L\u2019article fait le point sur deux \u00e9tudes r\u00e9alis\u00e9es par le Laboratoire de Technologie du Bois du DEMNA et l\u2019ULG, concernant les propri\u00e9t\u00e9s m\u00e9caniques, physiques et de durabilit\u00e9 naturelle du bois de robinier faux-acacia. Les tests de durabilit\u00e9 naturelle montrent que le duramen des grumes de robinier, \u00e9chantillonn\u00e9es en Wallonie, est constitu\u00e9 de bois globalement tr\u00e8s durable face aux champignons lignivores. C\u2019est le seul bois europ\u00e9en \u00e0 obtenir ce classement, ce qui fait de lui un bois bien adapt\u00e9 aux usages ext\u00e9rieurs, sans n\u00e9cessit\u00e9 de recours aux traitements de pr\u00e9servations, et susceptible de concurrencer les bois tropicaux traditionnellement utilis\u00e9s. En Belgique, en l\u2019absence de sylviculture adapt\u00e9e \u00e0 l\u2019essence, le bois de robinier montre des propri\u00e9t\u00e9s m\u00e9caniques mod\u00e9r\u00e9es \u00e0 hautes mais une stabilit\u00e9 dimensionnelle faible. Compar\u00e9 \u00e0 celui du ch\u00eane et du teck, il pr\u00e9sente des propri\u00e9t\u00e9s physiques et m\u00e9caniques plus \u00e9lev\u00e9es ou similaires. Les possibilit\u00e9s de valorisation semblent donc multiples : parmi les applications nobles figurent les menuiseries ext\u00e9rieures, les terrasses ou le mobilier de jardin. Son poids propre mis \u00e0 part, le robinier est adapt\u00e9 pour des usages de structure (charpente traditionnelle et menuiserie structurelle apparente). Sa nervosit\u00e9 peut \u00eatre partiellement contr\u00f4l\u00e9e par un s\u00e9chage prudent du bois jusqu\u2019au taux d\u2019humidit\u00e9 d\u2019emploi. L\u2019offre de bois de robinier ne devrait cependant pas augmenter de mani\u00e8re substantielle sur le march\u00e9 belge dans les prochaines ann\u00e9es : elle restera vraisemblablement trop basse pour des arbres de haute qualit\u00e9. Il \u00e9tait toutefois important de d\u00e9montrer que cette esp\u00e8ce m\u00e9rite amplement l\u2019int\u00e9r\u00eat qu\u2019on lui porte. [C.H.]<\/p>","protected":false},"excerpt":{"rendered":"
