RESIDUAL LIFETIME PREDICTION METHOD FOR REPAIRED CONCRETE FRAMEWORK, AND METHOD AND PROGRAM FOR CALCULATING NEUTRALIZATION RATE COEFFICIENT USED FOR THE PREDICTION

摘要

PROBLEM TO BE SOLVED: To properly predict the residual lifetime of a repaired concrete framework, from the type of repair materials. SOLUTION: The method calculates the neutralization rate coefficient, included in a neutralization rate equation representing the relationship between the exposure time and the neutralization depth of the concrete framework in the air. When the surface of a neutralized concrete framework is repaired by covering with a mortar-based repair material, the neutralization rate coefficient of the repaired concrete framework is determined from the neutralization rate coefficient of an unrepaired concrete framework and the physical properties of the mortar-based repair material.
