Abstract: Cathodic protection of an existing concrete structure, including a steel member at least partly buried, such as steel rebar, in the concrete structure, is provided by embedding anodes into a fresh concrete layer applied over an excavated patch and/or as a covering overlay. The anodes are embedded at spaced positions or as an array in the layer and connected to the rebar. A corrosion inhibitor is added into the fresh concrete at least at the interface and more preferably in admixture with the fresh concrete which acts to reduce the flow of ionic current to the steel or between the anode member and the steel in the fresh covering material without significantly increasing the resistivity of the fresh covering material and without inhibiting the ionic current between the anode member and the fresh covering material. In this way the current to the steel in the existing concrete is maximized to maximize the cathodic protection to the existing steel which is the primary target.
Abstract translation: 通过将阳极嵌入施加在挖掘的贴片和/或覆盖层上的新混凝土层中来提供在现有混凝土结构中的阴极保护，包括在混凝土结构中至少部分埋设的钢构件（例如钢筋）。 阳极嵌入在层间的间隔位置或阵列上，并与钢筋连接。 至少在界面处将新的混凝土中的腐蚀抑制剂加入到新混凝土中，更优选与新鲜的混凝土混合，这些混凝土的作用是减少离子电流向新鲜的覆盖材料中的钢或阳极构件和钢之间的流动，而不会明显 增加新鲜覆盖材料的电阻率，并且不会抑制阳极构件和新鲜覆盖材料之间的离子电流。 以这种方式，现有混凝土中的钢的电流最大化，以使作为主要目标的现有钢的阴极保护最大化。

Abstract: Steel reinforcing cables in concrete are protected against corrosion by injecting a carrier fluid and corrosion inhibitors into interstitial spaces between the wires of the cable at a first location along the cable and causing the fluid to pass through the interstitial spaces between the wires of the cable to a second location along the cable. The cable comprises an array of wires confined together and intimately surrounded by a covering material which is engaged with a periphery of the cable so that there are insufficient interconnected spaces between the cable and the covering material to allow passage of fluid longitudinally along the cable outside the cable itself. The method can be used with pre-stressed concrete, with post-tensioned bonded cables and with extruded un-bonded mono-strand cables.

Abstract: Cathodic 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: An anode for use in cathodic protection of steel in concrete is formed from an electrically conductive material such as zinc and an ionically conductive material which is preferably a humectant and/or has a pH greater than 12 to enhance current flow. The materials are intimately intermixed through at least a part of the anode body and compressed into the anode body with an electrical connecting lead formed into a core of the body which is wholly conductive material. Portions of the electrically conductive material are pressed into electrical contact to form a plurality of electrically conductive paths within the anode body. Many of the voids in the body are interconnected to form a plurality of ionically conductive paths through the anode body by causing the humectant to migrate through the voids. The large surface area between the ionically conductive paths and the electrically conductive paths increase significantly the contact surface area of the anode body to increase current flow.

Abstract: Cathodic protection of a structure including a steel member at least partly buried in a covering layer, such as steel rebar in a concrete structure, is provided by embedding sacrificial anodes into the concrete layer at spaced positions over the layer and connecting the anodes to the rebar. The anode body is formed, by pressing together finely divided powder, flakes or fibers of a sacrificial anode material such as zinc to define a porous body having pores therein. The sacrificial anode material of the anode member is directly in contact with the covering material by being buried or inserted as a tight fit into a drilled hole so that any expansion forces therefrom would be applied to the concrete with the potential of causing cracking. The pores are arranged however such that corrosion products from corrosion of the anode body are received into the pores sufficiently to prevent expansion of the anode body to an extent which would cause cracking of the covering material.
