Compressive Strength Improvement of M30 Grade Concrete As a Partially Replacement of Coarse Aggregate With E- Waste Plastic

This project studies the compressive strength of M30 grade concrete by partially replacing coarse aggregate with E-waste plastic at 15%, 25%, and 35%. The main aim is to reduce environmental pollution caused by electronic waste and to check whether E-waste plastic can be used in concrete without reducing its strength. Concrete cubes are cast and tested for compressive strength after 7 and 28 days of curing. The results are compared with normal concrete to find the optimum replacement percentage. This study promotes sustainable construction and proper use of E-waste materials.
