摘要： PROBLEM TO BE SOLVED: To provide a repair method for a mortar or concrete construction which method allows determining the life period of the mortar or concrete construction to be a desired period to enable efficient repair of the mortar or concrete construction. SOLUTION: A corrosion deterioration depth (a) per given period of an existing mortar or concrete construction is determined. An acidproofness ratio (b) between the motor or concrete used for the existing construction and repair mortar or concrete is also determined. Based on the corrosion deterioration depth (a) and the acidproofness ratio (b), a repair thickness (d) of mortar or concrete that meets a desired life period (c) is calculated according to the following equation (3). A corroded/deteriorated portion of the mortar or concrete of the existing construction is eliminated, and the eliminated portion is filled with the repair mortar or concrete so that its thickness reaches the repair thickness (d). The equation (3) is given as d=a×b×c+e, where e represents a thickness set in consideration of safety. COPYRIGHT: (C)2008,JPO&INPIT
