ABSTRACT
Corrosion of steel in concrete is an electrochemical process and electrochemical techniques have been used to control corrosion. The simplest of these techniques is galvanic protection. In this case a galvanic anode is connected to the steel and the anode corrodes while delivering a protection current to the steel. Another technique is a hybrid treatment in which a high protection current is briefly impressed off a galvanic anode before galvanic protection is applied (Holmes et al. 2011a). This work looks at data from such systems and considers their performance.
