CORROSION PREVENTIVE METHOD FOR REINFORCED CONCRETE STRUCTURE

摘要

PURPOSE:To provide the method which is easily applicable even to a reinforced concrete structure having intrinsic shapes and inexpensively imparts the corrosion preventiveness excellent over a long period nearly on a par with the corrosion preventiveness of the conventional system of an external power source system with good workability to the structure. CONSTITUTION:A primer layer 3 having a rough surface is formed on the surface of the reinforced concrete structure 1 and a thermally sprayed film layer 4 is formed by thermal spraying of aluminum, etc., on the primer layer 3. A DC voltage is impressed to the thermally sprayed film 4 as anode and the reinforcing steel bar 2 in the concrete structure 1 as cathode to pass the corrosion preventive current between both.
