CATHODIC PROTECTIVE CURRENT DENSITIES OF COASTAL STEEL STRUCTURES IN SEVERAL POLLUTED SEA WATER ZONES

Mean protective current densities of cathodically protected steel structures, including wharfs and piers, were measured at 17 harbors in industrial districts of Japan. Dissolved oxygen, and sulfide- and hydrogen-ion concentrations were chosen as variables representing sea water pollution. A definition of "pollution index" was given as a sum of these concentrations, each multiplied by a constant. Corrosion rates and mean protective current densities were evaluated from the pollution indices in the following four zones of marine pollution: (1) Repurified zone; (2) Zone of mild pollution; (3) Zone of pollution; and (4) Zone of high pollution.
