PROTECTION OF STEEL REINFORCED CONCRETE ELEMENTS
First Claim
1. A method of protecting steel in a reinforced concrete element, the reinforced concrete of the element containing an electrolyte, the method comprising:
- providing at least one primary anode, wherein the at least one primary anode is a sacrificial anode;
providing at least one secondary anode, wherein the at least one secondary anode is connected to a positive terminal of at least one source of direct current, ‘
DC’
, power;
arranging the at least one primary anode and at least one secondary anode to have an ionic connection with the steel in the reinforced concrete element via the electrolyte;
connecting the at least one primary anode to the steel in the reinforced concrete element using an electron conductor;
connecting the negative terminal of the source of DC power to the steel in the reinforced concrete element using an electron conductor.

Abstract
A method of protecting steel in a reinforced concrete element is disclosed. The reinforced concrete of the element contains an electrolyte. The method involves providing a primary anode, which is a sacrificial anode, and providing a secondary anode, which is connected to a positive terminal of at least one source of direct current, ‘DC’, power. The primary anode and secondary anode are arranged to have an ionic connection with the steel in the reinforced concrete element via the electrolyte. The primary anode is connected to the steel in the reinforced concrete element using an electron conductor. The negative terminal of the source of DC power is connected to the steel in the reinforced concrete element using an electron conductor.
