ABSTRACT:
The present invention relates to a method for cathodic protection of steel reinforced concrete which comprises using an anode structure made of an array of valve metal strips activated by an electrocatalytic coating and having voids therein, supported by or inserted into insulating spacers, said strips being connected by connection means either provided with voids or without voids, or rods, bars, insulated cables. The anode structure is applied to the reinforcing steel cage during Construction before the concrete is poured. The anode structure of the present invention exhibits a remarkable mechanical resistance and has an anode surface which may be tailored in order to provide for the necessary protection current on the basis of the density of the reinforcing bars contained in the structure to be cathodically protected.
