Strengths for Recycling as Coarse Aggregate

Jul 26, 2021  The coarse aggregates presented in demolished concretes, when correctly liberated by comminution and separated from the remaining material (basically cement paste and sand), may be used as coarse aggregate [11,22] to replace natural aggregates. Some studies of old concrete comminution and recycling are presented in the litera-ture.
