• What is Crushed Aggregate (with pictures)

    Aug 14, 2019 路 Crushed aggregate, also known as rock aggregate, refers to a crushed stone product produced in quarries. In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger stones are processed in an impact crusher to create crushed rock aggregate. The greater costs of production involved in mining and processing the stones to create crushed aggregate.

    Feb 03, 2012 路 ACI allows both crushed rock and rounded aggregate, but goes over some of there differences in the guide. A couple highlights 1) Both generally have same compressive strength for same cement content. 2) crushed typically requires higher water requirement than rounded. 3) Rounded aggregate may increase the pumpability of the concrete.
