  • Reference electrode for monitoring steel-in-concrete potentials
    Patent number: 5964992
    Abstract: A graphite reference electrode for use in the cathodic protection of steel embedded in concrete has been produced with a stable catalyzed structure that when equilibrated with air or oxygen and an electrolyte reaches a reproducible and reversible redox potential. This stable device is produced by exposure to hydrogen peroxide, impregnating with a metal oxide followed by a coating treatment. The embedded catalyzed graphite reference electrodes can be used in impressed cathodic protection systems or monitoring the corrosion condition of embedded steel to provide an early warning of impending damage.
