摘要： The deterioration of reinforced concrete structures by galvanic corrosion is a well understood problem, particularly as it affects roads, bridges, parking garages and buildings that use reinforcing steel in their construction. Galvanic cathodic protection is typically provided for such reinforced concrete structures using embedded sacrificial anodes, such as zinc, aluminum, and alloys thereof. Disclosed herein is an anode assembly (10) for cathodic protection of a reinforced concrete structure. The assembly comprises at least one sacrificial anode member (12). The anode member is covered with an ionically-conductive covering material (14) into which is bound an electrochemical activating agent at least partly covering the sacrificial anode member. One side (26) of the ionically-conductive covering material is configured to conform closely and securely to a steel reinforcing bar. The conforming side has a non-conductive barrier (16) as an integral part of the covering material. An electrical connection is established between the anode member and a ferrous reinforcing bar (20) using conductive wires (18).

摘要： The galvanic cathodic protection of reinforced concrete structures such as bridges, buildings, parking structures, piers, and wharves, is enhanced by the use of an inert water absorbent solid. The absorbent solid and chemicals are mixed with a cementitious binder to form an activating matrix. This matrix surrounds a sacrificial metal anode such as zinc, or aluminum or their alloys. The metal anode is electrically connected to the ferrous reinforcing member by a metallic conductor. The water absorbent solid may be a clay such as bentonite or a hydrated mineral such as vermiculite. It is preferably in the form of discrete particles dispersed throughout the binder. The inclusion of the absorbent solid in the activating matrix serves to increase the protective current, thereby reducing corrosion of the reinforcing components of the concrete structure.
