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： 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： 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 2 to receive a concrete repair material. Within this cavity 2 a smaller distinct cavity for assembling a sacrificial anode assembly and placing within this second cavity a pliable viscous ionically conductive backfill, a sacrificial anode and an activating agent to form a sacrificial anode assembly 5. This assembly 5 is connected to the steel 6. The anode and the backfill in the second cavity are covered 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. The backfill may comprise a lime putty.

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： 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： 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].
