Abstract
Cathodic protection of concrete-reinforcing steel reinforcing elements is accomplished utilizing an anode of a metal (e.g. zinc) having a more negative electrical potential than the steel reinforcing element, and connecting at least one wire made of a ductile metal to the anode. The anode may be cast around the wire, or a twisted portion of two or more wires. The wires are wrapped around one or more of the reinforcing elements and electrically and physically connect the anode to the reinforcing elements. The cathodic protection is maintained over a sustained period of time by casting a cementitious material around the anode, e.g. a mortar containing an electrolyte solution having a pH of at least about 14 when the anode is zinc.
