CONSTRUCTION MIX Russian patent published in 2023 - IPC C04B28/30 C04B22/12 C04B111/20 

FIELD: construction materials.

SUBSTANCE: invention relates to finishing construction mixtures designed to effectively protect technical equipment and people in residential and non-residential premises from the penetration of electromagnetic waves of cellular communications, as well as to attenuate ionizing radiation from a wide range of radionuclides. The construction mixture contains 70-80 wt.% of barite concentrate, 0.1-0.3 wt.% of calcium chloride, 0.1-0.2 wt.% of lignosulfonate, 8-10 wt.% of powder of magnesite caustic grade PMK 85. The mixture additionally contains 0.2-0.4 wt.% of nylofiber from recycled nylon and 10-19 wt.% of powdered lime and natural mineral shungite II and III modification - the rest.

EFFECT: increasing the efficiency of protection against electromagnetic waves emitted by mobile communications, as well as from ionizing radiation and gamma radiation while reducing the thickness of the plaster layer from the claimed mixture, improving adhesion, viscosity, impact resistance, crack resistance.
