This document summarizes a study on the strength characteristics of geopolymer concrete. The study investigated how replacing fly ash with varying amounts of glass powder (0-20%) impacted the compressive strength of geopolymer concrete over 7 and 28 days. The maximum 7 and 28-day compressive strengths were achieved with 5% glass powder replacement. The flexural, split tensile, and water absorption properties were also examined. Additionally, the effects of replacing fly ash with ground granulated blast furnace slag (GGBS) at percentages from 5-20% were investigated, with 15% GGBS achieving the highest 28-day compressive strength. The study aims to utilize industrial waste to reduce the environmental impact of concrete production
