This paper proposes the problem of the complexity and consistency of a qualitative description and the reliability of a quantitative assessment of the characteristics of the structure of building composites. The results of an experimental assessment of the statistical error in identifying the structure of building composites (by the example of silicate microconcrete) by the methods of X-ray phase and differential thermal analysis are presented in comparison with the relative error of mechanical tests of the material. It is shown that under the condition of setting technological factors under control, the statistical variability of the composition and structure of the material does not exceed 5-7%, and the physical and mechanical properties are at the level of 10%.
