Durability of crushed fine recycled aggregate concrete
After decades of studies, the partial use of coarse recycled aggregates is considered acceptable, yet the use of fine recycled aggregates (FRAs) is highly restricted in concrete production. This restriction is based on technical concerns; for example, the presence of FRAs in concrete allegedly hinders its performance beyond acceptance.
