Determination of Eucalyptus grandis boards properties through non-destructive testing

This work evaluated the results of non-destructive testing to determine the following properties of Eucalyptus grandis boards: moisture content, basic and apparent densities, longitudinal modulus of elasticity and parallel to the fibers compressive strength. The properties of the boards were also determined by destructive testing according to the Brazilian Standard, NBR7190. The results of these tests allowed to evaluate the effectiveness of non-destructive testing and find correlations for a rapid determination of the properties of the boards. The equation found to determine the boards longitudinal moduli of elasticity from the propagation velocity of longitudinal waves and apparent density in loco was efficient and can contribute to the classification and to glulam beams optimized manufacturing.
