“…The 20 mm specimen thickness was chosen to simulate thin TRC element. The selection of the span-to-depth ratio is congruent with the literature [ 8 , 66 , 67 , 68 ]. The span-to-depth ratio selected is also suitable given the relatively high deformations reported for TRC specimens and since most of the TRC applications are for shell-like structures [ 1 , 2 , 6 , 7 , 24 ].…”

“…For this to happen, the specimen needs to crack, and thus no reinforcement contribution is provided prior to the first-crack state. Other researchers reported on this phenomenon [ 8 , 68 ]. Nevertheless, the post-peak behavior, after cracking, is significantly improved as the textile reinforcement carries the tension stresses and allows the TRC composite to continue carrying load as shown in Figure 5 .…”

Flexural Behavior of a Novel Textile-Reinforced Polymer Concrete

Textile reinforced concrete (TRC) has gained attention from the construction industry due to its light weight, high tensile strength, design flexibility, corrosion resistance, and remarkably long service life. Some structural applications that utilize TRC components include precast panels, structural repair, waterproofing elements, and façades. TRC is produced by incorporating textile fabrics into thin cementitious concrete panels. Premature debonding between the textile fabric and concrete due to improper cementitious matrix impregnation of the fibers was identified as a failure-governing mechanism. To overcome this performance limitation, in this study, a novel type of TRC is proposed by replacing the cement binder with a polymer resin to produce textile reinforced polymer concrete (TRPC). The new TRPC is created using a fine-graded aggregate, methyl methacrylate polymer resin, and basalt fiber textile fabric. Four different specimen configurations were manufactured by embedding 0, 1, 2, and 3 textile layers in concrete. Flexural performance was analyzed and compared with reference TRC specimens with similar compressive strength and reinforcement configurations. Furthermore, the crack pattern intensity was determined using an image processing technique to quantify the ductility of TRPC compared with conventional TRC. The new TRPC improved the moment capacity compared with TRC by 51%, 58%, 59%, and 158%, the deflection at peak load by 858%, 857%, 3264%, and 3803%, and the toughness by 1909%, 3844%, 2781%, and 4355% for 0, 1, 2, and 3 textile layers, respectively. TRPC showed significantly improved flexural capacity, superior ductility, and substantial plasticity compared with TRC.

“…Recently, several researchers have performed experimental and theoretical studies on the TRC flexural component [6,7,8,9]. Co-working among the filaments of the textile is significantly improved after impregnation of textiles with polymers, but the impregnated textiles are easily separated from the matrix.…”

Four-point bending tests were adopted to investigate the influences of the number of textile layers, volume content of steel fibres, and prestress on the flexural behaviour of carbon textile-reinforced concrete (TRC). The failure mode of the specimen changed from debonding failure to shear failure, accompanied by the matrix-textile interfacial debonding with an increasing number of textile layers. The interfacial bonding performance between the textile and matrix improved with the addition of steel fibres in the TRC specimens. The presence of prestress or steel fibres improved first-crack and ultimate stresses of the TRC specimen. In comparison with the first-crack stress, a more pronounced enhancement in the ultimate stress was achieved by the addition of steel fibres. However, the effect of prestress on the first-crack stress was found to be more significant than on the ultimate stress. The prestress combined with steel fibres further improved the flexural behaviour of the TRC specimens. The prestressed TRC specimens with 1% volume content of steel fibres effectively avoided debonding. Thus, the utilization of the textiles could be improved.

“…In the literature, there were several numerical studies on the mechanical behavior of TRC composite materials. Portal et al [4] presented 2-D modeling of the flexural behavior of a carbon TRC thin plate specimen. In this research, the sensitivity of the contact perimeter between carbon textile yarns and cementitious matrix was investigated thanks to a parametric study by modifying the ratio between the width and the thickness of the rectangular perimeter.…”

A big question in the numerical approaches for the mechanical behavior of the textile-reinforced concrete (TRC) composite under tensile loading is how to model the cracking of the cementitious matrix. This paper presents numerical results of 3-D modeling of TRC composite in which the non-linear behavior model was used by considering the cracking for the cementitious matrix. The input data based on the experimental results in the literature. As numerical results, the TRC composite provides a strain-hardening behavior with three phases in which the second one is characterized by the drops in stress on the stress-strain curve. Furthermore, this model could show the failure mode of the TRC specimen with the multi-cracking on its surface after the numerical tests. From this model, the development of a crack from micro-crack to macro at a cross-section was highlighted. The stress jumps in reinforcement textile after each crack was also observed and analyzed. In comparison with the experiment, a good agreement between both results was found for all cases of this study. A parametric study could show the effect of the length and position of the measurement zone on the stress-strain curve of TRC’s mechanical behavior.
