Abstract: Teor de umidade e densidade básica da madeira de nove espécies comerciais amazônicasLívia Helena Carrera SILVEIRA¹, Alba Valéria REZENDE¹, Ailton Teixeira do VALE¹ RESUMO Este trabalho teve como objetivo agrupar espécies com características de teor de umidade e densidade básica da madeira semelhantes para compor cargas mistas de espécies para secagem em câmaras industriais de secagem da madeira. Foram amostradas nove espécies em floresta de terra firme na Amazônia Central com três repetições por espécie. Em to… Show more

“…The mean value obtained from the apparent density of 0.680 g/cm³ classifies Erisma uncinatum Warm wood as a heavy wood [14], with the same classification as Minquartia guianensis, Lecythis poiteaui, Mezilaurus itauba, Manilkara huberi and Brosimum rubescens [10]. However, Erisma uncinatum Warm wood is lighter, since the density of the other ranging from 0.835-0.904 g/cm³.…”

“…As the density is a basic physical property, its values allows the determination of an adequate estimation of the wood properties [2,10]. The estimatimation of some properties of strength and stiffness by density via mathematical models (regression models) enables to the engineer a better pre-sizing of the structure.…”

“…The value obtained from fc0 (55 MPa) for Calycophyllum multiflorum wood is very close to that obtained for Amescla-Aroeira (59.03 MPa) from the research developed by Logsdon et al (2005), being Amescla-Aroeira a wood used in structures but that is in extinction, evidencing the possibility of the use of Calycophyllum multiflorum wood in structures of medium to large dimensions. The mean value obtained from the apparent density [0.770 g/cm³] of Calycophyllum multiflorum classifies it as a heavy wood (Melo et al, 1992), being the same classification as Minquartia guianensis, Lecythis poiteaui, Mezilaurus itauba, Manilkara huberi and Brosimum rubescens (Silveira et al, 2013), however, is still lighter than the species mentioned above, whose densities range from 0.835 to 0.904 g/cm³. It is denser than medium apparent density woods, such as Liquidambar sp.…”

“…Since the density is a basic physical property, its values allows determining an adequate estimate of some wood properties (Almeida et al, 2014;Silveira et al, 2013). The estimation of strength and stiffness properties by density via mathematical models (regression models) allows the engineer, known the density of the wood species chosen and determined experimentally, to estimate the values of strength and stiffness to be used in the pre-designing of the structure.…”

“…It is noteworthy that such properties are directly influenced by moisture content (physical property) and vary according to species. Furthermore, the addition of the same due to exposure of the wood in contact with water or humid environments, is responsible for reducing the resistance properties of wood [1][2][3][4][5][6][7].…”
