ELECTROCONDUCTIVE CONCRETE Russian patent published in 2018 - IPC C04B28/04 C04B111/94 C04B18/04 C04B14/06 C04B24/26 

FIELD: construction.

SUBSTANCE: invention relates to the construction and electric power industry and, in particular, to the field of creating composite materials based on natural and technogenic raw materials to produce electrically conductive concrete, it has electrical conductivity and resistivity, enough to use the material as an electrically conductive structural and heating structural material, as well as the manufacture of elements of grounding devices and antistatic floors. Electrically conductive concrete includes portland cement, sand, water and a carbon-containing component, it also uses fly ash and hyperplasticizer, with the following component ratio, by weight %: Portland cement 10–14; sand 14–19; fly ash 13–18; carbonaceous component 11.8–15.8; hyperplasticizer 0.2; water 42. In this case, thermosite sand is used as sand, and carbonaceous slime of aluminum production is used as a carbon-containing component. In addition, all dry components are subjected to mechanochemical activation in a vario-planetary mill to a specific surface of 550 m²/kg.

EFFECT: optimization of regulation of structure formation and homogenization of a multicomponent system, as well as a reduction in the cost of final products, energy and resource intensity of production.
