摘要

PROBLEM TO BE SOLVED: To provide a method for preventing corrosion of steel in a mortar or a concrete member for a long term, which can easily change a corrosion prevention material for the steel, and to provide the corrosion prevention material for the steel used in the method.;SOLUTION: The method for preventing corrosion of the steel in the mortar member or the concrete member, comprises filling the corrosion prevention material for the steel containing a metal having higher ionization tendency than the steel material of the member, and a coating material which retains a solution of high pH, in an opening of a frame such as concrete, and connecting the steel material with the metal, especially the steel in a corrosive part. The method for preventing corrosion of the steel comprises arranging the opening in a peripheral part around the exposed part of the steel in the frame, and filling a recovering material in the exposed part of the steel to recover the part. The corrosion prevention material for the steel is used in the methods.;COPYRIGHT: (C)2003,JPO
