The dependence of the physical and mechanical characteristics of arbolite products on the specific content of rapeseed particles and mineral binder in the original composition was established. The results were obtained, which ensure the establishment of patterns of influence of technological parameters on the properties of wood composite material made using rapeseed waste. The main factors affecting the strength of the material are substantiated, in particular, the content of water-soluble substances in the lignocellulosic filler, the adhesion of the filler to the cement binder, the strength of the filler, the activity of cement and its consumption per 1 m3 of this material. It was found that the increased content of mineral substances in rapeseed stalks has a positive effect on adhesion with mineral binders. It was found that the presence of highly porous internal parenchyma tissue in rapeseed stalks makes it possible to use it with a content of more than 35% in the chip mass for the production of heat-insulating wood composite materials based on a mineral binder. It has been experimentally proven that wood composite materials made by conventional technology, with the addition of wood particles to the composite materials up to 35% of rapeseed particles, have mechanical indicators that meet the requirements of the state standard DSTU EN 312-2:2003. Methods of manufacturing composite materials based on mineral binder using rapeseed waste are proposed, which make it possible to expand the raw material base for the production of these materials thanks to the involvement of biomass of agricultural production – rapeseed raw material, reduce the cost of arbolite and, accordingly, save valuable wood raw materials.
