Abstract

An anode (20) for protecting a reinforced concrete structure by impressed-current cathodic protection is formed of two sheets (21, 22) of polymer matrix such as polypropylene having a filler of Fe-Ti, TiOx or TiO2 or mixtures thereof to render the anode conductive. The anode may be in the form of a tile formed from two sheets (21, 22) with an electrical conductor (23) therebetween. The tile has apertures (26) to permit concrete or grout to bond to an underlying concrete surface (33).
