    Abstract. The analysis of mathematical models of corrosion processes of chemical concrete is carried out in accordance with the basic provisions and requirements of the theory of mathematical modeling. It follows from the analysis that the use of a single porosity system, without taking into account all stages of the process, will not make it possible to build a general model. It is shown that its construction requires a transition to a double porosity system and a full account of all elementary stages of the corrosion process. The solution of the problem based on the general model and the calculated dependencies for predicting the technical condition of the operated structures are given. It is recommended to determine the initial data for forecasting based on the results of the analysis of concrete samples of structures. The purpose of the article is to demonstrate the possibilities of mathematical modeling during the analysis of various models, as well as during their construction and subsequent verification.
