The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.

This paper concluded that RCA concrete made with RCA from high strength source concrete with low water absorption perform like conventional concrete, while low strength source RCA with high water absorption yields a modulus of rupture less than predicted, likely due to the weak residual mortar layer (Yang et al. 2008).

Natural aggregates are formed by process of weathering and abrasion or by artificially crushing large parent mass. Because cement is the most expensive ingredient in making concrete, it is desirable to minimize the amount of cement used. 70 to 80% of the volume of concrete is aggregate in order to keep the cost of the concrete low.
