ORGANOMINERAL MODIFIER FOR ELECTROMAGNETIC WAVE-PROTECTIVE CONSTRUCTION MIXTURES Russian patent published in 2025 - IPC C04B28/02 C04B14/06 C04B14/10 C04B16/02 G21F1/04 

FIELD: construction.

SUBSTANCE: invention relates to the industry of construction materials, namely: to protective finishing construction materials, in particular to construction mixtures, intended for effective protection of technical equipment and a person in residential and non-residential premises from penetration of electromagnetic waves, for example, electromagnetic waves of cellular communication, and can be used in production of construction products intended for industrial and housing construction, as a decorative-protective plaster mixture for them, as well as for environmental protection. Organomineral modifier for protection against electromagnetic waves of construction mixtures includes a hydraulic binder, a silicon-containing compound, a mineral component, schungite with a degree of grinding of 200–300 m²/kg and water. Modifier additionally contains an inert solid element and non-toxic impurities, and the silicon-containing compound is contained in the composition of the mineral component, with the following content of components, wt.%: hydraulic binder: 12–20, mineral component: 10–35, inert solid element: 6–15, non-toxic impurities: 2–5, schungite with grinding degree of 200–300 m²/kg: 10–40, water is the rest.

EFFECT: increased efficiency of protection against electromagnetic waves of ultrashort radio frequency range with simplification of technology of production of proposed organomineral modifier, longer setting time, endowing it with self-compacting ability, high strength and water resistance of articles plastered with a construction mixture based on the proposed organomineral modifier.
