▎ 摘　　要

NOVELTY - Building material mixture comprises graphite as a plaster mass whose dry matter is 20-98 wt.%, 2-70 wt.% binder, 0-50 wt.% functional additives, 20-80 wt.% graphene, 0-40 wt.% magnetite, and 0-8 wt.% metallic nano particles and 0-30 wt.% metallic fibers. USE - The building material produced from building material mixture is useful as shielding material by absorption for electromagnetic radiation and/or heat energy generating or distributing material, in component such as e.g. facade panel, brick, heat storage element, ventilation element with absorption of electromagnetic radiation (all claimed). ADVANTAGE - The building material has an enormous shielding of electromagnetic radiation, and can be brought into the desired shape for processing with three dimension printer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for surface heating comprising supporting structure and a heating source and a cover layer, where the cover layer is formed from a building material mixture.
