Abstract: An improved sacrificial galvanic anode assembly for cathodic protection of a steel reinforced concrete structure. A galvanic cathodic protection device uses a multi-layered embedded sacrificial anode such as zinc covered with a flexible layer of paste to provide a continuous electrolyte to keep it active. The formulated paste is inert to cement embedment material and is pre-coated on the anode body prior to encapsulation. An integrated conductive contact band extends from within the coated anode to attachment to a reinforcement bar for establishing electrical conductively therewith in the concrete structure transferring galvanic corrosion to the anode.

Abstract: A single anode system used in multiple electrochemical treatments to control steel corrosion in concrete comprises a sacrificial metal that is capable of supporting high impressed anode current densities with an impressed current anode connection detail and a porous embedding material containing an electrolyte. Initially current is driven from the sacrificial metal [1] to the steel [10] using a power source [5] converting oxygen and water [14] into hydroxyl ions [15] on the steel and drawing chloride ions [16] into the porous material [2] around the anode such that corroding sites are moved from the steel to the anode restoring steel passivity and activating the anode. Cathodic prevention is then applied. This is preferably sacrificial cathodic prevention that is applied by disconnecting the power source and connecting the activated sacrificial anode directly to the steel.

Abstract: A method of protecting steel in concrete is disclosed. It consists of connecting the steel (6) to a discrete sacrificial anode assembly (7) comprising a base metal (1), a relatively small quantity of catalytic activating agent in contact with the base metal and a substantially inert porous layer (3) that surrounds the base metal and catalytic activating agent. The inert porous layer efficiently maintains a sustainable concentration gradient of the catalytic activating agent between the base metal and the surrounding environment as a result of the electric field across this layer. The preferred porous layer comprises a material that exhibits a net repulsion of negative ions from its pore system and the preferred catalytic activating agent comprises doubly charged sulphate ions as small electric fields maintain very high concentration gradients of these ions resulting in high concentrations at the base metal surface and insignificant concentrations at the assembly periphery.

Abstract: This assembly provides a flexible method of attaching discrete sacrificial anodes to exposed steel in concrete construction to achieve an advantageous distribution of protection current. It comprises a base metal [1] that is less noble than steel, a conductor [6] connected to the base metal, a tying point [2] formed at least in part by the conductor, and a tie [4] that passes through the tying point [2] and around the steel [5]. The tie is used to physically tie the anode between steel bars prior to placing the concrete and in the process to electrically connect the anode to the steel. The tying point is open to facilitate adjusting the tie. The separation of the tie from an anode assembly with a tying point allows the tie to be selected during installation when the properties required by the application are known.

Abstract: The installation and use of embedded sacrificial anodes to protect reinforced concrete may be improved. In one example a cavity [2] is formed in the concrete [3] and a puttylike backfill [4] is placed in the cavity and a compact discrete anode comprising a sacrificial metal element [1] is inserted into the backfill and a space is provided into which the backfill may move when subjected to a pressure arising from the formation of voluminous sacrificial metal corrosion products and a high current is passed from the anode to the steel in the concrete to arrest steel corrosion and activate the anode in the backfill. The space may be provided by venting the backfill to space outside the cavity through an opening [5] or by including a void space within the backfill [6] or a void space within the cavity [7].

Abstract: An anode for use in cathodic protection of steel in concrete is formed from an electrically conductive material such as zinc and an ionically conductive material which is preferably a humectant and/or has a pH greater than 12 to enhance current flow. The materials are intimately intermixed through at least a part of the anode body and compressed into the anode body with an electrical connecting lead formed into a core of the body which is wholly conductive material. Portions of the electrically conductive material are pressed into electrical contact to form a plurality of electrically conductive paths within the anode body. Many of the voids in the body are interconnected to form a plurality of ionically conductive paths through the anode body by causing the humectant to migrate through the voids. The large surface area between the ionically conductive paths and the electrically conductive paths increase significantly the contact surface area of the anode body to increase current flow.

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 translation: 包括至少部分地埋在覆盖层中的钢构件（例如混凝土结构中的钢筋）的结构的阴极保护是通过在层上的间隔位置将牺牲阳极嵌入混凝土层中并将阳极连接到钢筋来提供的 。 阳极体通过将细分散的粉末，诸如锌等牺牲阳极材料的薄片或纤维压在一起形成，以限定其中具有孔的多孔体。 阳极部件的牺牲阳极材料通过被埋入或插入钻孔中而直接与覆盖材料接触，从而将其中的任何膨胀力施加到具有引起裂纹的可能性的混凝土中。 然而，孔被布置成使得阳极体的腐蚀产生的腐蚀产物被充分地容纳到孔中，以防止阳极体膨胀到使覆盖材料破裂的程度。

Abstract: The invention relates to a galvanic anode system for the corrosion protection of steel, comprised of a solid electrolyte and a galvanic anode material, preferably zinc and its alloys, glued to the solid electrolyte or embedded in the solid electrolyte. The solid electrolyte is characterised by a high ion conductivity and comprises at least one anionic and/or cationic polyelectrolyte and/or preferably at least one compound that forms complex compounds with the anode material, preferably with zinc. The solid electrolyte is produced by applying a coating agent, preferably as an aqueous dispersion or suspension, to the steel and/or to the mineral substructure, preferably to concrete. The anode material is characterised in that it forms a galvanic element in combination with the solid electrolyte and the steel to be protected, in which the steel forms the cathode. The inventive galvanic anode system is further characterised in that the anode material is applied to the surface of the solid electrolyte as a foil, network or grid, preferably by gluing, and/or is embedded in the solid electrolyte.
