Abstract

This research investigates the environmental and economic benefits of using recycled concrete aggregates (RCA) in the production of paver blocks, cover blocks, and kerb stones. A Life Cycle Cost Analysis (LCCA) was conducted, revealing a 20-30% reduction in material procurement costs when using RCA compared to traditional aggregates. The study also highlights substantial savings in transportation and disposal costs, with RCA reducing transportation costs by 30% and disposal costs by 50%. Environmental assessments showed a reduction in carbon emissions by 20-25% when RCA was used, along with a significant decrease in resource depletion and landfill waste. Mechanical testing of RCA products demonstrated that paver blocks, cover blocks, and kerb stones with up to 60% RCA maintained acceptable performance, with compressive strength ranging from 30 to 35 N/mm2, suitable for medium traffic applications. This study provides strong evidence that RCA is a cost-effective and environmentally sustainable alternative to conventional construction materials.
