Sustainable utilisation of low-grade and contaminated waste glass fines as a partial sand replacement in structural concrete

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 economi...
