PROPOSED CORROSION CONTROL METHOD USING CORROSION RATE OF STEEL IN CONCRETE UNDER CATHODIC PROTECTION

Abstract

 A corrosion protection management method was proposed using the corrosion rate of steel in concrete under cathodic protection as a control index. Experimental results using test specimens showed that the proposed method was able to control corrosion protection in the same way as the depolarization control method. The power consumption of the proposed method is smaller than that of the depolarization control method, and it is considered to be an economically effective control method.
