Effect of Recycled Coarse Aggregate on Concrete

Coarse recycled concrete aggregate (RCA) is produced by crushing the demolition waste of at least 95% by weight of concrete, and having a total contaminant level typically lower than 1% of the bulk mass. Other materials that may be present in RCA are gravel, crushed stone, hydraulic-cement concrete or a combination thereof deemed suitable for premix concrete production (Anonymous,
