Experimental Investigation on Strength Characteristics of Concrete containing Fly Ash and Micro silica

Abstract

From the investigation this paper express that the strength and durability characteristics of M40 grade concrete in which cement is partially replaced by rice husk ash and coir. Coconut fibers are reported as most ductile and energy absorbent material. It is concluded that coconut fibers have the potential to be used in composites for different purposes. Rice husk ash is obtained by burning rice husk in a controlled manner without causing environmental pollution. There is a good potential to make use of RHA as a valuable pozzolanic material to give almost the same properties as that of micro silica. In this study, the strength related properties such as compressive strength, splitting tensile strength, flexural strength were calculated and better durability characteristics when compared to other replacement levels.
