Abstract
In modern construction infrastructure development is highly improved. The engineered cementitious composites (ECC) are high ductile and flexural property are used to improve the load carrying capacity of the concrete. Polyvinyl alcohol (PVA) fiber can be used as a better convenient material for ECC and more quantity of PVA can be produced yearly around 650,000 tons per year. It can be used in cement-based composite materials as many ways. For achieving balanced composite performance, the design procedure of PVA is more requirable for structural applications and practical design consideration. PVA gives a positive results in terms of micro structure behavior the formation of Ca(OH)2 were found to be reduced which contributes to better adhesion between the paste and the aggregates. A ductile fiber-reinforced cementitious composite (DFRCCs) investigates the effects of freeze-thaw cycles, and water-to-binder ratio as well as reinforcing fiber combination on flexural properties and cracking procedure of DFRCC prismatic specimens. The DFRCC determined from the results of durability test such as Dynamic Modulus of elasticity, Toughness Index, Mass loss.
