FIELD: building industry. SUBSTANCE: composition compound involves crushed vegetable filling agent, magnesial binding agent based on magnesium-containing inorganic mineral substances, slimes of carnallite chlorinator and water. Magnesial binding agent has waste from asbestos production as a magnesium-containing inorganic mineral substance. Wood saw-dust and/or milled chips, and/or calibrated shavings, and/or milled bark, and/or hydrolytic lignin are used as wood waste. Preliminary crushed and ground slime to large size 200 mcm, not above, is used as slimes of carnallite chlorinator of the following chemical composition, wt.-%: MgCl2; 20-40; MgO, 20-40; KCl, 20-30; chlorides and oxides of other metals, the balance. Waste with particles size 5-50 mcm, not less, are used as waste of asbestos production. The composition compound is recommended for making different building articles: wood-mineral blocks, plates, panels, pressed structural blocks, profiling articles and so on. Components are taken in the definite ratio. EFFECT: increased water absorption, strength indices, decreased coefficient of heat conductivity. 5 cl, 1 tbl
