Parent Concrete Strength Effects on the Quality of Recycled Aggregate Concrete: A Review.

Previous studies in the literature have illustrated that the strength properties of the parent concrete (PC), that might come from an assortment of origins, may considerably affect the characteristics of Recycled Concrete Aggregates (RCAs) and Recycled Aggregate Concrete (RAC). The effects of PC strength on physical, mechanical, long-term, and microstructural properties of RCAs and RACs have been extensively studied. These properties include water absorption, specific gravity, compressive strength, elastic modulus, splitting tensile strength, flexural strength, durability, and microstructure.
