A corrosion resistant connection that does not require any further protective insulation can be formed using titanium conductors [2,6] and connecting the conductors together at a conductor-conductor connection [5] using a clamping device comprising a non-metallic material wherein the clamping device only brings corrosion resistant material into contact with the conductors.

Abstract: A steel reinforced concrete protector in an anode cavity such as a cored hole, drilled hole or cut chase is disclosed. The protector includes a sacrificial anode assembly and a separate backfill. The sacrificial anode assembly includes a sacrificial metal element and an activator to maintain an activity of the sacrificial metal element and at least one spacer. The 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 fills the spaces between the sacrificial anode assembly and the anode cavity wall. The invention also relates to a pre-packaged sacrificial anode assembly to increase the shelf life of the assembly.

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: A method of protecting steel in concrete is disclosed. A voltage between two connections of a power supply is generated such that current can flow between a negative connection and a positive connection. In a first protection step, one of the connections of the power supply is electrically connected to the steel to be cathodically protected and a sacrificial anode is electrically connected in series with the other connection of the power supply such that the voltage generated by the power supply is added to the voltage generated between the sacrificial anode and the steel to produce a voltage greater than the voltage generated between the sacrificial anode and the steel alone. The power supply may be a cell or battery and may be combined with the sacrificial anode to form a single unit. In a second protection step that may follow the first protection step, the voltage generated by the power supply is no longer present and a current flows between the sacrificial anode and the steel to continue protecting and/or passivating the steel. This may be achieved by connecting the sacrificial anode directly to the steel.

Abstract: 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 (4) and a backfill (3) and a tape (5) and an adhesive to protect steel (8) in concrete. The backfill is preferably placed in a shallow cavity (1) in the concrete surface (2) 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.

Abstract: 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.

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.
