NON-DESTRUCTIVE CORROSION DIAGNOSIS SYSTEM BY THE ESTIMATION OF ELECTRICAL RESISTIVITY IN CONCRETE STRUCTURES

摘要

PURPOSE: A non-destructive corrosion diagnosis system using electrical specific-resistivity estimation of a concrete structure is provided to evaluate the corrosion of a reinforcing rod by estimating the resistivity of the steel reinforcement surface by using a nondestructive method. CONSTITUTION: A non-destructive corrosion diagnosis system using electrical specific-resistivity estimation of a concrete structure comprises an electrode part(40), a controller(10), and a measuring device part(20), and a connection part(30). The electrode part comprises a voltage electrodes and current electrodes(41). The controller monitors the measurement result by using a monitor in real time. The connection part respectively and electrically connects the controller and the measuring device part.
