Seeking new sources of renewable construction materials to address the scarcity of sustainable development is still a challenging matter for scholars in all sectors. One of the best solutions to these challenges is using treated desert sand (TDS) as fine aggregate in concrete production. This study aims to enhance concrete's strength and water absorption using different TDS content. To achieve this aim, five concrete mixtures have been prepared with TDS content of 0, 25, 50, 75, and 100% and show their effect on concrete's density, compressive strength, and water absorption. The study's results explored that using 50% TDS instead of natural aggregate recorded the highest compressive strength of 55.45 MPa at 180 days. While the use of 25% TDS recorded the lowest water absorption of concrete, it is only 3.59%. The results obtained from this study indicate that the addition of TDS has a main effect on the strength and durable concrete especially with 25% and 50% replacement levels. This study recommends to use of large amounts of TDS to address the concrete issues and reduce the cost and environmental issues.
