FIELD: chemistry.
SUBSTANCE: invention relates to the industry of building materials, particularly to making articles - blocks from wood-cement compositions used mainly in farm building. The wood concrete mixture contains the following, wt %: cement 30-35; gypsum 0,5-1; modified technical lignosulphonate 0.2-0.8; bottle corks crushed into crumbs with particle size of not more than 5 mm 63.7-68.8, with water/cement ratio of 0.6-0.8.
EFFECT: low cement consumption and high frost-resistance of the wood concrete.
