CORROSIONPROOFING METHOD OF CONCRETE BUILDING OR CONCRETE PRODUCT AND RESULTANT CORROSIONPROOF CONCRETE PRODUCT

摘要

PROBLEM TO BE SOLVED: To prevent a concrete from corrosion so as to satisfy both sufficient coorosionproofness and durability thereof. SOLUTION: A concrete building 1 or concrete product 2 is subjected to corrosionproofing treatment by making the surface to be treated 4 of the concrete building 1 or concrete product 2 mechanically or physically rough-surfaced followed by spraying a single or composite corrosionproof material 6 to the resultant surface 4 to form either one corrosionproof layer 8 or a plurality of corrosionproof layers 8 with a variety of the spraying materials 6 on the surface 4.
