| dc.description | The aim of this study was to evaluate the potential application of some chemical
compounds as corrosion inhibitors for a carbon steel (CA-50) used as reinforcement of
concrete in artificial pore solution. The tested compounds were sodium nitrite (1.5% in
mass), hexamethylenetetramine (1.5% in mass) and benzotriazole (10-2 M). The techniques
used in this investigation were electrochemical impedance spectroscopy (EIS),
potentiodynamic polarization tests and open circuit potential measurements as a function of
time. Each compound tested was added to a solution whose composition simulates that of
the liquid inside the pores of concretes. To this solution was also added sodium chloride
(3.5% in mass) to simulate the corrosive effects of marine atmospheres. The corrosion
resistance of the carbon steel (CA-50) was evaluated in the solutions with and without the
additives. A beneficial effect (corrosion resistance increase) was found for all types of
inhibitors tested, but sodium nitrite and benzotriazole showed a significant inhibiting effect. | |
