The article discusses the features of the use of cement concrete with polymer composite reinforcement (PKA) in building structures. The relevance of the study is due to the need to increase the corrosion resistance and durability of reinforced concrete elements, especially in aggressive environments. The aim of the work is to study the adhesion of advanced control systems of various profiles to cement concrete under the influence of operational and technological factors. Within the framework of the study, literature sources on this topic were analyzed, as well as experimental tests of the adhesion strength of reinforcement to concrete after the influence of various factors: heat and humidity treatment, alternate freezing and thawing, water saturati on, as well as the action of alkaline solutions. The effect of the concrete class on the efficiency of interaction with the PKA was studied. Features of fracture in the contact zone are revealed and the optimal type of reinforcing profile is determined. Th e work is of interest to designers and specialists in the field of development of new building materials and technologies
