Influence of admixtures on mechanical properties of fibre reinforced concrete

Abstract

In this paper presents the mechanical properties of the fiber reinforced concrete. For that the experimental work should be done by using natural fiber that is coir ond it should be done on by using M5O grade of concrete. In this project we are going to use the admixtures also at different percentages by the replacement of the cement material. By adding the admixtures the characteristic strength of the concrete also improved when compared to the normal concrete. The mechanical properties like the compression strength, flexural strength, density and ductility of theconcrete be calculated .in this experimental work the coir fiber was added up to the 0.4% of the binder volume of the concrete mixture. In this work the admixtures like flyash and silica fumealso mixed at 10% and 20% respectively. By using this experimental work,ductility,modulus of elasticity and ultra pulse value ofreinforced concrete also determined.
