Abstract
The purpose of this research is to evaluate the effectiveness of nitrate as a corrosion inhibitor in mortar containing chloride. In the experiment, test specimens of mortar to which chloride and nitrite had been added, were subjected to accelerated corrosion by means of repeated drying and wetting on condition of high temperature. This study concerns the assessment of the inhibition effect of nitrite-based corrosion inhibitor using a polarization method and its influence on the chloride transport, compressive strength and setting time of concrete. From the results of the experiments, it was confirmed that the lithium, calcium nitrite corrosion inhibitor and new corrosion inhibitor over dosage 0.6 (NO2-/Cl-) molar ratio is very effective in protecting reinforcement from corrosion in mortar in which chloride ions have contained.
