Abstract

The corrosion protective properties of (1) No treatment, (2) Rust preventing agent and nontar epoxy paint, (3) Non tar epoxy paint, (4) Aluminum flame spraying, (5) Hot dip galvanizing, (6) Etching primer and nontar epoxy paint and (7) Uni-chrome plating of steels for retaining wall were investigated by the electrochemical measurements (the open circuit potential and tan δ) and visual observation for 15 years. In field test, the aluminum flame spraying on steel plates, the nontar epoxy paint on bolt nut and the nontar epoxy paint on anchor showed the best corrosion protective property for 15 years. The corrosion protective property of anchor was further enhanced by using jointly together with the cathodic protection.
