Protection of Reinforcements from Chloride Attack by the Use of Galvanized Steel and Calcium Nitrite
Galvanized steel and corrosion inhibitors added to concrete are considered methods to protect reinforcement from corrosion. In present paper the simultaneous and separated use of both methods are considered. Concrete specimens have been made for the study. For depassivation the spray salt chamber was used. The results show that if No2 is used the resistance of galvanized steel to chloride attack is improved. Bare steel embedded in concrete with NO2 resists well chloride attack.
