The 411 on Recycled Concrete: Uses, Benefits, and How

Old, unneeded concrete can be recycled and used to create recycled aggregate. In most cases, recycled aggregate will be used as a subbase material, but it can also be paired with virgin materials and reused as an aggregate in new concrete. CA6 recycled PCC and Grade 8 recycled are common aggregates made from recycled concrete.

WhyHow to Use Recycled Crushed Concrete Superior

Nov 07, 2019Rip-rap, sometimes referred to as riprap, shot rock, rock armor, or rubble, is larger slabs of recycled concrete used along shorelines to control erosion or form a breakwater. Smaller gravel bits of RCA are often used as a sustainable, affordable subbase for roads. Dry aggregate can even be reconstituted as new concrete.
