Review article

The article presents an analysis of works on alkaline corrosion of cement concrete. It is shown that of particular interest are works that analyze the effect of concrete cracks, which appeared during operation, on the intensity of such corrosion. A model of changes in volume deformations of concrete samples has been developed, which is based on the phenomenon of technogenic metasomatosis involving chemical and physical-chemical processes leading to the transformation of the parameters of the structure and composition of the material under the influence of the external environment. An analysis of the model is carried out and the consequences are formulated, the fixation of which in experimental studies will make it possible to identify the course of technogenic metasomatosis in concrete.
