A SUSTAINABLE APPROACH TO CONCRETE PRODUCTION USING RECYCLED PAVEMENT MATERIALS

Abstract

The growing deterioration of the environment, fueled by rapid urbanization and excessive resource consumption, has highlighted the urgent need for sustainable construction practices. One promising approach is the incorporation of recycled pavement waste aggregate as a partial replacement for natural aggregate in concrete production. This study investigates the environmental and structural viability of using recycled aggregate in concrete by replacing 5%, 10%, 15%, and 20% of conventional aggregate. The workability of fresh concrete was evaluated through slump cone and compaction factor tests, while compressive strength tests were conducted to assess the performance of hardened concrete. Experimental results reveal that concrete containing recycled aggregate demonstrated satisfactory performance compared to conventional concrete. The findings suggest that partial replacement of natural aggregate with recycled material can reduce construction costs, conserve natural resources, minimize energy usage, and offer an environmentally responsible alternative without significantly compromising strength and durability.
