Abstract
The present study aimed to evaluate the behavior of the dimensional variations of wood treated of Eucalyptus grandis W. Hill ex Maiden and Eucalyptus cloeziana F. Muelle. Samples wood were prepared with dimensions of 20 x 20 x 100 mm, with larger longitudinal, adapted the dimensions of standard COPANT 30:1-005. For each variable were use 15 samples of wood. The measurements of the radial, tangential and axial were obtained with a digital caliper 0.01 mm accuracy, as well as mass (g) of the samples on an analytical balance of 0.01 g accuracy. The values of the density of the wood species showed significant differences, as well as in the assessment of the contraction, the same behavior was identified for the swelling of the wood. The anisotropy values of contraction as well as the anisotropy of swelling, showed no statistical difference. According to the literature of Durlo and Marchiori (1992) these species can be cosiderated as normal wood.
