction applications. These trends include topics such as maximizing the textile utilization rate by improving the mechanical load-bearing performance (e.g., by adapting bond behavior), increasing design freedom by utilizing novel manufacturing methods (e.g., based on robotics), adding further value to textile reinforcements by the integration of additional functions in smart textile solutions (e.g., in textile sensors), and research into increasing the sustainability of TRC (e.g., using recycled fibers).

Abstract:

Masonry is a traditional building system in most countries of the world, including France. However, in recent decades, earthquakes have caused significant damage to masonry structures. The possibility of using textile-reinforced concrete or fibre-reinforced polymers to strengthen masonry structures has been recently assessed. This article addresses the effectiveness of externally bonded composite materials, particularly those based on newly developed cementitious matrices, to strengthen masonry structures. Experimental tests were performed in a previous study on six masonry walls, five of which were strengthened on both sides with either textile-reinforced concrete or fibre-reinforced polymers. This experimental campaign has been supplemented to determine the mechanical properties of the materials involved in design models, and it is used to check the potential of analytical models to predict lateral strength. This study identifies the interests and the restrictions governing the use of traditional empirical design approaches (employed for fibre-reinforced polymer-strengthened walls) when next-generation textile-reinforced concrete composites are used as strengthening materials. Adjustments taking into account the specificities of textile-reinforced concrete behaviour have been introduced, and their impact on the relevance of the models has been quantified.
