The purpose of this research is to investigate the feasibility of using bullet plastic as coarse aggregate or as a substitute for air bubbles in the production of lightweight concrete. The mechanical properties of plastic bullet-aggregated concrete substituted with 25%, 50%, 75%, and 100% of the gravel volume were evaluated experimentally. The mechanical properties tested were compressive strength, split tensile strength, and flexural strength. The test results show the mixture of 75% and 100% plastic bullets yields an acceptable density value as a lightweight concrete, with compressive strengths of 15.56 MPa and 14.94 MPa. These findings suggest that using plastic bullets as coarse aggregate or as a replacement for air bubbles is feasible regarded to American Concree Institute (ACI).
