Recycled Concrete Aggregate an overview | ScienceDirect

Recycled concrete aggregates (RCAs) are expected to result in an increase in the water absorption of concrete, The RCAs, coded new recycled concrete aggregates (NRCAs), were obtained from crushing a batch of new concrete produced by a ready-mixed concrete supplier after 6 months of outdoor curing. The crushed NRCAs were further sieved into three size fractions: 10–20, 5–10, 2.36–5
