Abstract: In this work, the inhibited effect of organic carboxylamine (ZX) and triethylenetetramine (TETA) in simulated concrete pore solution and concrete was studied through linear polarization (LPR), potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and concrete-salt water dry-wet cycle test. The results show that the organic carboxylamine corrosion inhibitor can obviously inhibit the reinforced corrosion in simulated concrete pore solution. As the dosage of inhibitor increases, the inhibited effect is better. Because the N and O atoms in organic carboxylamine corrosion inhibitor adsorb on the metal surface, this organic inhibitor not only can coordinate with Fe atoms to form strongly bonds, but also prevent the charge transfer in the metal corrosion process. When the addition is 0.30wt%, the inhibition efficiency of ZX is more than 90% and the inhibition efficiency of triethylenetetramine is 63.74%. The inhibited effect of ZX is obviously better than TETA at low dosage. Further, the reinforced corrosion area in the blank group reaches more than 30%, while the corrosion area is 15.54% with 0.60wt%TETA group and 0.80% with the ZX. Carboxylamine is better inhibition effect in concrete. It can be concluded that adding organic carboxylamine corrosion inhibitor into concrete can improve the concrete structure durability and prolong the service life.
