Abstract

Abstract: This study investigates the potential of using plastic waste as a partial replacement for aggregates in concrete production, aiming to address the dual challenges of unsustainable construction practices and the global accumulation of plastic waste. With an emphasis on sustainability and waste management, the research explores the effects of incorporating different percentages of plastic waste (0%, 5%, 10%, 15%, and 20%) on the mechanical properties, durability, workability, and thermal behavior of concrete. The methodology encompasses the collection and preparation of plastic waste, formulation of concrete mixes with varying levels of plastic waste replacement, and comprehensive testing of the prepared specimens for compressive strength, flexural strength, split tensile strength, workability (slump test), durability (freeze-thaw cycles), impact resistance, and thermal conductivity. The analysis of results reveals that while the inclusion of plastic waste in concrete leads to a reduction in mechanical strengths, it simultaneously improves workability, durability against freeze-thaw cycles, impact resistance, and thermal insulation properties
