Abstract: The penetration of IFKhAN-80 migrating corrosion inhibitor into cement stone was studied. It was found that the depth of steel reinforcement protection in concrete containing 3% NaCl (with respect to the binder) depends on the inhibitor dosage and application method and can be up to 15–20 cm. For practical use, the consumption rate of IFKhAN-80 will depend on the reinforcement depth but should not be lower than 0.6 L/m².

Keywords: corrosion inhibitors, migrating corrosion inhibitors, corrosion in concrete, reinforced concrete
