Sawdust concrete obtained with the use of wood waste from the Republic of Buryatia and ultrafine additives

The article presents the results of obtaining sawdust concrete using wood waste and ultrafine additives. The characteristics of raw materials for obtaining sawdust concrete have been determined. It is shown that the introduction of nanosilica leads to an increase in the compressive strength of cement stone and sawdust concrete. X-ray phase analysis of cement stone showed a change in the intensity of the peaks of portlandite and calcium hydrosilicates. The kinetics of strength gain during compression of sawdust concrete with the introduction of nanosilica has been determined.
