1981-6-1  The application of four sacrificial zinc anode cathodic protection systems to a reinforced concrete highway bridge deck is described. Two system designs were found to be the most promising in terms of polarized potentials and protective current densities achieved during the 3 year monitoring program. One design uses commercially available zinc ribbon anodes spaced at 5 in (127 mm)

CATHODIC PROTECTION FOR REINFORCED CONCRETE

In this study a variety of impressed-current and sacrificial-anode approaches to cathodic protection in the laboratory and in prototype testing was examined. A sacrifical-anode design using zinc ribbons in combination with an essentially nonconductive asphaltic concrete overlay was determined to hold promise if problems associated with low driving voltage and expansion of anode corrosion ...
