METHOD OF OBTAINING INORGANIC HYDRAULIC BINDING SUBSTANCES Russian patent published in 2014 - IPC B09B3/00 

FIELD: chemistry.

SUBSTANCE: in accordance with claimed method material of technogenic or natural origin from group, including solid products, obtained by burning solid fuels, metallurgical slag, products of surface fires, products of burning dumps in extraction of fossil fuels, waste products of glass production, waste products of ceramics production, waste products of building bricks and concrete, thermally activated clays, low-crystalline fragmental igneous rocks, sedimentary laterite, bauxite, opalolite, allophanolite, diatomite, limestone, argillite and clays, are subjected to physical processing. Processing lies in action of, at least, one force impulse for passing mechanical energy to particles of processed material by impact of force from 50 to 3·10⁵ H with respect to 1 g of processed material for period from 1·10^-6 to 1·10^-2 and/or magnetic energy of alternating magnetic field with frequency from 150 to 15·10⁶ Hz and magnetic induction from 10^-2 to 10³ Tesla.

EFFECT: method ensures obtaining high-quality binders from different materials of both natural and technogenic origin.
