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: In a method of corrosion protection of rebar in concrete the sacrificial anode is held in place by wrapping a first wire around a first rebar portion and a second wire at second rebar portion and twisting together the first and second free ends to tension the wrappings. This can be used either on two separate rebars which are parallel or at right angles or can be used at longitudinally spaced positions on a single rebar where the rebar roughening prevents the two wrappings from sliding as the wires are tensioned by the twisting. In many cases a covering material such as a porous mortar is cast onto the outer surface of the anode and in this case the mortar and the wire are located such that the wire exits from the sacrificial anode at a position separate from the layer of covering material.
Abstract translation: 在混凝土中钢筋的防腐蚀方法中，通过在第一钢筋部分围绕第一钢筋部分和第二钢丝缠绕第一钢丝并将第一和第二自由端扭曲在一起以张紧包装来将牺牲阳极保持就位。 这可以在平行或直角的两个单独的钢筋上使用，或者可以在单个钢筋上的纵向间隔位置使用，其中钢筋粗糙防止当钢丝被扭转拉紧时两个包皮滑动。 在许多情况下，诸如多孔砂浆的覆盖材料被浇铸到阳极的外表面上，并且在这种情况下，砂浆和电线被定位成使得电线在与覆盖材料层分开的位置处从牺牲阳极离开 。

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.
