ABSTRACT: Expanding the base of wood resources, adoption, and effective use of wood species depend primarily on the knowledge of the properties of the wood and the source from which the wood was obtained. The Acacia mangium wood, whose natural durability was determined to establish its practical uses, was extracted from Ada Technical Institute's compound in the Ada East District of the Greater Accra Region of Ghana. The study adopted an experimental research design. The natural durability test was done using the accelerated laboratory method based on standard. Seventy-two (72) samples were taken from the six billets (base, middle, and top). The analyses were carried out within each section, established from portions of the trees close to the pith or cascade. The resistance values indicated that the wood studied has a high resistance to rot. In this way, this wood can be used for various uses that require high resistance to interference, such as using parts in direct contact with the ground.
Keywords: serviceable life; decay resistance; Xylophagous fungus.
Durabilidade natural da madeira de Acacia mangium
RESUMO: A expansão da base de recursos madeireiros, a adoção e o uso eficaz de espécies madeireiras dependem principalmente do conhecimento das propriedades da madeira e da fonte de onde a madeira foi obtida. As madeiras de Acacia mangium Willd, cuja durabilidade natural foi determinada para estabelecer seus usos práticos, foram avaliadas pelo Instituto Técnico Ada, no Distrito Leste de Ada, da Região da Grande Accra, em Gana. O estudo adotou um desenho de pesquisa experimental. O teste de durabilidade natural foi realizado utilizando o método laboratorial acelerado baseado em norma. Setenta e duas (72) amostras foram retiradas dos seis toras (base, meio e topo). As análises foram realizadas dentro de cadaa seção, sendo estabelecidos a partir de porções das árvores próximas à medula ou a casca. Os valores de resistência indicaram que a madeira estudada alta resistência ao apodrecimento. Desta forma, essa madeira pode ser utilizadas para diversos usos que exijam uma elevada resistência a deterioração, como o uso de peças em contato direto com solo.
Palavras-chave: vida útil; resistência a deterioração; fungo xilófago.
