FIELD: chemistry.
SUBSTANCE: invention relates to photocatalytic materials for use in cement. The novel photocatalytic product contains a titanium compound in crystalline phases: CaTi2O5 and/or CaTi5O11, as well as TiO2, integrated with limestone. The product is obtained by reacting limestone with a suitable titanium dioxide precursor in a basic solution, followed by thorough washing of the obtained solid product, drying and calcination at 450-700°C.
EFFECT: obtained composite material, which is used as it is or in a mixture with other components, exhibited unexpectedly high photocatalytic activity.
