ROUSSY, L. et al. Technological properties of Citharexylum montevidense (Spreng.) Mol. "espina de bañado" wood. Quebracho (Santiago del Estero) [online]. 2013, vol.21, n.2, pp.58-66. ISSN 1851-3026.

Citharexylum montevidense (Spreng.) Mol a.k.a. "Marsh Thorn" is a native species used in craft carpentry, constructions, posts and door frames. However, there are no studies that characterize technological timber qualities, which could allow wood to revalue its higher value-added products. The aim of this work was to determine the physical and mechanical features of this wood in order to identify potential new uses. Thus water content, normal density, dimensional changes, Janka hardness and static bending were determined. Density values (0.68 g.cm-3 +/-0.03) placed the wood into the semi-heavy ones. Those for shrinkage and the anisotropy coefficient (1.46%) altogether define it as a very stable one. As to static bending the wood showed average strength (MOR: 97.22 N.mm-2 +/- 14.74) and very low elasticity (MOE_ 7287.00 N.mm-2 +/- 1208.08). According to the values found for the Janka hardness, the wood ofCitharexylum montevidense (Spreng.) Mol is a semi-hard one. All the values obtained for both the physical and mechanical parameters of this woodletits good behavior be assumed as to the drying process which makes it suitable for the making of floors, openings, and furniture.
