Recycling of Concrete (Recycling Coarse Aggregate)
Recycling of concrete is a simple process. It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality. As per study about 75 to 80% of total construction material consist coarse aggregate portion. When the structure is demolished, the waste concrete in a large quantity is produced.

A REVIEW OF RECYCLED CONCRETE AGGREGATES AS …
recycled concrete aggregates (RCA) [4]. Initially, the recycled aggregate (RA) was used for non-structural purposes such as fill material, base course material and foundations, however, modern research has shown that it is viable option to use recycled concrete aggregates to replace natural aggregates (NA) in structural concrete.
