<p><P>PROBLEM TO BE SOLVED: To provide an anticorrosive composite body having excellent acid resistance and cracking resistance, and being free from swelling and peeling and excellent in bonding properties. <P>SOLUTION: The anticorrosive composite body is coated on its surface of mortar or concrete containing calcium aluminate compounds and fine powder of granulated blast furnace slag with a shrinkage reducing agent. Preferably, the mortar or concrete contains at least one kind selected from fly ash, silica fume, pulp sludge incineration ash, sewage sludge incineration ash and waste glass powder, a polymer, and a fibrous substance. The amount of the shrinkage reducing agent to be used is preferably 100-500 g/m<SP>2</SP>. The method for manufacturing the anticorrosive composite body by coating the surface of concrete containing calcium aluminate compounds and fine powder of granulated blast furnace slag with the shrinkage reducing agent is also provided. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
