Abstract

This study aimed to evaluate the effect of long term waterlogging in some physical and mechanical properties of Corymbia citriodora and Eucalyptus grandis wood. Three trees of each specie were obtained in experimental homogeneous plantations aged 50 years. The samples were obtained dividing each tree into three parts of 1 m. Each part was subdivided into four samples with 25 cm height and denominated small logs. One part was used as control sample and the others were immersed into water and taken out at different times: 4, 8 and 12 months. The wood samples were tested for static bending mechanical test, specific gravity (SG) at 12% and contact angle. The results showed that the modulus of rupture of the two wood species decreased until 8 months of waterlogging and there was an increase of homogeneity and specific gravity of the two kinds of wood.
