Patent ID: 8366904

Claim:
A method for use in cathodic protection of a steel member in a cementitious covering material, the method comprising: providing an anode body at least partly formed from a sacrificial anode material of a character which corrodes relative to the steel member to form corrosion products; locating the anode assembly at least partly in contact with the cementitious covering material; and electrically connecting the anode assembly to the steel member so that an electrical galvanic potential therebetween causes corrosion of the sacrificial anode material and tending to inhibit corrosion of the steel member; providing at least a portion of the anode assembly which comprises porous material; including an additive enhancement material within said at least a portion of the anode assembly which is porous; and causing the corrosion products formed by the corroding of the sacrificial anode material to be at least partly soluble by including in said at least a portion said enhancement material which assists in forming said corrosion products as soluble corrosion products.
