EFFECT OF PARTIAL REPLACEMENT OF CEMENT WITH WASTE GLASS POWDER ON THE PROPERTIES OF CONCRETE

Abstract

3Storage and safe disposal of waste glass is a huge problem for municipalities everywhere. Reuse of waste glass eliminates/reduces this problem. In this experimental work, the effect of partially replacing cement in concrete by glass powder is studied. The cement in concrete is replaced by waste glass powder in steps of 5% from 0% to 40% by volume and its effects on compressive strength, split tensile strength, workability and weight density are determined. It is found that the compressive and split tensile strengths of concrete increase initially as the replacement percentage of cement by glass powder increases, become maximum at about 20% and later decrease. The workability and weight density of concrete reduce monotonically as the replacement percentage of cement by glass powder increases. The replacement of cement up to about 30% by glass powder can be done without sacrificing the compressive strength.
