Abstract: The use of waste aggregate in concrete is very important because of that decrease the total cost of concrete and lead to a more clean environment. This research aims to study the mechanical properties such as compressive, tensile and flexural strength and also the modulus of elasticity for concrete containing waste glass as coarse and fine aggregate and improved also with integral waterproofing admixture. The study shows the improvement in mechanical properties due to using waste glass only and waste glass with integral waterproofing admixture, compressive strength increased from 27.3-35.8 MPa by total glass replacement but using both glass and waterproof lead to rise compressive strength to 54.38 MPa also other mechanical properties increased highly by using glass and waterproofing admixture .
