2017-06-15· Coarse recycled concrete aggregate (RCA) is a variable material, and that variability can often make it less desirable for usage in concrete infrastructure. One consistent characteristic of RCA however, is a higher absorptive capacity when compared with natural aggregate (NA). Due to this higher absorptivity, there is potential for the RCA to provide some internal curing-like benefits when it ...
