  • RCA | Recycled Concrete Aggregate | NJ, NY, NYC, PA

    Recycled concrete aggregate, also known as RCA, is an extremely popular replacement for natural stone aggregates. RCA is usually made up of old concrete from sidewalks, pavements, curbing and building slabs. After being compiled the concrete is processed and screened, which includes crushing the concrete into smaller pieces.
