Experiment on Foam Concrete with Quarry Dust as Partial Replacement for Filler

Abstract

Foam concrete is a type of lightweight concrete. It is non-load bearing structural element which has lower strength than conventional concrete. Foam concrete has been successfully used and it has gained popularity due to its lower density than conventional concrete. It is created by uniform distribution of air bubbles throughout the mass of concrete. Recently, most studies on foam concrete concern on the influence of filler type used in manufacturing foam concrete. The density of foamed concrete is a function of the volume of foam added to the slurry and the strength decreases with decreasing density. This study was conducted to determine the compressive strength of foam concrete by using quarry as partial sand replacement material. This report presents the feasibility of the usage of quarry dust as 10 %, 20 % and 30 % and 40% substitutes for sand in foam concrete. Mix design were developed for various densities of foam concrete and their replacements. Tests were conducted on cubes study the strength of concrete made of quarry dust and results were compared with the control foam concrete. It is found that the compressive strength of foam concrete made of quarry dust are nearly 40 % more than the control foam concrete.
