Abstract: The corrosion of reinforcement steel in concrete is a serious and widespread problem in construction. Inhibitors play an important role in protection against it. The Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences has developed an inhibitor against corrosion of reinforcement steel in concrete named IFKhAN-80. It is a non-toxic and non-flammable formulation based on raw materials available in Russia. Its functional properties have been studied in detail under laboratory and field conditions of moderate climate. IFKhAN-80 is widely used in practice, but there was no experience of its application in the tropics. The ability of IFKhAN-80 to provide contact protection of reinforcement of steel reinforcement under tropical conditions has been studied in this work by corrosion and electrochemical methods. The high efficiency of the inhibitor even for concretes with high chloride content was shown.
