Abstract
A low-cost method for galvanic cathodic protection of reinforcing steel in concrete was examined. In this method, arc-sprayed zinc is deposited on the external concrete surface of steel-reinforced marine substructure bridge components, which are normally subject to corrosion of the reinforcement as a result of chloride ion contamination of the concrete. In this investigation, the ability of the system to deliver protective current was examined by experiments in the laboratory and at field installations at bridges in the Florida Keys.
