WOOD-CONCRETE MIXTURE Russian patent published in 2016 - IPC C04B18/26 

FIELD: construction.

SUBSTANCE: invention relates to industry of construction materials and can be used in manufacturing materials based on wood filler. Wood-concrete mixture contains wood filler, mineral binder and water, wherein wood filler for wood-concrete mixture is secondary wood filler with particle size 0.315-20 mm, obtained during processing of particleboards, and binder is non-cement silica-ash composition consisting of fly ash with high calcium ratio, microsilica, which is waste from production of crystalline silicon, and saline mineralized waste-water, which are wastes from non-ferrous metallurgy, obtained as a result of neutralization of industrial wastes of metallurgical production, being associated product of refining of non-ferrous and precious metals with lime milk, at the following component ratio, wt%: said wood filler 20-24; fly ash with high calcium ratio 37-43; said microsilica 2.3-2.8; said saline mineralized waste-water 0.9-1.0; rest is water.

EFFECT: technical result is creation of inexpensive construction material with provision of strength and density, reduced power consumption in production of wood-concrete and utilization of wastes due to usage of secondary wood filler and non-cement binder, obtained from industrial wastes.
