METHOD OF PRODUCING WOOD-SLAG COMPOSITE Russian patent published in 2011 - IPC C04B40/00 C04B28/08 C04B18/26 C04B111/20 

FIELD: process engineering.

SUBSTANCE: invention relates to production of construction materials and may be used in production of construction materials and wood-slag composites. In compliance with proposed method, wood wastes are treated in alkaline medium at 100°C for 1-2 h, wood waste-t-liquid glass weight ratio making 1:5.6-10. Produced bulk containing water soluble lignine is mixed for, at least, 0.1 h with cementing agent consisting of blast-furnace granulated slag pre-ground to surface density of, at least, 3100 cm²/g and cement. Mix thus produced is compacted and form is removed in 8-24 hours depending upon the quality of solidification agent.

EFFECT: higher strength, reduced heat conductivity of cheap construction wood-slag composite.
