As compared to natural aggregates (NA), reused concrete aggregates (RCAs) made from demolition and construction waste often have higher absorption capacities. In case of M30, RCA with the substitution up to 30% of NA along with cement content of 438 kg/m 3 is appropriate for structural construction.
