Abstract

The evaluation of wood durability enables the definition of reliable parameters to predict service-life of wood-based products. This study aimed to evaluate the wood deterioration of four fast-growing eucalyptus species (Eucalyptus botryoides, Corymbia citriodora, Eucalyptus paniculata e Eucalyptus tereticornis) exposed to three field tests (outdoor, flooded site and forest canopy) during 540 days. The physical properties measured were: mass loss, density and moisture content. Furthermore, we determined changes in wood color by CIEL*a*b* method and performed a visual analysis by CEN grades. Among the four wood eucalypts, Eucalyptus tereticornis presented the highest decay resistance. The flooded site presented the best conditions for the proliferation of xylophagous agents. Mature wood was least susceptible to deterioration than juvenile wood.
