Selected Mechanical and Physical Properties Concrete with Polypropylene Plastic Granule Aggregate

Abstract

Abstract Amount of plastic use contribute significantly to the accumulation of plastic waste. The use of plastic waste in concrete is one of the world’s partial solutions for dealing with plastic waste. Polypropylene plastic granules are used as a partial replacement for fine aggregate in this study. The purpose of this research is to examine the physical and mechanical properties of the chosen base concrete while considering the potential of polypropylene plastic granules as a sand substitute in the concrete mixture. Variables to be investigated incorporate compressive strength, split tensile strength, workability, and density. The results of this study show that using polypropylene plastic granules as a substitute for fine aggregate at 10%, 20%, 30%, and 40% rates slump values of 8.1 cm, 8.4 cm, 8.6 cm, and 8.8 cm, respectively. However, it does not perform well in terms of compressive strength or split tensile strength. The strength reduction achieved by using 40% PP plastic granule can reach 58.06 percent.
