Strength Behaviour of M25 Grade Concrete Mixed with Two Natural Fibers in Both Curing and Without Curing Condition

Abstract

The mixture of cement, fine aggregate coarse aggregate and water are the constituents of concrete of the building materials which can spread or poured into the moulds and forms a stone like mass on hardening. In this project an attempt is made to add natural fibers in the concrete and compare the compressive strengths of concrete. Coir, jute, can be utilized in concrete and effect of such fibers on properties of concrete can be analyzed. Concrete containing fibers increase the service life and have a positive effect on social life and social economy. Concrete is strong in Compression as aggregate efficiently carries the compression load. Concrete is strong in compression but weak in tension, hence by adding these fibers we can also increase its tensile strength. It has been accepted that addition of small closely spaced and uniformly distributed fibers to concrete would act as a crack arrester and would significantly improve its static and dynamic properties. The study also focuses on the comparative study among fiber added concrete with the structural strength of conventional concrete. In this project, the strength behavior of concrete mixed with natural like coir and jute fibers of fiber cement ratio 0.5%, 1.0%, and 1.5% is compared with the compressive strength of conventional concrete of grade M25 is subjected to curing and without curing condition. The strength behavior of different fibers concrete will be compared.
