Recycled Aggregate - an overview | ScienceDirect Topics

The EMV method has been applied for RCA only, and it considers the recycled aggregate as a two-phase material, consisting of the natural aggregate and the mortar attached to it, which must be quantified and included in the proportions of the mix, as a source of cement and sand. This allows the recycled concrete mix to be designed with a similar internal structure to that of the natural concrete used as a reference.
