Abstract: There is described a method of cathodic protection, electrochemical chloride extraction and realkalisation in reinforced concrete or similar materials, and also reinforcement and crack prevention in concrete (1), comprising the impressing of a direct voltage between the reinforcement in the concrete (1) and a conductive device which is brought into contact with the surface of the concrete (1), and wherein the crack preventing effect is obtained by embedding the device in fresh concrete. The method is characterised in that as conductive device/current distributors there is used a mat (3) of optionally coated, conductive carbon fibers produced by blowing, pressing, weaving or knitting so that the fibers lie in almost every direction, and wherein the fibers are of different thickness, wherein the mat further comprises electric conductors (4) in the form of bands or wires of conductive material which are placed over or under the mat (3) or are incorporated therein.
