Nanostructures based on carbon and silicon dioxide to improve the properties of building and structural materials

The article presents hardware and technological solutions for obtaining a product containing silicon dioxide from nanodispersed dust of gas cleaning of silicon production, intended to improve the properties of building and structural materials. To obtain nanostructures of carbon and silicon dioxide of the required quality, allowing to improve the properties of building and structural materials, a complex resource-saving technology of their high-tech production was developed. The necessary characteristics of nanodispersed modifying additives have been determined. A technological scheme has been developed; technological operations of thermal vortex enrichment are described. The material balance of thermal vortex enrichment is given.
