In an effort to acquaint field personnel with the theory of cathodic protection and assist in the design, construction and operation of a cathodic protection system, a demonstration project is being offered which will include an introductory slide presentation, assistance in development of a work plan and work schedule, assistance in locating material sources, assistance in the electronic circuitry and system design, and assistance during construction and post construction evaluation periods. Cathodic protection involves the external application of a direct current to the surface of the top mat of steel in sufficient amounts to overcome the internal current flow between the anode and cathode. A sacrificial anode is provided and allowed to corrode and the reinforcing steel becomes the cathode. Cathodic protection (CP), has been used for many years to control corrosion of buried pipe lines and structures in salt water environments, to protect piers, pilings and other underground installations. Promising results have been obtained in test installations of CP systems on bridge decks to control corrosion of the reinforcing steel.
