What is Crushed Aggregate? (with pictures)

May 16, 2020 Crushed aggregate is produced in quarries by processing larger rocks into smaller pieces. All aggregate is divided into two types: fine and coarse. Fine aggregate is broken up into smaller pieces than coarse aggregate. When put through a separator or aggregate washer, coarse crushed aggregate

What Is Crushed And Uncrushed Aggregate

Crushed And Uncrushed Aggregates. Crushed And Uncrushed Aggregates Chollet. Coarse aggregates consist of crushed or uncrushed gravel or crushed stone minus the fine aggregates which consist of natural sand, manufactured sand, or a combination of the two according to sustainableconcreteorg, coarse aggregates can either be from " primary, secondary or recycled sources.
