Zusammenfassung:	A grid electrode for cathodic protection of steel rebar reinforced concrete structures comprising a plurality of valve metal strips having voids with an electrocatalytic surface and 2,000 to 7,000 nodes per square meter electrically conncected together to form a grid and a method of cathodically protecting steel rebar reinforced concrete structures comprising impressing a constant anodic current upon a grid made up by a plurality of valve metal strips with voids with an electrocatalytic surface and 2,000 to 7,000 nodes per square meter embedded in a steel reinforced concrete structure containing 0.5 to 5 square meters of steel surface for each square meter of concrete surface with the ratio of electrode surface to the steel surface density being selected to maintain a uniform cathodic protection current density throughout the concrete structure.
