Abstract—The utilization of glass powder (GP) in concrete production contributes to a more sustainable and environmentally friendly construction practice. In commercial establishments, damaged glass sheets and glass cuttings are often discarded as waste and sent to landfills, as recycling of such materials is not commonly practiced. Incorporating glass powder in concrete offers a promising approach for reducing waste disposal and promoting environmental conservation.

This study investigates the feasibility of using glass powder as a partial replacement for fine aggregates in concrete. Natural sand was substituted with glass powder at varying proportions of 10%, 20%, and 25%. The compressive strength of concrete cubes was evaluated at curing ages of 3, 7, and 28 days, and the results were compared with those of conventional concrete made with natural sand.

Keywords— Glass powder, Natural sand, Compressive strength.
