The use of plastic has been increasing in various aspects of modern life, leading to a huge amount of plastic waste, which affects negatively the environment and humanity. In this paper, the effect of high density polyethylene (HDPE) and low density polyethylene (LDPE) wastes as a partial replacement of natural sand is studied and examined some mechanical properties of concrete. All specimens (60 specimens) were tested after 7 and 28 days. Concrete mixes containing minced polyethylene were prepared by using the replacement ratios partially (5, 10, 15, and 20) by volume of sand. The test results showed that the density of HDPE and LDPE decreased with the increased amount of polyethylene ratios. The values of compressive and splitting tensile strengths for the specimens containing HDPE were higher than the strengths of specimens containing LPED. The results also showed the specimens with 5% and 20% replacement ratios an increase in the strengths, while the specimens with 10% and 15% replacement ratios showed varying behavior of the strengths.
