Resumo

This paper evaluates the natural durability of four wood species, so that they can be indicated or not, in situations of use in contact with the ground, the use in buildings and frame structures, or even in other applicability where there damage risks caused by biotic and abiotic factors. For this, was used four wood species from the north of the state of Mato Grosso, based on their availability, and especially in the commercial interest of woods for outdoors structures . The species used were: Tectona grandis (teca), Azadaractina indica (nim), Inga sp. (inga), Bagassa guianensis (tatajuba). Samples of the wood were exposed in field trials over 18 months and at the end was evaluated the percentage of mass loss and index decay . Among the species studied the Azadirachta indica wood showed the best results , however , the Bagassa guianensis wood showed the worst results for both the decay index as for mass loss . The density is not the main factor that adds natural durability of wood , but the content and type of extractives are contributing factors .
