Abstract

This paper has the purpose of contributing to the corrosion prevention and control of the reinforcement with the use of corrosion inhibitors. The inhibitors studied were sodium nitrite and other two based on amine, compared to a reference concrete without inhibitor. To evaluate the preventive efficiency, the specimens containing inhibitors were submitted to accelerated attacks by chlorides, through of the alternate wet and dry cycles in a 1% NaCl solution. To estimate this efficiency, electrochemistry measurements were carried out after each exposition change. As repair method, the specimens were made with the addition of 0,8% of chlorides, in cement mass proportion. After the confirmation of active corrosion, the inhibitors were applied on the specimens surface. To verify the efficiency, electrochemistry measurements were also performed. The trends showed that the studied inhibitors have different capacity to prevent and control the corrosion process.
