Abstract

The use of plastic waste as a substitute for aggregates is the solution to environmental problems. Plastic waste can improve concrete performance such as resistance to abrasion, impact loads, ductility, shock absorption, and thermal conductivity. However, the addition of plastic waste will reduce the mechanical properties of concrete. This weakness can be overcome by adding steel fibers in the form of Dramix 3D 80/60. Increased levels of PET plastic cause concrete workability to decrease, so a superplasticizer is added to improve the workability of concrete. The purpose of this study is to analyze the mechanical behavior of concrete using PET plastic waste as a partial aggregate replacement. The method used is an experimental study with variations in PET plastic content of 0%, 10%, 15%, and 20% of the volume of coarse aggregate. Mechanical testing in concrete is obtained that the greater the addition of PET plastic content, the greater the decrease in compressive strength, flexural strength, tensile strength, and modulus of elasticity of concrete
