A STUDY ON FIBER REINFORCED CONCRETE WITH FLY ASH

Abstract

Today's world is observing the construction of very challenging and enormous civil engineering structures. But the concrete has only material is called upon to possess very high strength and the very sufficient work ability in the properties. Thus Researchers of the world are attempting to develop the high performance in concretes by using fibers and other of the admixtures in concrete up to certain limitations in the calculations. The has been high interest in the use of the fibers for the reinforcement of composites has increased during the couple several years. Also combination of the high strength also stiffness and the thermal resistance favorably characterizes thus the fibers are being used in this project.

Hence Polypropylene Fiber Reinforcement Concrete is embryonic .construction material who is can be described of having. The high mechanical strength, durability stiffness. By then utilization of PPF has the very concrete not only optimum utilization of materials is achieved but also the finances & costs are reduced.

A study on polypropylene fiber reinforced concrete with replacement of fly ash has been studied. M25 grade concrete is designed and fibers are mixed in varying percentage i.e., 0.5%,1%,1.5%,2%,2.5%, 3%. Fly ash also added with different percentage i.e., 10%,15% and 20%. Concrete cubes of size 22350 mm3 are casted and cured for twenty eight days and then tested for compressive strength in the test machine used.
