According to GOST 19222-84, the dependence of the physical-mechanical characteristics of sawdust concrete on the specific gravity of wet sawdust of coniferous species and ash-slag mixture in the composition was studied. A one-factor experiment was carried out in the laboratory of the Department of Reproduction and Processing of Forest Resources, Federal State Budgetary Educational Institution of Higher Education “Bratsk State University” in order to justify the specific share of wet sawdust in the composition of sawdust concrete, to determine the necessary number of observations and repetitions of the experiment. As a variable factor, the proportion of wet sawdust of coniferous species in the composition is assumed. The proportion varies from 17% to 37% in increments of 5%. The applicability of wet sawdust of coniferous species for the production of heat-insulating building materials is established. Samples of building materials were made; the necessary laboratory tests were carried out. The range of variation of sawdust content in the composition for sawdust concrete is determined (from 17 to 32%).
