A Review Paper on Strength and Durability Study of Concrete by Using Rice Husk Ash and Coconut Fiber

Abstract

This project based on use of Rice Husk Ash as a replacement of cement content. rice husk ash a waste material. This waste material rice husk ash contain SiO 2 use for their characteristic like optimum strength, good durability etc. rice husk ash is an agro waste and known to be a super pozzolona have been used for mass concrete. Due to quick urbanization there is a rapid development of tall building and long span concrete structures. Fibers increase the flexural toughness and increase shatter and abrasion resistance, improving concrete long term durability and integrity. The new composite made by coconut fiber and rice husk ash possess superior properties in terms of strength, cohesion, low permeability and enhanced chemical resistance and at the same time reduce shrinkage cracking too. The topic entitled "strength and durability study of concrete by using Rice Husk Ash and Coconut Fiber" comprise the development of concrete using different range of RHA and coconut fiber. The present study is carried out for evaluating the influence of Rice-husk ash and Coconut fibers in M30, M40 and M50 grade concrete. This study presents the results of workability, compression test, durability test and split tensile test on concrete which were casted with various percentage of Coconut fibers ranging from 0% to 4% at a regular interval of 1% and Rice-husk ash ranging from 0% to 30% at regular interval of 10%. Total 27 mix will designs considered and average result of 3 cubes and 3 cylinders was taken as compressive strength and tensile strength of that mix design.
