Abstract
The paper deals with the addition of various proportions of polypropylene fiber on the properties of High strength concrete (M25 mixes). An experimental program was carried out its effect of compressive, tensile, flexural strength. In this project the overall aim is to utilize and evaluate the performance of polypropylene fiber in the concrete. By the utilization of Polypropylene fiber in concrete not only optimum utilization of material is achieved but also the cost reduction is achieved. There also have been several advanced made in the development of fiber reinforced concrete to control cracking and to increase the overall ductility of the material. However, there are now many types of fibers with different materials and geometric properties, but the exact fracture behavior of fiber reinforced Concrete material is not clearly understood. Majorly, synthetic fiber has played a dominant role for a long time in a variety of applications for their high specific strength and modulus. The optimum percentage of polypropylene fiber in the concrete was found out with respect to cube compressive strength, flexural strength and spilt tensile strength at the age of 28days. The specimen was casted for different percentage such as 0.05%, 0.25%, 0.5%, and 0.75 (by volume fraction) by the mass of the concrete. The result of this present investigation indicates by adding 0.5% of polypropylene fiber show maximum compressive and tensile strength.
