“…The flexural testing results of TRC samples at ambient conditions were listed in Table 3. The ultimate and first crack flexural stress of the TRC samples was calculated using the following Equation (1) [7]. The ultimate flexural load was observed when the bottom-most textile layer was subjected to rupture.…”

“…The use of Textile Reinforced Concrete (TRC) is increasing in recent years due to its superior properties, such as its excellent load-bearing capacity, high durability, fire-resistant nature, high corrosion resistance, and its various applications in construction [1][2][3][4][5][6]. A variety of materials can be used as textiles, including more common materials, such as carbon fiber, basalt fiber, and glass fiber [1,7]. As concrete cover required for the TRC is low due to the high corrosion resistance of the textile, TRC members can be fabricated with thinner sections compared to the conventional steel-reinforced sections [8,9].…”

“…A significant linear correlation was also observed between the reinforcement percentage of TRC and ultimate tensile and flexural strengths in the range of 0.5%-2% reinforcement percentages. Du et al [7] performed a four-point bending test to investigate the effect of the number of basalt textile layers, the percentage of steel short fibers, and the pre-stress level of the basalt textile layer on the flexural strength of the TRC. With increasing the number of textile layers from one to five, the flexural strength and toughness of the TRC have improved.…”

Textile Reinforced Concrete (TRC) is a prefabricated novel lightweight high-performance composite material that can be used as a load-bearing or non-load-bearing component of prefabricated buildings. Making TRC with Ultra-High-Strength Concrete (UHSC) (≥100 MPa) can be considered as a potential improvement method to further enhance its properties. This paper investigated the performance of Ultra-High-Strength Textile Reinforced Concrete (UHSTRC) under flexural loading. A detailed experimental program was conducted to investigate the behavior of UHSC on TRC. In the experimental program, a sudden drop in load was observed when the first crack appeared in the UHSTRC. A detailed analytical program was developed to describe and understand such behavior of UHSTRC found in experiments. The analytical program was found to be in good agreement with the experimental results and it was used to carry out an extensive parametric study covering the effects of the number of textile layers, textile material, textile mesh density, and UHSTRC thickness on the performance of UHSTRC. Using a high number of textile layers in thin UHSTRC was found to be more effective than using high-thickness UHSTRC. The high modulus textile layers effectively increase the performance of UHSTRC.

Normal concrete is weak against tensile strength, has low ductility and also insignificant resistance to cracking. The addition of diverse types of fibers at specific proportions can enhance the mechanical properties as well as the durability. Discrete fiber, which is commonly used, have many disadvantages such as balling the fiber, random distribution, and limitation of the used Vf ratio. Based on this vision, a new technique was discovered, enhancing concrete by textile-fiber to avoid all the problems mentioned above. This paper presents all important consequence and conclusions obtained from previous studies on how to strengthen concrete with two-dimensional and three-dimensional textile-fibers, and focuses on the flexural behavior of concrete members. The results indicate that there was an improvement in flexural strength, deformation capacity, and toughness with different load conditions when using different types of textile-fiber. It was observed that the effect of textile-fibers would increase when this fiber was coated by epoxy. In TRC system, there is a significant impact on the number of textile-fiber layers used.

In this paper, the effect of macro nonmetallic fibers (i.e., polypropylene fibers and basalt fibers) on the impact response of basalt fiber‐reinforced polymer‐reinforced concrete (FRP‐RC) discs is experimentally investigated using a self‐developed drop‐weight impact test device. The plain concrete and conventional steel‐reinforced concrete samples are explored as references. The impact resistance and failure behaviors are analyzed. Statistical analyses for first‐crack strength and failure strength are performed. The composite effect of basalt FRP bars and macro nonmetallic fibers on the impact energy at failure is also compared. The results indicate that the behaviors under impact load, that is, failure strength, crack number, the indent diameter, and penetration depth of the shriveled area, are greatly improved by adding of macro nonmetallic fibers, in particular macro polypropylene fibers. Additionally, the incorporation of these fibers into the basalt FRP‐RC transforms the brittle failure mode into a well ductile failure mode. Two‐parameter Weibull models are fitted by graphical methods and used to characterize the first crack strength and failure strength distributions. Reliability functions for first crack strength and for failure strength are estimated and failure strength can be predicted from first‐crack strength by using a linear regress model. The hybrid use of basalt FRP bars and macro nonmetallic fibers demonstrates a positive synergetic effect on the impact energy at failure.
