Abstract: Many research works went to investigate about concrete properties contains metal and plastic trash, to improve some mechanical properties of concrete in tension and flexural in addition, to use this trash as an admixture to improve its properties, its work to clearance the environment from harmful waste. The main goal of this research is to investigate some important mechanical properties like compressive strength, splitting tensile strength, flexural strength and load-deflection test. Reference concrete used by mix proportion 1:1.5: 3 and water to cement ratio 0.45. The results of tests show that increase in compressive strength, splitting tensile strength, flexural strength of concrete contains plastic trash due to reference concrete (14, 48, 19%), (9, 20, 6%) for ages 28 and 56, respectively and increase in compressive strength, splitting tensile strength, flexural strength of concrete contain metal trash due to reference concrete (13.3, 60, 31%), (12.3, 0.0, 8.6%) for ages 28 and 56, respectively. The results of tests show that increase in capability of loading of samples due to deflection (23, 35%) between concrete contains plastic, metal trash and reference concrete.
