Özet

The use of coarse recycled concrete aggregates on concrete applications can substantially reduce the environmental effects and the exhaustion of the natural resources. The researchers suggest that coarse recycled aggregates should be processed appropriately and used in applications with low strength concrete. This study was carried out to investigate the possibilities of using the coarse aggregate from concrete waste as coarse recycled aggregate in concrete. In the study, coarse recycled concrete aggregate (FRCA) was used in the ratio of 0, 10, 20, 30, 40, 50 and 100 % respectively in place of crushed sand. Compressive stress, unit weight and water absorption rates tests were determined for these concrete samples for 28 days. According to the test results, it was found that recycled aggregate could be used in place of fine aggregate up to 30%.
