FIELD: chemistry.
SUBSTANCE: invention relates to technology of silicates, particularly to stone casting compositions, where articles made from the said material can be used in construction. The cast stone material contains the following components given in wt %: SiO2 67.3-79.4; Al2O3 6.0-10.0; CaO 6.0-10.0; MgO 1.0-2.0; Fe2O3 2.0-4.0; K2O 2.0-4.0; Cr2O3 0.5-1.0; MnO 0.5-1.0; TiO2 0.5-1.0; CoO 0.5-1.0; As2O3 0.1-0.2.
EFFECT: increased strength of cast stone material.
