Abstract

It was found that the most promising method of pretreatment of plant raw materials is biological activation, or biofermentation. Biofermentation of wood aggregate was carried out in a laboratory bioreactor with the help of microorganisms contained in the substrate of animal origin - manure. Biofermentation of sawdust led to a decrease in its content of water-soluble reducing substances and, as a consequence, to an improvement of the construction-technical indicators of wood-cement composition. Pilot samples of sawdust-concrete on biologically activated aggregate were obtained and their main physical and mechanical properties were determined. The project of technological regulations of biologically activated sawdust-concrete production and a variant of using this material as an insulator of a layered panel were developed.
