51317--9700-Galvanic Cathodic Protection for High Resistance Concrete in Marine Environments

Picture for Galvanic Cathodic Protection for High Resistance Concrete in Marine Environments
Available for download

For reinforced concrete (RC) structures that are in drier locations but still need of cathodic protection (CP), impressed current cathodic protection (ICCP) systems are preferred. In this study, the performance of activated zinc anodes installed on dry or high resistance concrete on Florida Bridges was evaluated.

The good performance of galvanic cathodic protection (GCP) systems is well proven and recognized for the protection of corrosion related damage on reinforced concrete (RC) structures located in marine environments. However these cathodic protection systems are typically installed in areas where the concrete has a high chloride and moisture content. It has been observed that typically in dry conditions galvanic anodes either passivate or do not maintain a voltage potential sufficient to drive the CP current. On the contrary for these dry areas impressed current cathodic protection (ICCP) systems are preferred due to their higher voltages and their ability to force the currents. This paper discusses the installation and performance of galvanic cathodic protection systems using pre-activated zinc anodes installed over dry concrete on bridges in Florida.

Key words: activated mortar, activator, anode, cathodic protection, chlorides, continuity, CP jacket, galvanic, high resistance, marine environments, passivate, polarization, reference electrode, reinforced concrete, voltage potential
