Zinc coating on carbon steels give the higher corrosion resistance in chloride containing environments andin carbonated concrete. However, hydrogen evolution accompanies the corrosion of zinc in the initial activityin fresh concrete, which can lead to the formation of a porous structure at the reinforcement -concreteinterface, which can potentially reduce the bond-strength of the reinforcement with concrete. The presentstudy examines the mechanism of the corrosion of hot-dip galvanized steel in detail, as in the model poresolutions and real concrete. Calcium ion plays an important role in the corrosion mechanism, as it preventsthe formation of passive layers on zinc at an elevated alkalinity. The corrosion rate of galvanized steeldecreases in accordance with the exposure time; however, the reason for this is not the zinc transitioninto passivity, but the consumption of the less corrosion-resistant phases of hot-dip galvanizing in the concreteenvironment. The results on the electrochemical tests have been confirmed by the bond-strength test forthe reinforcement of concrete and by evaluating the porosity of the cement adjacent to the reinforcement.
