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： 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.

摘要： A method and a steel reinforced concrete protector in an anode cavity which comprises a cored or drilled hole or a cut chase formed in concrete. The protector comprises a sacrificial anode assembly and a separate backfill. The sacrificial anode assembly comprises a sacrificial metal element less noble than steel and an activator to maintain an activity of the sacrificial metal element. The at least one spacer prevents the sacrificial metal element and the activator from contacting 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 the backfill facilitates embedding the anode assembly in the anode cavity. A prepackaged sacrificial anode assembly and a method of increasing a shelf life of the sacrificial anode is also covered.

摘要： The galvanic cathodic protection of steel embedded in concrete structures is enhanced by the utilization of a flexible composite anode assembly containing a sacrificial anode member. The anode member is at least partially covered by a matrix comprising an ionically-conductive material. The conductive material includes at least one electrochemical activating agent such as a mixture of lithium bromide and lithium nitrate and a compressible water-retaining mineral such as a phyllosilicate mineral. The presence of this mineral in the matrix increases the current delivered by the anode, thereby resulting in a greater level of cathodic protection, and a longer effective service life of the anode. Exfoliated vermiculite is a preferred phyllosilicate mineral and is present in an amount of between about 2% and about 15% by weight, based on the total weight of the matrix.
