Abstract
The paper deals with the Experimental Investigation on Influence of Polypropylene Fiber on Strength parameter of concrete (M40). Conventional concrete has two major drawbacks low tensile strength and brittle failure. Fiber reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. In an attempt to increase concrete ductility and energy absorption. Polypropylene fiber is a light weight synthetic material. It prevents crack formation and provides reinforced to the concrete structure. An experimental investigation explored properties such as compressive strength, flexural strength, spilt tensile strength and shear strength of polypropylene fiber reinforced concrete. Polypropylene fiber with 12mm length and five volume fractions of 0%, 0.5%, 0.75%, 1%, 1.25%, 1.5% are used.
