The RMC Research & Education Foundation released a study on Crushed Returned Concrete as Aggregates for New Concrete.
Performed at the National Ready Mixed Concrete Association’s Research Laboratory, the report evaluates the effects of the use of crushed-concrete aggregate on fresh and hardened concrete properties by comparing these properties to concretes containing virgin aggregates. The report includes guidance for ready-mixed concrete producers on a methodology for the appropriate use of crushed-concrete aggregates in concrete.
