Abstract

An assembly for use in the cathodic protection of steel reinforcement in reinforced concrete said assembly comprising; 1) an anode of a metal having a more negative electrode potential than steel and, in electrical contact therewith; 2) an elongated electrical connector made of a ductile metal being physically and electrically connected to the anode; wherein the anode is in the form of a block formed around a portion of the length of the elongated connector.
