Abstract
In order to evaluate the possible application of a galvanic sensor for cathodic protection (CP) and straycurrent monitoring of steel embedded in concrete structures, the correlation of sensor current to protection abilities (protection potential/current) and stray-current was investigated by galvanostatic tests that simulated the CP and stray-current. The results revealed a good correlation between the sensor current and the protection abilities or stray-current in terms of the sign as well as magnitude. Thus, the galvanic sensor is proposed as an effective tool for the quantitative determination of the effectiveness of CP or of the interference effect of stray-current.
