Study On Partial Replacement of Powdered Waste Plastic with Fine Aggregates in Concrete

Abstract

Using powdered waste plastic as a partial replacement for fine aggregates in concrete is a concept that has gained attention in recent years as a sustainable and environmentally friendly approach to waste management. Incorporating waste plastic into concrete can have several potential benefits, but it also comes with certain challenges. The objective is to develop a suitable composition for a concrete mixture by replacing fine particles with pulverised and granular plastic. To attain the desired strength, the design incorporates a combination of pulverised and granular plastic in concrete, taking into account specific properties such as density, workability, flexural strength, compressive strength, and tensile strength. The restricted movement of aggregates caused by the plastic's resistance could explain the impact of the plastic on the concrete's workability. Moreover, the dried density is reduced, resulting in the formation of a lightweight concrete. The inclusion of waste plastic material in concrete results in a reduction of compressive strength compared to traditional concrete.
