This paper deals with the effects of sorts and contents of impurities in recycled coarse aggregate on the properties of recycled concrete. Recycled aggregate which was assumed producing from reinforced concrete structure of wall, floor and roof slub with several sorts of finishing materials. The sorts of finishing materials for original concrete were a multi-layer wall coating (ML), a synthetic resin emulsion paint (EP), a gypsum plaster (GP), a lime plaster (LP), a fibrous wall coating (FW), a ceramic tile (CT), a plastic tile (PT) and an asphalt membren water proofing (AM). The items of the investigations were on the compressive strength, static modulus of elastisity and drying shringkage of the recycled coarse aggregate concrete.
