This document discusses a research study on using waste glass powder as a partial replacement for cement in concrete. The objectives were to increase workability, compressive strength, and lighten the concrete, while also reducing landfill waste. Glass powder replaced up to 30% of cement in the concrete mixes. The results showed that mixes with glass powder had higher workability and only slightly lower compressive strength compared to standard mixes. The glass powder also lightened the concrete. Therefore, the study concluded that using waste glass powder in concrete is an effective way to increase sustainability while maintaining adequate performance properties.
