CRUDE MIXTURE FOR HIGH-STRENGTH CONCRETE Russian patent published in 2012 - IPC C04B28/04 B28B1/00 C04B111/20 

FIELD: chemistry.

SUBSTANCE: invention relates to the industry of construction materials and can be used to make concrete articles in civil and industrial construction, as well as in nanotechnology. The crude mixture for high-strength concrete, which contains portland cement, quartz-feldspar sand with fineness modulus of 2.1, granite screenings with particle size of 2.5-5 mm, a fullerene-containing modifying additive and water, the fullerene-containing modifying additive is carbon nanomaterials formed as a by-product during plasma gasification of coal, premixed and heated to temperature 50-60°C, with the following ratio of components, wt %: portland cement 25.6-26.0, quartz-feldspar sand with fineness modulus of 2.1 31.9-32.5, granite screenings with particle size of 2.5-5 mm 31.9-32.5, said carbon nanomaterials 0.01-0.0001, water 8.99-10.6.

EFFECT: high strength properties, including initial hardening period, reduced water consumption when producing concrete, use of a fullerene-containing modifying additive - carbon nanomaterials - a by-product of plasma treatment of coal in a plasma reactor.
