This study uses varying percentages of glass powder (GP) and ground granulated blast furnace slag (GGBS) as partial replacements for Portland cement to investigate their effects on the behavior of the concrete’s mechanical and durability properties. Due to the adverse environmental impacts of cement manufacturing, there have been efforts to replace cement with supplementary cementitious materials (SCMs) to reduce cement consumption while enhancing concrete performance. This study evaluates the effects of adding varying percentages of silica fume (SF) and ground granulated blast furnace slag (GGBFS) on the mechanical and durability properties of the modified concrete. It also evaluates their compressive, tensile, and flexural strength and conducts the Initial Surface Absorption Test (ISAT), carbonation test, and microstructure analysis using scanning electron microscopy (SEM). The research variables are partial cement replacement with varying percentages of 5%, 10%, 15%, and 20% of different pozzolanic materials. The water-cement ratio in this experiment is 0.53.
