Relationship of structure and color stonecasting materials made of mineral aggregates and technogenic raw materials

The article discusses the dependence of color stonecats materials on the characteristics of its structure. It is proved that the main influence on color provides calcium fluoride. The coloring in one or another shade of the material occurs as a result of lattice defects, which lead to a change in refractive power of the crystals in the structure of the stonecasting. It is found that the main structure-forming processes in stonecasting materials with high content of calcium fluoride are the formation of heterogeneous centers of the fluoride crystallization and liquid separation into two immiscible phases.
