Abstract
The increasing environmental impact of cement production has led to growing interest in using industrial solid waste as a partial cement replacement to reduce CO₂ emissions and landfill accumulation. Nano glass waste, derived from recycled glass, presents a promising alternative due to its fine particle size and pozzolanic properties. This study evaluates the effects of incorporating nano glass waste into mortar on its fresh, mechanical, durability, and thermal characteristics. Mortar mixes were prepared with 0–50% nano glass replacement, and tests were conducted to assess flowability, compressive and flexural strength, acid resistance, and thermal conductivity. The results showed a 39.8% reduction in flowability at 50% replacement. Compressive strength increased by 10.1% at 10% replacement, while flexural strength dropped by up to 25.5% at 50%. Notably, thermal conductivity decreased by 40.31% at 50% replacement, indicating enhanced insulation. These findings suggest that nano glass waste can improve the performance and sustainability of mortar when used at optimal levels based on the intended application. Nano glass waste improves strength at 10% and insulation at 50% replacement in mortar.
