摘要： 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.

摘要： Corrosion of steel in a concrete structure such as a column in sea water occurs primarily above the water line and is inhibited using cathodic protection by attaching to the column an impervious sealed sleeve in which is provided a sacrificial anode in sheet form in contact with a layer of water transport medium so that water from the location of the bottom of the water transport medium within the water is carried into the area of the sacrificial anode to enhance ionic current.

摘要： 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.

摘要： Humectants are applied to cathodic protection systems which utilize thermally-sprayed zinc or zinc alloy anodes applied to the surface of reinforced concrete structures. The humectants are deliquescent or hygroscopic organic or inorganic salts, hydrophilic polymers or colloids, or organic liquid desiccants. The humectants are positioned at or near the interface between the anodes and the concrete and increase the moisture content at the interface. This increases the ability of the anode to deliver cathodic protection current to steel embedded in the concrete. The humectants may be applied to the concrete surface prior to application of the anode, or may be applied subsequent to installation of the anode.
摘要翻译：保湿剂适用于阴极保护系统，其利用施加到钢筋混凝土结构表面的热喷锌或锌合金阳极。湿润剂是潮解性或吸湿性的有机或无机盐，亲水性聚合物或胶体，或有机液体干燥剂。保湿剂位于阳极和混凝土之间的界面处或附近，并增加界面处的含水量。这增加了阳极将阴极保护电流输送到嵌入混凝土中的钢的能力。在施加阳极之前，保湿剂可以施加到混凝土表面，或者可以在安装阳极之后施加。

摘要： A method for providing cathodic protection for a metallic structure in contact with the ground, for example, a pipeline, comprises disposing a suitable anode at depth in a borehole so that the anode is disposed generally opposite a preselected ground zone or stratum of relatively low electrical resistivity. A liquid electrolyte which is operatively compatible with both the surrounding ground and with the anode is provided in the borehole and may comprise naturally occurring ground water which may optionally be modified, for example, by the addition of an ionizable salt.

摘要： A method for producing cathodic protection for protecting reinforcing steel (2) in a reinforced concrete structure (1) is provided, in which reinforced concrete structures subjected to chloride-induced corrosion can be simply and durably protected against corrosion. Furthermore, the cathodic protection is also intended to be producible particularly quickly both for new buildings as well as when carrying out renovation/retrofitting work. For this purpose, a textile-reinforced concrete (8) is applied to the reinforced concrete, wherein the textile-reinforced concrete (8) comprises a carbon fabric (10) and a mortar, wherein a continuous electrical voltage is applied between a cathode and an anode and wherein the reinforcing steel (2) is used as the cathode and the carbon fabric (10) is used as the anode.
