- Abstract
The article focuses on the study that determines the critical chloride corrosion threshold of galvanized reinforcing bars. It states that the starting average content of critical chloride corrosion is greater than the starting time for conventional steel. Different types of metallic coatings are used to protect steel from corrosion. Among the principal metals being protected from corrosion is zinc, which is applied as a molten coating. Because zinc corrodes in alkaline and in acid environments, galvanized bars are used to passivate the zinc surface and prevent the zinc from reacting with hydroxyl ions in fresh concrete. Moreover, details on how to protect reinforcing steel from corrosion along with the conclusions made from the study are presented.
