Durability of concrete by partial replacement of coarse aggregate with recycled plastic granules

Abstract

This research investigates and reports on the usage of plastic granules in place of coarse aggregate while constructing concrete cubes and cylinders. Concrete cubes and cylinders made of plastic granules were hand cast, and the concrete's strength was then empirically assessed in terms of split tension and compression. It has been discovered that the compression and split tension strengths of plastic-replaced concrete can be on par with those of ordinary concrete. The current analysis focuses on concrete mixes that have plastic granules (0%, 5%, 10%, 15%, 20%, and 25%) partially replacing the coarse aggregate, which will help reduce the structure's dead weight. This mix, in the form of cubes and cylinders, was subjected to compression and split tension to ascertain the strength parameter. Therefore, using plastic granules for creating concrete is not only advantageous but also useful for getting rid of plastic trash.
