THE INFLUENCE OF HOT DIPPED GALVANIZATION OVER THE CORROSION OF THE REINFORCEMENT STEEL OF THE CONCRETES

The corrosion is a complex phenomenon that depends on the composition and structure of the metallic material, the nature and composition of the corrosive environment, as well as on the conditions where the reactions take place. The presence of the electrolytes in the aggressive environment influences the corrosion speed. In the category of the electrolytes with a strong corrosive action is also included the sodium chloride - NaCl. In the hereby paper there are presented aspects related to the OB 3 7 steel corrosion (carbon steel encountered as material of reinforcement of the reinforced concrete elements) in sodium chloride solutions, the influence of the electrolyte concentration, the variation in time of the corrosive processes and the pH influence of the corrosive environment.
