Online ServiceThe difference between physical properties of natural aggregate and RCA is influenced strongly by the cement paste surrounding the aggregate in crushed concrete. The absorption of water by RCA is higher than that of natural aggregate and usually the specific gravity is lower Kelly 1998. This affects the use of RCA in concrete road base and
