Abstract

The ways of wood thermal treatment applied in Russia and abroad and the scopes of thermo wood as a construction material are considered in the article. The technology of thermal treatment of high moisture wood with moisture content of 60% in the environment of saturated steam without preliminary drying, developed by authors, is described. The results of the research of the color scale change of oak wood depending on the processing temperature and treatment duration, and also the influence of thermal treatment on the main mechanical properties of thermally modified wood as the finishing material, in particular on the Ra and Rz roughness parameters are presented. As a result of the conducted research the improvement of final physic mechanical and esthetic characteristics of the material after the processing of wood under this technology is proven.
