About this site

Mar 01, 2007  Construction and demolition (CD) waste could be broken concrete, bricks from buildings, or broken pavement. Thus, Recycled Aggregate (RA) could come from the demolition of buildings, bridge supports, airport runways, and concrete roadbeds. Concrete made using such aggregates is referred to as recycled aggregate concrete (RAC).
