Deadwood and burnt wood could be a great reserve in the construction and related industries. Although the properties and performance of healthy pine wood are known, there is practically no information on deadwood and burnt wood. Therefore, to further establish sustainable ways of using such wood, the biological durability and strength depending on operating conditions should be studied. The authors of the study determined some strength parameters on samples of pine deadwood from the Kiev region of different indicative age of desiccation (from 1 to 3 years) and on samples pine burnt wood of Zhytomyr region after grassroots fires. As a result of studies we founded hyphae of fungi on microsections of central and transitional zones of sap wood. Most hyphae were accumulated in cells of medullary rays and sap tracheids. The scientists have also shown the experimental results of some physical and mechanical properties of pine deadwood compared to healthy wood strength parameters and normative values for building constructions. These results suggest changes in micro- and macrostructure of wood, and therefore evidence of negative effects of fire and high temperatures on the strength parameters of harvested timber. Thus, we have concluded that pine deadwood and burnt wood can be used as a building material. However, in the case of manufacturing structural elements that have to bear the load on static bending, it is better to use deadwood indicative age of desiccation of one year and burnt wood from butt part of the trunk. The results of experimental studies allows some recommendations on using of pine deadwood and burnt wood and receive regulatory resistance values for the design and calculation of wooden structures.
