1) An experimental study was conducted to determine the effectiveness of using recycled coarse aggregates (RCA) in concrete. Concrete mixes were prepared by replacing normal coarse aggregates with RCA at percentages ranging from 20-40%.
2) Compressive strength tests were performed on concrete cubes at ages of 12 hours, 3 days, 7 days, and 28 days. The results showed that concrete with 40% replacement of RCA achieved higher compressive strengths compared to normal concrete at 28 days.
3) Replacement levels of 20-25% RCA resulted in compressive strengths similar to normal concrete at all ages tested. Higher replacement levels of 30% showed similar early strengths but decreased 28 day strength. The study concluded
