The Crushed rock fine have been used as fine aggregate in concrete for centuries. But Crushed rock fine has the major problems of being angular in shape and containing excessive fines. To resolve these problems, the technology of processing Crushed rock fine to improve the particle shape and reduce the fines content has been developed. Such processed Crushed rock fine is called manufactured sand.
