摘要： The use of an electric field modifier to boost the current output of a discrete sacrificial anode to enhance its protective effect and to direct the current output in a preferred direction to improve current distribution in the galvanic protection of steel in hardened reinforced concrete elements exposed to the air is disclosed. In one method a combination comprising a sacrificial anode (21) and an electric field modifier (25) and an ionically conductive filler (28) is embedded in a cavity formed in a concrete element and the sacrificial anode is directly connected to the steel (22). The modifier comprises an element with a side that is an anode (27) supporting an oxidation reaction in electronic contact with a side that is a cathode (26) supporting a reduction reaction. The cathode of the modifier faces the sacrificial anode and is separated from it by the filler (28). The filler 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. The reduction reaction on the cathode of the modifier may substantially comprise the reduction of oxygen from the air.

摘要： 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.

摘要： A method of monitoring the protection delivered to steel bars (1) in concrete construction protected by a discrete sacrificial anode cathodic protection system comprising measuring potentials at potential measurement points located at close intervals in a representative area while the installed sacrificial anodes (2) are operating wherein the potential measurement points include at least three points (3) all located between but away from the same nearby installed anodes (2) and are all preferably located between the same pair of adjacent parallel steel bars. The results are used to identify the position of local anodes. The identification of anodes at locations where none are installed indicates that the steel may not be protected and the discrete sacrificial anode cathodic protection system is not operating effectively.

摘要： A sacrificial anode assembly (1) for cathodically protecting and/or passivating a metal section, comprising: (a) a cell, which has an anode (2) and a cathode (3) arranged so as to not be in electronic contact with each other but so as to be in ionic contact with each other such that current can flow between the anode and the cathode; (b) a connector (6) attached to the anode of the cell for electrically connecting the anode to the metal section to be cathodically protected; and (c) a sacrificial anode (7) electrically connected in series with the cathode of the cell; wherein the cell is otherwise isolated from the environment such that current can only flow into and out of the cell via the sacrificial anode and the connector. The invention also provides a method of cathodically protecting metal in which such a sacrificial anode assembly is cathodically attached to the metal via the connector of the assembly, and a reinforced concrete structure wherein some or all of the reinforcement is cathodically protected by such a method.

摘要： A method of using an activator in a compact discrete sacrificial anode assembly that is assembled within an anode cavity in concrete is described. The method includes providing a sacrificial anode, and an activator to activate the sacrificial anode, and a backfill to embed the sacrificial anode and the activator in an anode cavity in the concrete. The activator is provided as a discrete contained unit for dispersion through the backfill to surfaces of the sacrificial anode, and the unit at least in part separates the activator from any electrolyte in contact with the sacrificial anode. The activator is separated from the backfill prior to use. The advantages of this invention include limiting corrosion of the sacrificial metal element prior to use, containment of the health and safety risk presented by an activator, and providing a facility to control the quantity of activator installed in a sacrificial anode assembly. A surprising benefit results from a transient increase in the temperature of the assembly.

摘要： A method of protecting steel in concrete using a sacrificial anode assembly is disclosed. The sacrificial anode assembly comprises a sacrificial metal element (11), an activator, a backfill (13), a connector (17) and a spacer (12). An anode cavity (14) is formed in the concrete for the purposes of installing the sacrificial anode assembly therein. The sacrificial metal element and activator are embedded in the backfill in the cavity. The spacer holds the activator away from the sides of the cavity. The connector is used to connect the sacrificial metal element to the reinforcing steel (16). The backfill is a pliable, viscous backfill that does not harden before the installation process is completed.

摘要： 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 attached to the concrete surface tend to lose adhesion to the concrete. The use of a discrete sacrificial anode (4) and a backfill (3) and a tape (5) and an adhesive to protect steel in concrete. The backfill is preferably placed in a shallow cavity in the concrete surface and the sacrificial anode is inserted into the backfill. The cavity is covered with a tape that extends over the adjacent concrete surfaces on opposite sides of the sacrificial anode and backfill and the tape is attached to the concrete surface with the adhesive. The tape and the adhesive holds the anode in place and prevents a weathering environment from damaging the backfill.

摘要： High performance cementitious concretes or mortars and bonding agents developed for use as patch repair materials for corrosion damaged concrete often have high resistivities that inhibit the performance of sacrificial anodes located within patch repair areas. A method of repair is disclosed that comprises removing the corrosion damaged concrete to expose steel and form a cavity to receive high performance concrete repair materials and forming within the parent concrete exposed in this cavity a smaller distinct cavity for assembling a sacrificial anode assembly and placing within this anode 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 assembly in the anode 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
