Recycled concrete aggregate, also known as RCA, is an extremely popular replacement for natural stone aggregates. RCA is made up of old concrete from sidewalks, pavements, curbing and building slabs by processing the material through a crusher. In comparison to other fills, RCA is more economical and performs equally as well.
