The results showed that the average ultimate tensile strain of SHCC was 403 times that of ordinary concrete, and the peak compressive strain was about four times higher than ordinary concrete. In addition, the double-edge notched plate specimens with relative notch lengths of 0.2, 0.4, and 0.6, respectively, were tested. The tensile test on the thin-plate specimen and compression test on cylindrical specimen were carried out. Testing variables included water/binder ratio, sand/binder ratio, fly ash and cement content, and sand particle. ![]() In this study, 10 groups of SHCC were developed by incorporating polyvinyl alcohol (PVA) fiber into cement-based materials with high-content fly ash. ![]() ![]() SHCC has the characteristics of strain hardening and multiple cracking under tensile load. The emergence of strain-hardening cementitious composites (SHCCs) improves brittle cracking of concrete materials.
