“…20 Chain length has a significant influence on key performance metrics such as tensile strength, viscosity, and flexibility. 29 Bahraq et al 30 demonstrated that polyethylene (PE) and PVA improve the tensile strength and crack bridging capability of cement-based composite materials (ECC) through strain hardening behavior. F. Pelisser et al , 31 through XRD analysis, discovered that the addition of PVA increases the interlayer spacing of the C–S–H matrix, indicating the potential of low molecular weight PVA to embed within the C–S–H matrix.…”

“…Moreover, PP fiber has better durability when exposed to an alkaline environment due to the fact of its hydrophobic and non-polar nature [32]. Despite the advantages offered by adding fibers in ECC compositions, some drawbacks, such as a reduction in compressive strength, and an increase in shrinkage and porosity were reported for excess use of fibers [33]. Virgin PE fiber has low mechanical bonds, and they are vulnerable to degradation in the alkaline concrete environment [34][35][36].…”

Engineered cementitious composite (ECC) is a new generation of fiber-reinforced concrete with high ductility and exceptional crack control capabilities. However, ECC can suffer a substantial reduction in ductility when exposed to elevated temperatures resulting in a loss of crack-bridging ability. In this study, the effect of adding basalt fiber (BF), which is an inorganic fiber with high-temperature resistance for the production of ECC, was studied. Moreover, the change in the mechanical properties of ECC, including compressive, tensile, and flexural strength, was experimentally investigated under elevated temperatures up to 400 °C. The results showed that the addition of BF to reinforced ECC improved the tensile and flexural strength of concrete effectively, but compressive strength marginally decreased. A significant decrease was observed in the range from 300 to 400 °C, while it increased smoothly when heated up to 300 °C. The compressive and flexural strength diminished after a slight strain gained when heated up to 100 °C. This work paves the way for future investigations focusing on the development of high-temperature resistance ECC.

“…Furthermore, using supplementary cementitious materials (SCMs) such as fly ash (FA), slag (SL), silica fume (SF), metakaolin (MK), limestone powder (LM), nano silica (NS), and others is strongly advised to enhance the qualities of RAC [19][20][21]94].…”

Using recycled concrete aggregates from construction and demolition wastes on structural concrete is a sustainable solution to reduce the consumption of natural resources and the detrimental effects of concrete production on the environment. This paper has collected much data from the literature to study fresh, mechanical properties and durability of concrete made of treated/untreated recycled aggregate (RA). Furthermore, the flexural and shear behavior of recycled aggregate concrete (RAC) beams was studied. This study discussed the distinctions and similarities between reinforced RAC beams and reinforced natural aggregate concrete (NAC) beams. The results of this review’s analysis clearly show that reinforced RAC beams with different RAC ratios perform structurally on par with or slightly worse than reinforced NAC beams, demonstrating the viability of RAC for structural applications. Emphasis is placed on carefully choosing and adjusting material models for recycled aggregate concrete. Ultimately, guidelines for future inquiries in this field are delineated and deliberated upon. The review will be advantageous for academics and professionals who aim to acquire a comprehensive comprehension of the behavior of RAC beams. It addresses several practical concerns connected to the numerical modeling of these components, which have not been adequately covered in existing literature.
