This research examines the impact of Recycled Concrete Aggregate (RCA) and Waste Glass Powder (WGP) on the durability properties of concrete. To encourage sustainable construction practices and mitigate the environmental impact of conventional concrete production, WGP was employed as a partial replacement for natural fine aggregate, while RCA was substituted for natural coarse aggregate in varying proportions of 0%, 10%, 20%, 30%, 40%, and 50%. The durability of the developed concrete mixes was evaluated using the Water Absorption Test, Water Permeability Test, and Rapid Chloride Penetration Test, which were performed at curing ages of 7, 14, and 28 days. The results show that the concrete mix with a 20% replacement of both WGP and RCA performed the best in terms of decreased water absorption, permeability, and resistance to chloride ion penetration. According to these results, the optimum substitution level for incorporating sustainable materials and improving durability is 20%. This indicates the effectiveness of using WGP and RCA in concrete without impacting their durability.
