Abstract

Several physical-mechanical properties of wood are evaluated from specimens in the green condition. Air-dry samples are often simply re-wetted by direct immersion in order to raise the moisture content above the fiber saturation point. It is assumed that this treatment has no effect on the properties of wood and is equivalent to the green condition. The purpose of this study was to evaluate the influence of water re-wetting processes on the dimensional properties in beech wood. Matched samples were subjected to three different full-water saturation treatments ranging from a four step mild procedure to a one-step drastic procedure. Results showed that the re-wetting process had a significant effect on swelling and shrinkage of beech wood.
