SUMMARY:

The construction sector has been searching for materials that have a lower impact on the built environment, so the use of wood has become attractive to be natural and renewable material. However, knowledge of physical and mechanical properties is fundamental to classify new species and indicate their use. In the northeast region of Brazil, the Caatinga biome is featured for its biodiversity being the only totally national biome. However, the physical and mechanical properties of local species are little known and investigated and therefore their application becomes limited and commonly used for energy purposes. With this, the study seeks to characterize the species mimosa tenuiflora, native of the biome and indicate potential uses in construction. Physical tests were performed to determine moisture (U), density (ρbas), apparent density (ρap), dimensional stability (ε_r, ε_i, ΔV); Mechanical compression tests parallel to fibers (FC0), parallel and perpendicular shear (FV0, FV90), parallel traction and perpendicular to fibers (ft0, ft90), parallel and perpendicular hardness (FH0, FH90), static flexion (FM0) and Flexion Elasticity Module (Moe) According to NBR 7190-3 (ABNT 2022), as well as thermal conductivity test. The indication of applications of the species was performed through the classification proposed by IPT (2013) and IPT/SUDAM (1981), using the criteria of Nahuz (1974) and Nogueira (1991). Species have physical and mechanical properties equivalent to marketed species, indicating potential use in light and external mild construction, as well as domestic floors.
