Description
Summary:[...]value-added examples for construction are essential. The present paper evaluated Corymbia citriodora wood to promote the effective construction use through the material characterization. [...]fourteen mechanical properties and two physical properties were estimated. Citriodora genus has excellent form, with well-shaped crown with sparse foliage, whose purpose is applied for non-wood forest products - notably, for lemon-scented essential oil - since this multipurpose tree can be grown profitably by farmers with smallholdings (CABI, 2013). [...]sixteen properties were considered to characterize the selected wood (Corymbia citriodora), whose test descriptions and requirements were prescribed by the ABNT NBR 7190 (1997) standard document to analyze: * Two physical tests at 30% and 12% moisture content: o Volumetric mass and bulk densities; * Fourteen mechanical tests at 30% and 12% moisture content: o Five modulus of rupture: * Parallel and perpendicular compression to grain, parallel and perpendicular tensile to grain, and static bending; o Four modulus of elasticity: * Parallel and perpendicular compression to grain; parallel tensile to grain, and static bending; o Other five strength resistances: * Parallel and perpendicular hardness, shear stress, cleavage, and toughness.
