Crushed Stone The Unsung Mineral Hero

Used portland cement concrete from demolition sites is often taken to a quarry or to a distribution yard, where it is crushed, processed to remove metal, screened to size, and then sold as a crushed stone substitute. This material works well as fill, road base, and in other uses where the stone does not have to meet strict specifications.
