Corrosion-caused distress to reinforcedconcrete structures is a serious and continuing problem. A practical mitigation measure is cathodic protection of the embedded reinforcing steel. In this paper the results of an ongoing laboratory and field study that tests proprietary conductive paints and flame-spray metallizing as conductive coatings/anodes on concrete are described, and their physical characteristics, behavior, and economics as part of cathodic protection systems are also discussed. Results to date indicate that several of the paints and most of the metals tested provide adequate conductivity and bond to the concrete, but differ significantly in ease of application, toxicity, aesthetics, and economics. Of the materials tested, zinc metallizing appears to provide the most viable combination of physical characteristics and economics for cathodic protection of concrete reinforcement.
