FIELD: chemistry.
SUBSTANCE: wood-cement mixture contains sawdust with the size not coarser than 10 mm, including 85 wt % of particles with the coarseness from 1 to 5 mm inclusively, and as an inorganic filler the mixture contains wastes of mechanical stone milling in the form of marble particles with the coarseness not larger than 3 mm, including 75-95 wt % of particles with the coarseness from 1 to 2 mm, Portland cement, lime, water, fibre and additives, with the following component ratio, wt %: Portland cement 26-30; sawdust 30-34; lime 2-3; wastes of stone milling in the form of marble particles 4-5; liquid glass 3-6; aluminium sulphate 1-3; polypropylene fibres 0.05-0.2; water 25.95-26.8.
EFFECT: increase of strength, effective application of wood-sawing and stone-milling wastes and ecological safety.
