Pilot Applications of Electrochemical Chloride Extraction on Concrete Bridge Decks in Virginia
A recent SHRP study confirmed that applying an electrical field between the surface of a concrete structure and the rebars (like cathodic protection, except with 50 to 500 times more current) can expel the chloride ions from salt-contaminated reinforced concrete and mitigate rebar corrosion. This new rehabilitation method was tried on two whole deck spans, as part of pilot trials in Virginia to demonstrate the practicality of this electrochemical chloride extraction (ECE) process on full-sized bridge elements and to help refine the technique. Overall, the pilot treatment of the deck was judged to be very simple to perform and more than reasonably successful.
