FIELD: chemistry.
SUBSTANCE: invention relates to the industry of building materials, particularly to production of articles (boards, blocks) from wood-cement compositions used mainly in low-height construction. The wood concrete mixture contains the following, wt %: cement 40 - 45, lime 2-3, foaming agent PB-2000 0.3-0.35, liquid glass 2-3, sheet glass ground to specific surface area 4000 cm2/g 7-10, hogged chips crushed to particle size of not more than 5 mm - the balance, wherein the water/cement ratio is equal to 1.1-1.3.
EFFECT: lower cement consumption and higher strength.
