Abstract- In the present study, an experimental investigation has been carried out to evaluate the mechanical and durability properties of geopolymer concrete incorporating glass powder as a partial replacement of Ground Granulated Blast Furnace Slag (GGBS). The primary objective is to utilize waste glass as a sustainable construction material and reduce dependency on conventional cementitious materials. Five different mixes were prepared with glass powder replacement levels of 0%, 10%, 15%, 20%, and 25%. The mix proportions were designed by keeping coarse aggregate, fine aggregate, and sodium silicate constant, while GGBS was partially replaced with glass powder. The properties studied include compressive strength, flexural strength, and water absorption. The results indicated that up to 15% replacement of GGBS with glass powder improves strength due to pozzolanic reaction, while higher replacement reduces strength. The study concludes that glass powder can be effectively used in geopolymer concrete for sustainable construction.
