FIELD: chemistry.
SUBSTANCE: invention relates to construction materials, particularly dry construction mixtures for making gas gypsum and can be used to produce heat insulation, structural-heat insulation and acoustic materials. The dry construction mixture for making gas gypsum contains the following in pts.wt: gypsum binder 100, aluminium powder 0.1-0.2, sodium fluoride or aluminium fluoride or calcium fluoride 0.1-1, calcium oxide or calcium hydroxide 0.1-10, tartaric acid or boric acid 0.1-2.
EFFECT: production of gas gypsum with improved operational properties.
