Two-component model of the concrete composite was considered. The model is considered in two ways. Model “matrix - defects” and model of “matrix-filler”. In the model of “matrix - defects” we made the analysis of the behavior of the model depending on the number and distribution of defects in the body of the concrete prism. It is Described how to change in the number of defects in the process of loading a prismatic concrete specimen and their influence on strength and deformation properties of concrete. We obtained mathematical model of a two-component structure of concrete. We considered the changing deformation model of “matrix-filler” depending on the number and distribution of filler in the body of the concrete prism. Further models have been tested by comparison with computer models and experiments on standard prismatic specimens. It is revealed that the vertical cracks do not affect the vertical deformation of a prism.
