Abstract

The results of scientific research aimed at determining the degree of influence of destructive factors, namely, chloride media of various concentrations and natural climatic “freeze–thaw” cycles, on concrete and ferroconcrete structures are presented. The use of the special impregnation IFKHAN-80, which is a universal corrosion inhibitor of the contact and migrating action and is intended to prevent the corrosive destruction of ferroconcrete structures operated under severe conditions and “stop” already ongoing corrosion processes during repair- and-renewal operations, is also studied. The IFKHAN-80 inhibitor reduces the negative effects of destructive factors—aggressive chemical media, namely, chlorides and temperature drops from plus to minus—freeze–thaw cycles. It is established that the destruction of concrete under the simultaneous influence of aggressive media (in this case, chlorides) and freeze–thaw cycles occurs because of the appearance of an adsorption-induced decrease in the concrete strength in a certain range of concentrations of chloride media. It is hypothesized that this range of concentrations of chloride solutions is due to their viscosity, which affects the height of the solution rise in the pores of concrete samples.
