Sažetak
In this study, density, volumetric swelling, mass loss, volume weight, fiber saturation point and water absorption of the poplar wood (Populus usbekistanica) were investigated with the effect of heat modification (HM) and heat-modifi ed densifi cation (HMD). Poplar samples were modified with steam at 120 °C, 160 °C and 200 °C for 1 and 3 h. After heat modification, the samples were compressed in hot press at a temperature of 120 °C, press pressure of 5 MPa and press time of 30 minutes for densification. Physical properties of the samples were determined according to Turkish standards. The results showed that heat modification affected densification and increased density. Densification had a positive effect on oven dry density (D0), oven dry density after soaking (D0S), volume weight (R) and fi ber saturation point (FSP), except for volumetric swelling. Similarly, the densification process had an increasing effect on the water absorption, excluding 360 hours.
