Crushed Returned Concrete as Aggregates for New Concrete

This research project addresses the use of crushed returned concrete, referred to in this report as Crushed Concrete Aggregate (CCA), as a portion of the aggregate component in new concrete. Demolishing old concrete structures, crushing the concrete and using the crushed materials as aggregates is not new and has been researched to some extent.
