(1) Metal anodes for mitigating the corrosion of reinforcing steel in concrete.

Abstract

In a method for cathodically protecting and/or passivating a metal section in an ionically conductive material such as steel reinforcement in concrete or mortar, an impressed current or sacrificial anode communicates electrical current to the metal section and a storage component of electrical energy which can be a cell, battery or capacitor is provided as a component of the anode. The storage component can have replacement energy introduced by re-charging or replacing the component from an outside supply. Typically the cell or storage capacitor has an outer case which carries an anode material as an integral outer component.

IPC Classes  ?

• C23F 13/20 - Conducting electric current to electrodes
• C23F 13/06 - Constructional parts, or assemblies of cathodic-protection apparatus

Abstract

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.

Abstract

Cathodic protection of steel in a concrete column in sea water is simplified by providing a pre-assembled unit including a jacket to surround the column carrying a bulk sacrificial anode outside the jacket and optionally an inner sacrificial anode of a zinc mesh or strips on an inside surface. The jacket can also include a pre-assembled junction box and couplings to connect to the steel. The jacket is attached to the surface of the column at the water line so that the bulk anode is located below the surface of the water and supported relative to the concrete surface solely by the connection of the bulk anode to the covering layer. The bulk anode can be formed of aluminum so as to be less toxic in sea water.

Abstract

Cathodic protection of steel in a concrete column in sea water is simplified by providing a pre-assembled unit including a jacket to surround the column carrying a bulk sacrificial anode outside the jacket and optionally an inner sacrificial anode with a cast grout inside the jacket. The jacket can also include a pre-assembled junction box and couplings to connect to the steel. The jacket is attached to the surface of the column at the water line so that the bulk anode is located below the surface of the water. The bulk anode can be formed of aluminum so as to be less toxic in sea water. An activator is applied inside the jacket either as a wicking layer or as a chemical activating material. The jacket can act only as a form work which is then removed after casting of the grout.

Abstract

An anode apparatus for mounting on an external surface of a concrete structure to provide cathodic protection of metal members in the concrete uses a pre-assembled body which is typically elongate carrying a longitudinal anode, which can be sacrificial or impressed current, together with a supporting material having a front face for attachment to the surface and an impermeable plastic covering material at the rear face covering the anode and the supporting material when the front face is attached to the surface of the concrete. A channel defined on the front face is arranged to receive a layer of a conformable ionically conductive adhesive material for attachment to the external surface. A distance of the edge of the covering material is arranged to be similar to a distance of the metal from the external surface such that wetting and drying effects of environmental moisture are the same for the anode as for the metal components.

Abstract

Cathodic protection of steel in a building or other concrete or similar
structure is provided by locating an anode in a suitable location adjacent to
the steel
and providing an impressed current from a power supply to the anode. The anode
is
formed from a material which is more electro-negative than the steel so that
in the event
that the power supply falls below the galvanic potential therebetween, current
flows
under galvanic action to replace the impressed current. A diode in the circuit
prevents
flow of current across the power supply but allows the galvanic current when
the power
supply fails open circuit. An additional diode can be provided in the event
the power
supply fails closed circuit to prevent reverse current flow.
