摘要

The rapid increase in electronic waste plastics poses serious health and environmental risks, with 80%–85% ending up in landfills and releasing toxic emissions. Recycling e-waste plastic in concrete offers a sustainable and effective solution to reduce pollution and manage waste responsibly. In this research, natural fine aggregate was partially substituted with 0−20% electronic waste plastic by weight to produce an M55 grade of concrete, and fundamental examinations like slump, split tensile strength, compressive strength, and dry density were performed. Test results revealed that workability decreased by 4.16−16.67%, compressive strength by 5.30−16.93%, split tensile strength by 20.07%–29.82%, and dry density by 0.65−3.50% with 10−20% replacement of fine aggregate with respect to the control concrete. Although mechanical properties slightly declined with increased e-waste plastic content, the concrete’s reduced density indicates slightly low-density concrete as compared to a normal mix, suitable for lowering structural self-weight. This method not only helps manage e-waste and conserve natural resources but also reduces environmental impact by diverting waste from landfills. The findings demonstrate that partial replacement of conventional aggregates with electronic plastic waste offers a sustainable solution for construction with minimal compromise on strength.
