Zinc, aluminum, and several aluminum alloys were tested as anodes in contact with hydrogel adhesives. Zinc was found to offer the best combination of working potential, resistance to passivation, cost, and availability. Several hydrogels used for medical applications were found to be inadequate for this use, but a hydrogel adhesive was developed specifically to bond sacrificial anodes to concrete. This hydrogel achieve a total charge in accelerated testing equal to 12 years of life at current densities normally used for cathodic protection (CP).
