The size of the aggregate bigger than 475 mm is considered as the coarse aggregate ie basically all other aggregates which are retained on 475mm IS sieve while sieve analysis is performed According to sources of coarse aggregates it can be further classified as a Uncrushed Gravel or Stone It results from natural disintegration of rock...
