SUSTAINABLE CONCRETE PRODUCTION USING WASTE GLASS POWDER AS A PARTIAL REPLACEMENT OF FINE AGGREGATE

Abstract

The construction industry, in response to environmental concerns tied to traditional methods, explores alternative materials for concrete. The study aims to investigate the strength of concrete using waste glass powder as a partial substitute for sand. Waste glass powder was varied in concrete by 10%, 20%, and 30% replacement with sand. Silt and sieve analysis tests and compressive and water absorption tests were conducted on the constituents of concrete. Findings show that the water absorption test performed on the sample of 30% replacement of sand with waste glass powder absorbed 5 times less water. Percentage replacement of 20% and 30% have compressive strengths greater than the control samples.
