HARDNESS OF LUMPY PINE WOOD, DAMAGED VARIOUS TYPES OF FIRE AFTER LONG-TERM STORAGE

Abstract

Fires have a significant impact on the wood of stands. The most valuable part of the trunk of the tree is exposed to the strongest impact. Information about the quality of wood damaged by fire is of great practical importance. The aim of the study is to establish the static end hardness of pine wood from the butt part of the trunk damaged by various types of fire. after long-term storage. It was found that after long-term storage for 10 years, the static end hardness of pine wood after storage increases more than twice, while the wood is heavily tarred, especially in the central part of the tree trunk.
