What is Recycled Aggregate Concrete?

Jun 29, 2018 Even just a slab of concrete doesn’t make any difference all recycled concrete is aggregated for using subbase material. It can also be paired with new and pure materials. Concrete to be recycled is collected at a demolition yard and placed into a crushing machine. It must be free of any debris such as trash, wood, and paper.
