###### ABSTRACT

The laws of mass transfer, common to the whole variety of natural phenomena, make it possible to rationally design building structures in accordance with the modes of operation, optimal selection of material, and assessment of the state of structures. The study of mass transfer processes occurring during corrosion destruction is a problem of current interest, from a scientific and practical point of view. On the basis of a mathematical model, an engineering calculation method has been synthesized, and a computer program has been developed for determining the completion time of the initial stage of corrosion of cement concrete of type II.
