WHY CONNECTICUT IS USING CATHODIC PROTECTION

Article describing Connecticut's use of cathodic protection (CP) as a long-lived rehabilitation technology that will stop corrosion in reinforced concrete bridges. CP stops corrosion reinforced concrete by lowering the active corrosion potentials of the reinforcing steel. Current is supplied by an external DC power source from an outside anode embedded in the concrete, but separated from the rebar. The current flows through the concrete to the rebar. By changing the rebar into a non-corroding cathode, the electrical current neutralizes the corrosive effect of chloride ions. The protected rebar will not rust once CP is installed.
