Propriedades de flexão estática da madeira úmida e a 12% de umidade de um clone de eucalyptus saligna smith sob o efeito do espaçamento e da adubação

The bending properties of a Eucalyptus saligna Smith clone were studied. Thirty trees, with age of approximately ten years, coming from Klabin-Riocell forests were used in the tests. The specimens, manufactured following ASTM D143-94 (1995), were tested in two series: after conditioning in standard room (200C and 65% relative humidity) or after water soaking. The results indicated values 1,296 and 1,4 times larger for air-dried when compared to moist wood, for bending stiffness and strength, respectively. Wood density, modulus of rupture and elasticity increased with fertilization and tree spaci ng.
