FIELD: construction.
SUBSTANCE: wood cement slab comprises a rough relief on the surface, has multiple sheet layers, every of which contains cement, a material containing silicon dioxide, wood fibres and wood flour, besides, cement and the material containing silicon dioxide are contained at the mass ratio from 3:7 to 7:3, the wood flour is coated with calcium, and its particle size varies from 0.3 to 1.5 mm, and quantity of wood fibres and wood flour does not exceed 9 wt % relative to the total content of hard substances. Also the method is described to manufacture a wood cement slab.
EFFECT: slab may be made if press pressure is not higher than 10 MPa, and demonstrates superb constructiveness of a surface, bending strength and long-term service life.
