The natural concrete aggregate (NCA) was replaced with RCA at the levels of 0, 25, 50, 75, and by weight. Experimental results showed that the RCA had higher water absorption and lower dry-rodded density than those of NCA. However, the water absorption of RCA can be improved by using various surface treatments.
