| The objective of this work was to evaluate hygroscopicity modification of Eucalyptus dunnii, E. saligna and Corymbia maculata wood due to termites attack. Using samples measuring 20 x 20 x 150 mm³ (tangential x radial x longitudinal) the equilibrium moisture content (MCE), linear contractions of the tangential and radial planes (βT e βR), contraction anisotropy (CAβ), water absorption (AA) and water absorption rate (TAA) of healthy and deteriorated wood by Nasutitermes termites were evaluated. It was verified that the termite attack caused increase in TUE and reduction in βT. However, βR and CAβ presented different behaviors, varying among the different species. AA and TAA presented higher water absorption intensity in the first hours of immersion, being... |

| The knowledge about the technological properties of the wood enables the achievement of tools that assist in the adequate use of this material. Therefore, the aim of this study was accomplish the technological characterization of Eucalyptus benthamii wood for potential uses. For this, it was used six trees of the forestry plantation implanted in the Guatambu city, Santa Catarina State, Brazil. For the physical characterization of the wood, discs were obtained at three different positions of the trunk of each tree, determining the basic density and retractibility. The test pieces to the mechanical tests of parallel compression to the fibers, dynamic bending, static bending and Janka hardness were obtained from discs removed of the logs. The average basic... |
