Abstract
Bendable concrete is one of the emerging term nowadays which is also called as ECC (Engineered Cementitious Composites) developed by Dr. Victor C. Li in 2001. Compressive strength of concrete is comparatively very high than tensile strength. But for the resistance to unknown tensile forces due to reversal of stresses as in case of earthquakes is the normal concrete fails catastrophically. Newly developed ECC is having higher tensile strength with same compressive strength. Cost of ECC is comparatively high than normal concrete due to the presence of PVA, (Polyvinyl Alcohol Fibers). The main aim was to study the change in the original properties of ECC with the partial replacement of conventional cement with the slag sand. The study was done on both compressive strength and split tensile strength after 7 days and 28 days of curing. The cement in the ECC was replaced by slag sand, that is waste from iron industry in the percentage of 10, 20, and 30 by weight of cement.
