PROBLEM TO BE SOLVED: To provide an anticorrosive composite having both excellent acid resistance and crack resistance, no swelling and peeling, and excellent adhesion. An anticorrosive composite comprising a mortar or concrete surface containing a calcium aluminate-based compound and fine granulated blast furnace slag, coated with a shrinkage reducing agent. The mortar or concrete preferably contains at least one of fly ash, silica fume, pulp sludge incineration ash, sewage sludge incineration ash, waste glass powder, polymer, and fibrous material. Moreover, it is preferable that the usage-amount of a shrinkage reducing agent is 100-500 g / m < 2 >. Furthermore, it is a manufacturing method of the corrosion-proof composite which coats the shrinkage reducing agent on the surface of the concrete containing a calcium aluminate compound and blast furnace granulated slag fine powder.
