TO STUDY THE EFFECT OF POLYPROPYLENE FIBER, FLY ASH AND RICE HUSK ON CONCRETE PROPERTIES

Abstract

India is a  developing country in world now a days. In future there will be a need of  high strength  and high performance concrete required for  the construction of  work .Fiber concrete  is concrete containing  fibrous material which increases its structural integrity. The character of fiber concrete changes with varying concretes fiber materials, geometries, distribution, orientation, and densities. Polypropylene fiber is a light weight synthetic fiber. It prevents crack formation and provides reinforcement to the concrete structure. In this project we are adding the different  percentage values of the polypropylene fibers such as  0%,0.5%, 1%, 1.5%,  2% values  and replacement of the cement by 10% of fly ash and rice husk each are added  in concrete. Tests on workability, compressive strength, split tensile strength and flexural resistance  were conducted on specimens.
