Bendable Concrete also known as Engineered Cementitious Composites abbreviated as ECC is class of
ultra-ductile fiber reinforced cementitious composites, characterized by high ductility and tight crack width control.
ECC is capable to exhibit considerably enhanced bendability because of its high capacity to store strain energy. It is
reinforced with micromechanically designed polymer fibers which gives it higher flexibility. The aim of this study is to
investigate the hardened property (i.e. Flexural Test) of ECC by addition of both PVA and Steel fibers in different
proportion. In this study, four different combinations of PVA and Steel fiber used to find out the better combination for
getting the higher elastic properties. The result of Flexural strength of various ECC mix with different percentage of
fibers are compare with Conventional Concrete design according to Indian Standard. All beams were tested under fourpoint loading test at different age in U.T.M.
