Abstract: This invention is a device that provides a multi use cathodic protection system for steel and reinforced concrete and method of use that will permit a user to more easily and accurately place an impressed current cathodic protection system, a sacrificial or galvanic anode cathodic protection system, or combination thereof around a reinforced structure to be protected and thereafter fill with concrete by use of a uniquely engineered fiberglass reinforced plastic form. This invention once put in place around the structure being protected can more easily be filled with concrete without having the attached titanium mesh or zinc anode mesh bend or move outside of the effective proximity from the protected structure. The fiberglass reinforced plastic form has a corrugated or roughed surface that provides an increased surface area to bind or grip the fiberglass reinforced plastic form to the poured concrete once cured.

Abstract: Cathodic protection of a structure including a steel member at least partly buried in a covering layer, such as steel rebar in a concrete structure, is provided by embedding sacrificial anodes into the concrete layer at spaced positions over the layer and connecting the anodes to the rebar. The anode body is formed, by pressing together finely divided powder, flakes or fibers of a sacrificial anode material such as zinc to define a porous body having pores therein. The sacrificial anode material of the anode member is directly in contact with the covering material by being buried or inserted as a tight fit into a drilled hole so that any expansion forces therefrom would be applied to the concrete with the potential of causing cracking. The pores are arranged however such that corrosion products from corrosion of the anode body are received into the pores sufficiently to prevent expansion of the anode body to an extent which would cause cracking of the covering material.

Abstract: An improved sacrificial galvanic anode assembly for cathodic protection of a steel reinforced concrete structure. A galvanic cathodic protection device uses an embedded sacrificial anode of metallic foam for increased reactive surface area covered with a flexible penetrating coating to provide a continuous electrolyte to keep it active. The formulated coating paste is inert to cement embedment material and is pre-applied on the anode body prior to encapsulation. An integrated conductive contact band extends from the coated anode to attachment to a reinforcement bar for establishing electrical conductively therewith within the concrete structure transferring galvanic corrosion to the anode.
