    EN: Abstract When carrying out repair work on the restoration of reinforced concrete structures of transport facilities, the technical requirements for repair compounds are determined by a number of factors, namely: adhesion and chemical compatibility of materials, compatibility with linear expansion coefficient, technology repair, cost of material, etc. Very often, the combined action of the materials of the old and the new concrete is not considered at all, although the durability and quality of the repair work depends on it. Estimation of factors that influence on structural compatibility of old and new concrete is performed in this paper. Attempt of review and choice of tools of finite element analysis with the help of which may be modeled combined action of multiplayer concrete designs is also performed.
