The primary goal of the current paper is to evaluate the viability of the sustainable concrete (S.C) made of waste glass sand (WGS) and waste plastic sand (WPS). This paper looks at concrete mixtures as follow: the first group (5%, 10%, and 15%) WGS as the sand replacement and Group Two (5%, 10%, and 15%) WPS as a natural sand replacement, and finally, group three HRS where, (5%, 10%, and 15%) of WSP/WGS were evaluated as sand substitutes. Tests were done on the concrete to ensure that the tested concrete's behavior was within expectations. Among these tests are the slump test, compressive strength test, indirect tensile strength test, flexural strength, and elastic modulus test. The results showed that using WGS and WPS together improved the slump of the concrete mixtures. Adding WPS or HRS to concrete mixes enhanced the mechanical properties, and Compressive strength increased, reaching a maximum of 52.05 MPa after partially substituting natural sand with WGS-10% of sand. And finally, when replacement ratios were high, the results showed that the concrete's compressive strength decreased when WGS-15% and WPS-15 % were substituted at 9.85% and 14.45% respectively.
