rebar is most frequently the result of the chloride- induced. breakdown of the passive :film formed in the high alkaline condition of concrete. In the present investigation the corrosion behavior ofcoated rebar in sec has been studied. Rebar were coated with: 1) epoxy 2) Zinc- Rich 3) Zinc-Aluminum – Rich. To simulate marine substructure environment, macro cell corrosion has been created via chloride concentration gradient. Test condition and methods of macro cell current measurement described in ASTM G 109-92 were followed.. Other nondestructive electrochemical tests have also been performed on the specimen.
