RAW MIX FOR ELECTRICALLY CONDUCTIVE CONCRETE Russian patent published in 2022 - IPC C04B28/04 C04B14/06 C04B111/20 C04B111/94 

FIELD: building materials.

SUBSTANCE: invention relates to the building materials industry and can be used for the manufacture of concrete products in civil, industrial and road construction, including using nanotechnology. To increase the compressive strength, specific electrical conductivity of electrically conductive concrete, the raw mix for electrically conductive concrete includes Portland cement CEM 1 32.5N, carbon nanomaterial obtained as a by-product of plasma gasification of coal, quartz-feldspar sand, granite crushed stone of 5-20 mm fraction and water, and quartz-feldspar sand contains with Mcr=2.1, while the specified carbon nanomaterial is preliminarily subjected to ultrasonic treatment in the disperser "CT-400A CT-Brand" for 10 minutes with mixing water, with the following ratio of components, wt.%: the specified Portland cement 16.79-18.89; quartz-feldspar sand with Mk = 2.1 29.39-30.64; crushed granite of fraction 5-20 mm 41.98-46.18, said carbon nanomaterial 0.08-0.1; mixing water 7.56-8.39.

EFFECT: invention increases the compressive strength, specific electrical conductivity of electrically conductive concrete.
