Experimental Study on Hybrid Fiber Reinforced Composites using Waste Fibers

Abstract

 Concrete is a brittle material. Concrete can withstand high compression load but fails to withstand the tensile load. Therefore concrete is generally good in compression whereas bad in tension. The split tensile of concrete is increased by adding steel fibers in volume fraction. However the plastic micro cracks in concrete cannot be elimination. The hybrid composite fiber-reinforced concrete was developed in order to obtain these properties and also to reduce the cost of fibers used. The process of making concrete with more than one fiber is known as hybrid fiber reinforced concrete. In this work, steel fibers, nylon, and coir are used for the analysis of at different fiber combinations such as steel and coir, steel and nylon, nylon and coir as reinforcement for making concrete with high strength. The strength characteristics are analyzed by studying the mechanical properties of the different fiber mix combinations.
