摘要： Corrosion protection of steel in concrete is provided by locating an anode assembly including both a sacrificial anode and an impressed current anode in contact with the concrete and providing an impressed current from a power supply to the anode. The impressed current anode forms a perforated sleeve surrounding a rod of the sacrificial anode material with an activated ionically-conductive filler material between. The system can be used without the power supply in sacrificial mode or when the power supply is connected, the impressed current anode can be powered to provide an impressed current system and/or to recharge the sacrificial anode from sacrificial anode corrosion products.

摘要： A method of using and a steel reinforced concrete protector in an anode cavity which comprises a cored hole, a drilled hole or a cut chase formed in concrete. The protector comprises a sacrificial anode assembly and a separate backfill. The sacrificial anode assembly comprises a sacrificial metal element that is a metal less noble than steel and an activator to maintain an activity of the sacrificial metal element. The at least one spacer prevents the sacrificial metal element and the activator from contacting the surface of the anode cavity. The spacer and the sacrificial metal element have a coupling mechanism which facilitates connection of the sacrificial metal element to the spacer. The backfill is a pliable and viscous material which contains an electrolyte, and the backfill facilitates embedding the anode assembly in the anode cavity. The invention also relates to a prepackaged sacrificial anode assembly and a method of increasing a shelf life of the sacrificial anode.

摘要： The cathodic protection of a reinforced concrete structure utilizes sacrificial anodes such as aluminum or zinc as well as alloys thereof. Each anode is embedded or substantially covered in a material consisting of a hydrophilic non-cementious open-cell foam. An activating agent such as one or more lithium salts is contained within the cells of the foam to maintain the anodes in an electrochemically active state. The activating agent may be immobilized in the cells using an aqueous gel such as agar. One or more metallic conductors electrically connect the anodes to the metal reinforcing members.

摘要： Electrolytic protection of steel-reinforced concrete bodies such as bridges and building facades is achieved with carbon material inserted into the concrete body. The carbon material is connected to act as a anode with the steel reinforcement as a cathode, so that corrosive chloride ions migrate away from the steel reinforcement. The carbon material is inserted so as also to act as a reinforcement. In one arrangement carbon textile material is provided between inner and outer grout-filled plastics ducts fixed around post-tensioned steel cables. In another arrangement a carbon rod, or pin, is fixed between a concrete body and a steel I-beam.

摘要： 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.
