    Abstract. The article presents calculated dependences for predicting the timing of the formation of a critical (threshold) concentration of an acid reagent on the surface of the reinforcement under conditions of chloride and carbonate corrosion. Two variants of the formation of a critical concentration on the surface of the reinforcement are considered. In the first case, the mass transfer of an acid reagent in the pore space of concrete is considered, in the second - in a transverse crack crossing the protective layer of reinforcement. The calculated dependences are based on a mathematical model of the processes of chloride and carbonate corrosion of concrete developed by the authors. This model takes into account the spatial porosity system and the distribution of calcium hydroxide particles in transverse capillaries. To describe them, a structural element is allocated in concrete. The presence of reinforcement is taken into account by a new boundary condition, according to which the surface of the reinforcement is impermeable during mass transfer of an acid reagent. The purpose of this article is to establish the basic patterns of the corrosion process at the boundary with the reinforcement, leading to damage to the passivating coating on it and the formation of corrosion sources.
