METHOD OF PRODUCING BINDER Russian patent published in 2011 - IPC C04B7/153 C04B7/36 

FIELD: chemistry.

SUBSTANCE: invention relates to slag-alkaline binder and can be used in the industry of construction materials to prepare mortar and concrete for different purposes. The method of producing binder, involving grinding granulated blast-furnace slag dried to moisture content of not more than 1%, mixing with condensed microsilica with specific surface area of 15000-25000 m²/kg, adding a slag activator - calcined soda - to the binder and tempering the binder, employs grade 3 granulated blast-furnace slag, which is ground together with calcined soda, followed by mixing with microsilica and tempering the binder with water, components being in the following ratio in wt %: grade 3 granulated blast-furnace slag 90-91.5, condensed microsilica with specific surface area of 15000-25000 m²/kg 3.5-5, calcined soda in terms of dry substance 3.5-5.

EFFECT: simple technique of obtaining slag-alkaline binder with preservation of strength properties.
