Abstract
Waste glass stockpiling is a significant issue in Australia with approximately 66 kg tonnes of uneconomic and contaminated waste glass fines being produced each year in Victoria alone. The high level of contaminants in waste glass fines could be harmful to concrete while washing glass is not economical and sustainable. Limited research has investigated the effect of contaminants in waste glass fines on the performance of concrete, which has hampered its broader acceptance as a substitution for natural sand aggregate. In this study, the feasibility of utilising unwashed waste glass fines as a sand replacement at 10 wt% was comprehensively investigated, under both laboratory and on-site condit..
