“…This character of the curves in Fig. 6 also appeared in the test data on steel fiber reinforced concrete previously reported by Yoo et al [17]. As stated in that study, matrix softening and fiber bridging effect dominates bending behavior when the first crack occurs.…”

This study investigated the effect of fiber ratio on the impact behavior of polypropylene fiber reinforced concrete cube and beam samples. Plain concrete mixtures for control samples and polypropylene fiber-reinforced concrete mixtures with fiber ratios of %0.22, %0.44, and %0.66 by volume were prepared. An instrumented drop-weight impact system was used for the dynamic tests. Static compression tests, three-point bending tests, and impact tests were performed on beam samples (with the dimension of 100×100×500 mm). Static compression and impact tests were performed on cube samples (with the size of 100 mm). It was observed that the fracture properties of polypropylene fiber reinforced concrete for both cube and beam samples were better than the control samples under impact. The crack width in the beams under the impact decreased with the increase in polypropylene fiber ratio. The cube and beam concrete samples reinforced with polypropylene fibers absorbed the impact energy better than the control samples.

“…This study showed that the usage of 3D-TF gives greater improvement in bending strength and toughness than 2D-TF. In the same time, the usage of 0.5 % of steel-fiber gives greater bending strength and toughness than both 3D-TF and 2D-TF [14].…”

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.

“…Besides, compared to specimens without steel fibers, the addition of steel fibers has higher static compressive strength. This is due to the fiber bridging against the further development of cracks (Yoo et al, 2016).…”

Concrete as the most commonly used construction material has high compressive strength; however, the main disadvantages associated with concrete are low tensile strength, low cracking resistance, and low ductility, etc. When concrete structures are subjected to dynamic loadings, such as earthquake, impact, and blast, catastrophic failure can occur, which is costly and also induce public risk. The strike of Twin Towers in New York by airplanes in 2001 terrorist attack is a typical example (Soe et al., 2013). Therefore, a proper understanding of the response of concrete material to dynamic loadings is very critical for designing structures correctly.Many researchers have adopted various ways to improve the dynamic behavior of ordinary concrete, of which engineered cementitious composites (ECC) and textile reinforced concrete (TRC) are two effective solutions (Heravi et al., 2020). Engineered cementitious composites (ECC) are ultra-ductile fiber-reinforced cement-based composites, which can provide extraordinary strain-hardening property and good toughness with ultimate tensile strain more than 3%, and also exhibit well in controlling the initiation and growth of cracks (Sakulich and Li, 2011;Kai et al., 2016). In ECC, the commonly used fibers include steel fibers, carbon fibers, polyvinyl alcohol (PVA) fibers, and polyethylene (PE) fibers, etc. Different fiber types can lead to varying reinforcement efficiencies. The high-modulus fibers (e.g., steel and carbon fibers) normally provide high ultimate strength but low strain capacity; however, the low-modulus fibers (e.g., PVA and PE fibers) exhibit the opposite behavior (Maalej et al., 2005). Kai et al. and Mechtcherine et al. indicated that the ECC reinforced with PVA is a strain rate sensitive material, and the strength, energy consumption, and strain at
