    Abstract. The article analyzes the features of deformation of various structures of concrete - heavy, fine-grained and light structural. It is noted that in order to construct curved deformation diagrams, it is necessary, in addition to the prismatic strength, to have two characteristics - the initial modulus of elasticity and the maximum relative compression strain. Based on past research and modern experimental results, equations have been obtained for the analytical description of the basic physical and mechanical characteristics for all classes of concrete of the listed structures. The proposed analytical equations for determining the initial modulus of elasticity and limiting relative compression deformations, as well as for constructing curved deformation diagrams for different types of concrete, have a minimum number of empirical parameters that allow describing these diagrams. It is noted that it is necessary to continue concrete research to confirm the obtained analytical dependencies. The conducted research makes it possible to expand the understanding of changes in the basic physical and mechanical characteristics and deformation diagrams for various types of concrete.
    Keywords: curved diagrams of concrete deformation, concretes of various structures, marginal relative compression deformations, modulus of elasticity, analytical equations
