20090229994 | DISCRETE SACRIFICIAL ANODE ASSEMBLY - Sacrificial anode assemblies have the advantage that they can provide galvanic protection to steel in concrete and do not require long term maintenance of a DC power supply. However sacrificial anode assemblies often loose adhesion to the concrete surface. This invention discloses the use of a sacrificial anode ( | 09-17-2009 |
20090236764 | Sacrificial Anodes in Concrete Patch Repair - High performance proprietary cementitious concretes or mortars developed for use as patch repair materials for corrosion damaged concrete often have high resistivities that inhibit the performance of sacrificial anodes located within the patch repair areas. A method of repair is disclosed which comprises removing the corrosion damaged concrete to form a cavity to receive a concrete repair material and forming within this cavity a smaller distinct cavity for assembling a sacrificial anode assembly and placing within this second cavity a pliable viscous ionically conductive backfill and a sacrificial anode and an activating agent to form a sacrificial anode assembly and connecting the anode to the steel and covering the anode and the backfill in the second cavity with a repair material to restore the profile of the concrete structure. In this arrangement a high resistivity repair material promotes the flow of protection current to steel in adjacent contaminated concrete that is at risk of corrosion. | 09-24-2009 |
20100314262 | CORROSION PROTECTION OF STEEL IN CONCRETE - An electric field modifier for boosting a current output of a sacrificial anode to enhance its protective effect and direct the current output to improve current distribution in galvanic protection of steel in a concrete element exposed to air is disclosed. A cavity is formed in a concrete element and a combination comprising a sacrificial anode, an electric field modifier and an ionically conductive filler are embedded therein. The sacrificial anode is connected to the steel. The modifier comprises an element with an anode side, supporting an oxidation reaction, in electrical contact with a cathode side, supporting a reduction reaction. The cathode of the modifier faces the sacrificial anode and is separated therefrom by a filler which contains an electrolyte that connects the sacrificial anode to the cathode of the modifier. The anode of the modifier faces away from the sacrificial anode. Preferably, the reduction reaction, on the cathode of the modifier, comprises reduction of oxygen from the air. | 12-16-2010 |
20130020191 | CORROSION PROTECTION OF STEEL IN CONCRETE - An electric field modifier for boosting current output of a sacrificial anode for reinforced concrete to enhance its protective effect and direct the current output in a preferred direction to improve current distribution in galvanic protection of steel exposed to air. The combination comprises a sacrificial anode and an electric field modifier and an ionically conductive filler embedded in a cavity and the sacrificial anode is directly connected to the steel. The modifier comprises an element with an anode side supporting an oxidation reaction in electronic contact with a cathode side supporting a reduction reaction. The cathode of the modifier may form a cell with the sacrificial anode and is separated therefrom by the filler. The filler contains an electrolyte that connects the sacrificial anode to the cathode of the modifier. The reduction reaction on the cathode of the modifier may substantially comprise the reduction of oxygen from the air. | 01-24-2013 |
