Recent years have witnessed an increase in the quantity of waste glass (WG) across the globe. Replacing the fine aggregate with WG is one of the steps toward preserving the natural resources of the environment and creating low-cost concrete. The present study is concerned with replacing fine aggregates with glass powder (GP) at (0%, 15%, 30%, and 50%). It has studied the fresh and hardened properties (compressive strength, tensile strength, hardened density, and slump) for all the mentioned percent replacements. The findings have shown that all mixtures containing GP gave acceptable slump results within the design limits (2-5 cm) according to ACI standard 211.1. It has been observed that increasing the proportion of GP led to a decrease in the weight of concrete. Lastly, replacing GP with sand by 30% has led to an increase in the compressive strength by about 2.4% and 12.45%, and the tensile strength by about 2.5% and 26.54% at 7- and 28-d, respectively in comparison to normal concrete.
