PACIFIC RIM TRANSTECH CONFERENCE PROCEEDINGS. VOLUME II. MODIFIED GRAPHITE REFERENCE ELECTRODES

cesearch is reported that investigated the feasibility of developing an improved,more reproducible, reversible, and highly voltage invariant graphite reference half cell for use in controlling cathodic protection systems on prestressed concrete structures. The study compared the performance of various standard and experimental modified graphite electrodes with the best commercially available and other recently developed embeddable reference cells in salt-contaminated concrete under severe cyclic temperature conditions. It was found that selected modifications of graphite can produce a stable and reproducible reference electode which is simple to manufacture, rugged to handle and cost effective. Modified graphite has strong potential to be as good or better than the best commercial reference electrodes currently on the market.
