Mix Design Of Recycled Aggregate Concrete

Recycled Concrete Aggregates (RCAs) are more porous because of Attached Mortar (AM). AM influences the key properties of RCAs, among which water absorption capacity. AM of RCAs influences the strength of Recycled Aggregate Concretes (RACs). The proposed methodology predicts the RAC strength by considering the key properties of RCAs.
