METHOD FOR PRODUCTION OF COMPOSITE CARBONIZED PRODUCTS Russian patent published in 2018 - IPC C04B28/18 C04B2/00 B28B3/26 C04B40/02 C04B18/12 

FIELD: construction.

SUBSTANCE: method for production of composite carbonized products includes mixing of killed calcium or dolomite lime and carbonate filler in the form of waste from extraction and processing of limestones fractions up to 5 mm with to produce moulding mass, the carbonization of the products with carbon dioxide. In addition, the cutting of the products is carried out. And the moulding mass is prepared by extrusion method. Provide the extrusion moulding of the products from the moulding mass under the pressure of 55-75 kg⋅s/cm². At the same time the wastes from stone sawing of the shelly limestones or nummulite limestones, or crushing and processing wastes of calcareous rock for break stone, or crushing and processing wastes from volcanic rocks for break stone are used as the carbonate filler.

EFFECT: product strength increase.
