Abstract:

The fire remains one of the serious potential risks to most buildings and structures, as recently it’s been witnessed in Paris’ historic Notre Dame Cathedral and London’s Grenfell Tower. Concrete and masonry construction materials suffer physiochemical changes and mechanical damage caused by heating that is usually confined to the outer surface but can eventually compromise their load-bearing capacity. FRCM systems could provide when applied, supplemental fire insulation on pre-existing structural members, but there is a lack of knowledge about their properties in those conditions. This experimental work, thus, aims to evaluate the mechanical behaviour of carbon-FRCM and basalt-FRCM composites bonded to masonry substrate after high temperature exposure. Temperatures of 100 °C, 300 °C and 500 °C over a period of three hours were used to investigate the degradation of their mechanical properties. Single lap shear bond tests were carried out to evaluate the bond-slip response and failure modes. For all the tested temperatures higher peak stresses were measured for carbon-FRCM composite than basalt ones. Furthermore, low-density basalt-FRCM composite showed higher peak stresses and lower global slips up to 300 °C than high-density one. Carbon-FRCM composite failure mode was not effected by temperature. High-density basalt-FRCM composite showed a change in failure mode between 300 °C and 500 °C.

Abstract:

Abstract.The paper is devoted to the analysis of the effectiveness of the Carbon Fiber Reinforced Cementitious Matrix (C-FRCM) as confinement system of the masonry and the characterization of the structural response of masonry column confined by C-FRCM jackets, accounting for all geometrical and mechanical involved parameters. At this aim, tests on confined masonry column under eccentric axial load were carried out. Five masonry column having an overall length of650 mm, with rectangular cross-section,250 x250 mm, were eccentrically loaded until collapse; two specimens were un-confined and used as control specimens, two specimens were confined with one layer of C-FRCM and one specimen was confined with two layers of C-FRCM. The eccentricity values considered weree/H=0ande/H=0.20, being H the height of the section. Failure modes and load-strain diagrams were considered to analyze test results and to evaluate the effectiveness of the confinement both in terms of strength and ductility.

Abstract:

Deep learning has been well-known for a couple of years, and it indicates incredible possibilities for unsupervised learning of representations with the clustering algorithm. The forms of Convolution Neural Networks (CNN) are now state-of-the-art for many recognition and clustering tasks. However, with the perpetual incrementation of digital images, there exist more and more redundant, irrelevant, and noisy samples which cause CNN running to gradually decrease, and its clustering accuracy decreases concurrently. To conquer these issues, we proposed an effective clustering method for a large-scale image dataset which combines CNN and a Fuzzy-Rough C-Mean (FRCM) clustering algorithm. The main idea is that first a high-level representation, learned by multi-layers of CNN with one clustering layer, produce the initial cluster center, then during training image clusters, and representations, are updating jointly. FRCM is utilized to update the cluster centers in the forward pass, while the parameters of proposed CNN are updated by the backward pass based on Stochastic Gradient Descent (SGD). The concept of the rough set of lower and boundary approximations deal with uncertainty, vagueness, and incompleteness in cluster definition, and fuzzy sets enable efficient handling of overlapping partitions in the noisy environment. The experiment results show that the proposed FRCM based unsupervised CNN clustering method is better than the standard K-Mean, Fuzzy C-Mean, FRCM and also other deep-learning-based clustering algorithms on large-scale image data.

Abstract:

In the last decade a re-discovering of the construction techniques and materials belonging to ancient buildings and heritage has grown up.Professionals and researchers have made a strong effort to understand resisting mechanisms in masonry buildings, trying to evaluate the safety factor in presence of vertical and horizontal seismic loads. As a consequence, innovative techniques and materials, as the FRCM, have been introduced to prevent local and global collapse mechanism, increasing the safety of the overall structure.The special cases of “Duomo of Colorno” and the “Braidense Library”, in Italy, are here presented.The XVIII century masonry vaults of the Duomo widely suffered due to a seismic event occurred in 2012 and a relevant crack pattern appeared.A similar situation occurred for the barrel vault of the Braidense Library due to settlement of foundations.In both cases, in order to restore the global resistance of the building, some consolidation interventions have been proposed.One of those is represented by a FRCM net applied on the upper side of the vaults. The system makes use of a carbon bi-directional fiber net inserted in an inorganic pozzolanic matrix, fully compatible with the ancient masonry support.A numerical non-linear analysis of the cathedral and of the barrel vault of the Braidense Library has demonstrated an increment up to 25% in the value of the horizontal loads that cause the formation of the first cracks, if compared with the non-consolidated situation.Furthermore, besides this passive fiber intervention, an innovative active technique called “RAM – Reinforced Arch Method” was applied on the vaults of the Duomo. The use of post-tensioned steel cables, added to the FRCM net, led to a strong increase of the horizontal collapse load.Carbon fibers are able to induce a strong increase in the resistance of the masonry under the tensile stresses caused by seismic loads, avoiding the formation of cracks or plastic hinges.Several tests have been performed on FRCM, according to Standards.In tensile and lap-tensile strength tests, the stress-strain behavior of C-FRCM control coupon specimens is bi-linear as expected. The initial branch of the curve corresponds to the un-cracked specimen, followed by a second branch with a reduced slope, corresponding to the crack specimen.The primary failure mode of the C-FRCM coupon specimens was slippage of the fibers after multiple cracking throughout the length of the specimen, perpendicular to the direction of the load, secondary de-bonding failure mode located at the tab ends was observed in some cases.Furthermore, all tensile and lap-tensile strength coupon tests passed the conditions of acceptance as per the requirements regarding environmental exposure to Freezing and Thawing, and Aging.

Abstract:

In this paper, the behavior of corroded hollow section RC (reinforced concrete) columns strengthened by an Impressed Current Cathodic Protection and Structural Strengthening (ICCP-SS) system was investigated. The Carbon Fabric-Reinforced Cementitious Matrix (C-FRCM) composite serves dual functions in the intervention method. The axial compression behavior of strengthened columns was firstly investigated through axial compression tests. The influence of corrosion ratio and C-FRCM strengthening on the test results, such as failure mode, load–displacement curve, ultimate load, and ultimate strain, were analyzed. Test results showed that the ultimate load of the corroded specimens could be enhanced significantly by C-FRCM, and the ductility of the strengthened specimens was larger than the specimens without strengthening, especially for the specimens with higher corrosion ratios. Secondly, the effects of the ICCP-SS system on the migration and distribution laws of chloride ions (Cl−) in hollow section RC columns were analyzed by the potentiometric titration method. The main parameters include charging time, current density, and salt addition. Results showed that the rebar would have a certain blocking effect on the migration of Cl−, which resulted in that the content of Cl− in the inner side of the rebar was always larger than that of the outer side; and research results also showed that the increase of impressed current density and charge time would reduce the Cl− content on both sides of the rebar, while the impressed current would cause the Cl− near the rebars to constantly move toward the vicinity of CFRP.

Abstract:

The application of the elasto-plastic material model known as the Barcelona Model (BM) for numerical assessment of a historical vault subjected to earthquake sequence is presented in this work. As a case study, part of a masonry vault erected in Southern Poland in the 12th century was chosen. For the study purposes, a 3D finite element model (FEM) of the vault was prepared using the ABAQUS/Standard software program. The essential details of the structure geometry were taken from the 3D scan of the vault. The first variant of the masonry vault was the structure without any strengthening, whereas the second variant was with strengthening system realized by application on composite materials, i.e., the carbon fiber reinforced cementitious matrix (C-FRCM). The results of the dynamic analysis revealed that an evident nonlinear performance of the masonry materials of the vault in both cases was detected for both FE models of the structure. The analysis proved that the foreshock–mainshock–aftershock sequence caused substantial damages in structural parts of the masonry vault. The distribution of plastic strains and damages allowed assessment of the impact of the full seismic sequence on the masonry vault. In the case of the unstrengthen vault the level of cracking and stiffness loss reached 90%. In the case of the vault strengthened with the FRCM system the tensile damage level was significantly lower. It did not exceed 30%. In addition, the first plastic zone of the unstrengthened masonry structural elements of the vault became visible after the foreshock.

Abstract:

This paper presents a number of case studies related to the strengthening of concrete and masonry structures damaged by the April 6, 2009, Mw 6.3 earthquake that struck the Italian city of L’Aquila and surrounding localities. After a brief overview of the existing challenges in buildings constructed prior to 1972 when the first building code addressing seismic construction was enacted in Italy, the paper describes interventions using technologies that can be considered innovative in that they are not addressed in the majority of the current building codes worldwide. The following strengthening methods are described: a) fiber-reinforced polymer (FRP) composites in the forms of manual lay-up, procured laminates and spikes; b) steel-reinforced polymer (SRP) lay-up and spikes; and, c) fabricreinforced cementitious matrix (FRCM). The paper concludes with a description of how the deployment of innovation for construction takes place in the United States. This example is intended to identify challenges to innovation and a possible method to overcome them.

Abstract:

Miracidium is the first larval stage emerging frcm the egg produced in the vertebrate host in the life cycle of a Schistosome. They have to find a particular species of snail (the Intermediate host) within few hours for the continuation of the life cycle of the parasite and for which they have to be well equipped. Cilia helps them in the movement and sensory organs aid in locating the host. Some cytolytic substance producing glands helps in their penetration into the host.Miracidia were obtained from livers of mice infected 2 months previously with cercaria of Schistosoma japonlcum, in the Department of Microbiology, University of Chicago, Chicago, USA. The Miracidia were fixed in freshly prepared 6% Glutaraldehyde in 0.2 M phosphate buffer at pH 7.6 at 4°C for 2 hr. and were post fixed for 1 hr. in 1% Os O4 in the same buffer. They were washed twice with double distilled water and dehydrated in graded series of ethanol.

Abstract:

The main objective of this article is to describe the influence of hydrothermal curing conditions in an autoclave device (different pressure and temperature), which took place at various ages of a fresh mixture (cement matrix – CM, and fibre-reinforced cement matrix – FRCM), on textile reinforced concrete production. The positive influence of autoclaving has been evaluated through the results of physical and mechanical testing – compressive strength, flexural strength, bulk density and dynamic modulus of elasticity, which have been measured on specimens with the following dimensions: 40×40×160mm<sup>3</sup>. In addition, it has been found that increasing the pressure and temperature resulted in higher values of measured characteristics. The results indicate that the most suitable surrounding conditions are 0.6MPa, and 165 °C at the age of 21 hours; the final compressive strength of cement matrix is 134.3MPa and its flexural strength is 25.9MPa (standard cured samples achieve 114.6MPa and 15.7MPa). Hydrothermal curing is even more effective for cement matrix reinforced by steel fibres (for example, the compressive strength can reach 177.5MPa, while laboratory-cured samples achieve a compressive strength of 108.5MPa).

Abstract:

The research aimed to determine the tensile bond strength (TBS) between polymerized intact and ground fiber-reinforced composite (FRC) surfaces. FRC prepregs (a reinforcing fiber pre-impregnated with a semi-interpenetrating polymer network (semi-IPN) resin system; everStick C&B) were divided into two groups: intact FRCs (with a highly PMMA-enriched surface) and ground FRCs (with a low PMMA gradient). Each FRC group was treated with: StickRESIN and G-Multi PRIMER. These groups were further divided into four subgroups based on the application time of the treatment agents: 0.5, 1, 2, and 5 min. Next, a resin luting cement was applied to the FRC substrates on the top of the photo-polymerized treating agent. Thereafter, weight loss, surface microhardness, and TBS were evaluated. Three-factor analysis of variance (p ≤ 0.05) revealed significant differences in the TBS among the FRC groups. The highest TBS was recorded for the intact FRC surface treated with G-Multi PRIMER for 2 min (13.0 ± 1.2 MPa). The monomers and solvents of G-Multi PRIMER showed a time-dependent relationship between treatment time and TBS. They could diffuse into the FRC surface that has a higher PMMA gradient, further resulting in a high TBS between the FRC and resin luting cement.

Abstract:

Los materiales compósitos formados principalmente por fibras de carbón y matrices de resinas poliméricas epoxi han sido utilizados por más de 30 años, alcanzando un alto nivel técnico en todo el mundo. A pesar de los extraordinarios resultados obtenidos con este tipo de resinas, algunas de sus características han sido fuertemente criticadas, teniendo como consecuencia algunas limitaciones en su aplicación y en la definición de soluciones de diseño. Las restricciones de las aplicaciones de las tecnologías basadas en resinas epoxi se deben principalmente a su ausencia de permeabilidad a la humedad, su alta sensibilidad a la humedad durante la aplicación, sus escasas propiedades térmicas con un valor de T.g. de 100 °C y su falta de resistencia a la quema.En nuestra empresa Ardea, hemos llevado a cabo una larga investigación sobre este tema y hemos introducido en el mercado de la construcción un nuevo sistema de resinas a base acuosa, Betontex IPN, los cuales están basados en estructuras poliméricas interpenetradas. Betontex IPN es un sistema de resinas de dos componenes: el Componente A es una sustancia polimérica emulsionada en agua y el Componente B es una segunda fase polimérica presente en un relleno inorgánico microcristalino. Después del mezclado e homogenizado, el material resultante es permeable a la humedad y resistente a la quema (de acuerdo a la normativa UNI 9177), con una resistencia térmica más allá de los 180 °C y una temperatura de degradación mayor a 600 °C.Las propiedades de éstas resinas en combinación con refuerzos de fibras de carbón, aramida y vidrio han sido evaluadas en estructuras de mampostería y concreto. Las resinas IPN muestran una gran gama de propiedades interesantes y pueden ser usadas como tecnología FRP en lugar de las resinas epoxi, o como tecnología FRCM, en donde el IPN actúa como promotor de adhesión entre las fibras y el mortero. Otras propiedades de las resinas IPN incluyen buenas propiedades mecánicas, buena adhesión a las fibras, alta compatibilidad y buena adhesión a morteros de cal, concreto, mampostería, madera y mármol. El sistema de resinas IPN puede también ser usado en condiciones húmedas y aplicado sobre superficies mojadas. En los últimos años, las nuevas tecnologías IPN han sido ampliamente usadas para la rehabilitación de estructuras dañadas como consecuencia de los terremotos de 2009 (L’Aquila, Italia) y 2012 (Emilia Romagna, Italia).

Abstract:

The use of synthetic fibers in fiber-reinforced concretes (FRCs) is often avoided due to the mistrust of lower performance at changing temperatures. This work examines the effect of moderate temperatures on the flexural strengths of FRCs. Two types of polypropylene fibers were tested, and one steel fiber was employed as a reference. Three-point bending tests were carried out following an adapted methodology based on the standard EN 14651. This adapted procedure included an insulation system that allowed the assessment of FRC flexural behavior after being exposed for two months at temperatures of 5, 20, 35 and 50 °C. In addition, the interaction of temperature with a pre-cracked state was also analyzed. To do this, several specimens were pre-cracked to 0.5 mm after 28 days and conditioned in their respective temperature until testing. The findings suggest that this range of moderate temperatures did not degrade the behavior of FRCs to a great extent since the analysis of variances showed that temperature is not always a significant factor; however, it did have an influence on the pre-cracked specimens at 35 and 50 °C.

Abstract:

Conch shell bio-filler (CSBF) was prepared by washing, ultrasonicating, and pulverizing of conch shells and then was applied in waterborne intumescent fire-retardant coatings. The influence of CSBF on fire resistance and anti-ageing properties of intumescent fire-retardant coatings were studied by using different analytical methods. The fire protection and smoke density tests showed that when the mass fraction of CSBF was 3%, the resulting FRC3 coating had the optimum synergistic flame-retardant and smoke-suppression effects concomitant with a flame-spread rating of 10.7, equilibrium backside temperature of 152.4 °C at 900 s, and smoke-density rating value of 10.4%, which were attributed to the establishment of a more dense and stable intumescent char layer against heat and mass transfer. Thermogravimetric analysis indicated that the presence of CSBF increased the thermal stability and char-forming performance of the coatings, and the char residue of FRC3 rose to 34.6% at 800 °C from 28.6% of FRC0 without CSBF. The accelerated ageing test suggested that the incorporation of CSBF reduced the migration and decomposition of the flame retardants and the yellowing, blistering, and powdering phenomenon, thus improving the structural stability of the coating, resulting in better durability of flame retardancy and smoke-suppression performance.

Abstract Aim The aim of this study was to determine the compressive fatigue limits (CFLs) of fractured incisor teeth restored using either a conventional adhesive-composite technique or using fiber-reinforced composites (FRCs). Methods and Materials Fifteen extracted sound upper incisor teeth were prepared by cutting away the incisal one-third part of their crowns horizontally. The teeth were restored using three techniques. Group A (control group) was restored by reattaching the original incisal edge to the tooth. Group B was restored using particulate filler composite (PFC). Group C was restored with PFC and FRC by adding a thin layer of FRC to the palatal surface of the teeth. The bonding system used was a conventional etch system with primer and adhesive. All restored teeth were stored in water at room temperature for 24 h before they were loaded under a cyclic load with a maximum controlled regimen using a universal testing machine. The test employed a staircase approach with a maximum of 103 cycles or until failure occurred. Data were analyzed using analysis of variance (ANOVA) (p=0.05). Failure modes were visually examined. Results Group A (reattaching fractured incisal edge) revealed the lowest CFL values, whereas the creation of a new incisal edge with PFC revealed a 152% higher CFL value compared to Group A. Group C (teeth restored with FRC) revealed a 352% higher CFL than the control group. ANOVA revealed the restoration technique significantly affected the compressive fatigue limit (p<0.001). The failure mode in Group A and B was debonding of the restoration from the adhesive interface. While in Group C, the sample teeth fractured below their cemento-enamel junctions. Conclusion These results suggested an incisally fractured tooth restored with the combination of PFC and FRC-structure provided the highest CFL. Citation Garoushi SK, Lassila LVJ, Vallittu PK.

Abstract:

One of the growing demands in concrete manufacture is the availability of natural fine aggregates, which account for 35% to 45% of the total concrete. An alternative method of disposal of fine recycled concrete aggregates (FRCA) generated from demolition and construction waste (C&DW) is their usage in mortar and the development of recycled mortar. The main aim of this research work is to evaluate the viability of incorporating FRCA from urban C&DW for the manufacture of cement-based mortars. Simple processing techniques like washing and sieving are adopted to improve the FRCA quality. Physical and chemical characterization of ingredients is carried out. In total four mixes of 1:3 (cement: sand) mortar with partial replacement of normalized sand with FRCA (0%, 25%, 50%, and 100%) are evaluated for mechanical properties. Water to cement ratio for all four mortar mixes are determined by fixed consistency. Mechanical and physical properties like density, compressive strength, and flexural strength are studied for various curing periods, and the result is that the optimum usage of FRCA is 25% based on a 90-day curing period.

Abstract:

AbstractDetermination of shear-load-bearing capacity of reinforced concrete beams (according to the current normative documents), comprises particular recommended values, which do not depend on the parameters of the sample or load. This article describes the methodology for determination the shear strength with suggestions for calculation the coefficient CRd,c and compressed element tilt angle Ѳ while reinforced concrete elements` calculation with the use of “truss model”. In order to confirm the methodology 4 reinforced concrete beams were tested. Tests were performed in order to investigate each particular inclined section separately. Variable parameter was the relative shear span a/d, with its values a/d=2, a/d=1,5 and a/d=1. Another parameter was the usage of composite strengthening system, made for relative shear span a\d=2. Samples were tested as single-span beams subjected to short-term loading. The calculation with the use only the values, given in norms showed significant divergence of results. Using the refined parameter values provided the convergence of results within 16-29% toward overestimation of the experimental data. The composite reinforcement system calculation showed the overestimation of 23%, which is within the same limits as for the control samples.
