Experimental Investigations on Lightweight Aggregate Concrete using Rice Husk Ash

Abstract

In this study, the ideal amount of replacement for rice husk ash (RHA) is produced by burning rice husk at a temperature of 500 °C, as a blending component in cement, has been determined. The initial step was to analyze RHA's physical and chemical characteristics. The study looked at using artificial cinder particles to develop a lightweight aggregate concrete. The study's objective is to produce sustainable lightweight aggregate concrete and evaluate its mechanical and durability properties. The compressive strength, tensile strength, and flexural strength increased when cement was replaced by 20% RHA. The water permeability decreased when cement was replaced by 20% RHA due to the reduction in air content.
