Abstract
Corrosion protection of reinforced concrete members with zinc-coated steel fibers was evaluated among the corrosion-protection methods against chloride-induced deterioration. Role of zinc-coated galvanized steel fibers in severe environment was confirmed as a sacrificial anode for embedded steel in an electrochemical reaction due to diffusion of chloride ion.
Modified test of ferroxyl transparent gel and accelerated corrosion test were applied to investigate the corrosion-protection behavior of embedded steel bars in the galvanized steel fiber reinforced concrete. Hydrogen evolution problem due to galvanized steel fibers in a high alkaline environment was discussed and the method of control the evolution was proposed.
