BENDING PROPERTIES OF GREEN AND AIR-DRIED WOOD OF A CLONE OF Eucalyptus saligna Smith GROWN IN DIFFERENT TREE SPACING AND FERTILIZATION

ABSTRACT

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 spacing.

Key words:
bending; Eucalyptus saligna; tree spacing; fertilization
