1H-perimidine (PED) and 2-hydroxy-1H-perimidine (HPED) were prepared as corrosion inhibitors for HRB400 reinforced steel in simulated concrete pore solution. The corrosion inhibition performance and adsorption mechanism were investigated via dry and wet cycle experiments, scanning electron microscopy, electrochemical impedance spectroscopy and related theoretical calculations. The results show that the inhibition efficiencies of these compounds are more than 80% for HRB400 reinforced steel in SCP at a concentration of less than 0.12 mmol/L. Moreover, HPED functions as a more effective inhibitor rather than PED due to the presence of 2-position hydroxyl-group. In addition, the inhibitor molecules spontaneously adsorb onto reinforced steel surfaces to form a protective film, and the adsorption process follows the Langmuir isothermal model.
