An Overview of Recycled Concrete Aggregate - ETM

Sep 27, 2020  Recycled aggregates are only classified as recycled concrete aggregates (RCA) when the primary material is concrete. By crushing and compressing existing waste concrete and combining it with aggregate, producers can create concrete aggregate to a specific size and quality, which makes it very cost effective to purchase.
