    Abstract. The article presents calculated dependences for determining the timing of initiation of reinforcement corrosion processes in saturated and unsaturated concretes with transverse cracks. A mathematical model of concrete corrosion processes developed earlier by the authors of the article, which is characterized by a spatial porosity system, is used as a theoretical basis for constructing computational dependencies. In saturated concrete, the timing of initiation is determined by the mass transfer of the acid reagent in the crack, taking into account its flow into the pore space of the concrete, where reactions with the physico-chemical transformation of substances take place. In unsaturated concrete, the process begins with the absorption of an aggressive component and the formation of an acidic reagent in the through capillaries of the concrete adjacent to the transverse crack. It is shown that the process of depassivation of the protective (alkaline) reinforcement coating is determined by the rate of mass transfer of the acid reagent in the transverse capillaries of the pore space of concrete directly adjacent to the protective coating. It has been established that in the event of a violation of the adhesion of the protective coating to concrete, an acid reagent is formed directly in the resulting gap and the speed of the process is sharply accelerated. The dependencies for unsaturated concretes take into account the influence of the reinforcement profile.
    Keywords: reinforcement corrosion, saturated and unsaturated concretes, timing of initiation of corrosion processes, transverse cracks, depassivation process, acid reagent
