摘要：
The attempt was made to find a correlation between the density of thermally modified pinewood treated at various temperatures and times and its compressive strength and modulus. The highest correlation coefficients were obtained for the temperature of 160 degrees C and short modification times. Under these conditions, an increase of strength properties occurred. The highest size changes of the analysed samples were observed at higher temperatures, accompanied by a marked weight loss and decrease in both compressive strength and modulus of elasticity. The data obtained allow predicting modified wood strength on the base of its density. Changes in the density and strength of modified wood are caused by a fundamental change in the structural composition of the wood.
