Mechanical Properties of Concrete Combinations Containing Waste Glass Powder

Abstract

In this study, waste glasses that can not be recycled were used in concrete as a pozzolan and fine aggregate. They were ground and incorporated into concrete with the levels of 5%, 10% and 15% by the weight of binder. To evaluate these replacements, a number of laboratory tests were carried out. These tests included workability, unit weight, compressive strength, flexural strength and the alkali-silica reaction (ASR). The experimental results indicate that the mixtures which were ground with 5% waste glass as a pozzolan and 10% waste glass as fine aggregate gave compressive strength performance similar to the reference mixture. Higher percentage of waste glass (15%) replacement yielded lower strength values. This study shows that using waste glass materials in concrete to reduce the cost and helps us to solve some part of the solid waste problems.
