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

The methods recommended by GOST 31383-2008 are used to study influence of migrating
inhibitors of corrosion IFKHAN-80, -80F, Sika Ferrogard 903 and MCI 2020 on corrosive-
electrochemical behavior of reinforcing steel in concrete. It is established that IFKHAN
inhibitors on functional properties are highly competitive with Sika Ferrogard 903. MCI
2020 in the conditions of experience the ability to protection of a steel has not shown.
