A Study On The Compressive Strength Of Concrete Using Waste Glass As Partial Replacement Of Fine Aggregate

Abstract

Waste management is becoming one of the major concerns of the 21st century. As a nonbiodegradable solid waste, glass cannot be considered for landfill. So, recycling opportunities must be explored. On the other hand, the concrete industry is using finite natural resources and also harming the environment. Therefore, making concrete production more sustainable and recycling solid waste, using waste glass as a partial replacement for fine aggregates holds considerable appeal. This study sought to ascertain the degree of glass substitution that would yield the highest achievable compressive strength. Three concrete samples were tested at 14 days and 28 days, wherein the ratios of glass replacement were measured at 15, 20, and 25%. Compressive strength was increased by up to 20%, at which point the strength developed was 1.5% and 2.5% higher than the control after 14 and 28 days respectively. The findings indicate that the incorporation of fine glass aggregate in concrete up to a proportion of 20% leads to an increased development of compressive strength as compared to conventional concrete.
