CORROSIVE ENVIRONMENT MEASUREMENT METHOD AND CORROSIVE ENVIRONMENT MEASUREMENT SYSTEM FOR STRUCTURE, AND REPAIR PLAN FORMULATION METHOD AND INSPECTION PLAN FORMULATION METHOD USING RESULT OF CORROSIVE ENVIRONMENT MEASUREMENT

摘要

PROBLEM TO BE SOLVED: To provide a corrosive environment measurement method and a corrosive environment measurement system which allow a corrosion rate of a structure installed outdoors to be quantitatively and continuously recognized, and to provide a repair plan formulation method, the repair plan allowing repair to be performed at optimal timing in accordance with a degree of deterioration and an inspection plan formulation method, the inspection plan allowing a structure to be inspected at optimal timing in accordance with the progress of corrosion and deterioration.;SOLUTION: A sensor is arranged on a measurement object structure, the sensor having an inspection surface on which a pair of electrodes made of a material correlated to the measurement object structure with respect to corrosion resistance are spaced, and the change over time of impedance is measured at an arbitrary frequency within a frequency range allowing separation of resistance relating to ion conductivity of moisture stuck to the inspection surface and resistance of charge migration on surfaces of the electrodes.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
