Abstract
The purpose of this research was to see thermal and breaking type characteristics of waste wood for construction materials using high temperature and pressure equipment. In TG/DTA graph weight of waste wood was steeply decreased at $250^{\circ}C$, it has to be treated below $250^{\circ}C$ for construction materials. In popping test the needle-leaved tree was more broken in texture than the broad-leaved tree, especially, Chamaecyparis obtusa(W-7) was the best. The optimum result was obtained at temp. $200^{\circ}C$, pressure 3MPa among the experimental condition.
