coarse aggregate recycling process In this study, the recycled aggregate has been used from a crushed concrete cube. The researcher manually crushed the concrete to match the specifications of the gradation of the coarse aggregate. After the washing process to get rid of dust and drying, the researcher tested the recycled aggregate such as coarse aggregate.
