The efficacy of wood preservatives were determined in a soil-bed test. Samples of alder wood sapwood (Alnus glutinosa subsp. barbata) (5x10x100 mm) were treated with Solutions of CCA (1 % and 2 %), ACQ-1900 (2 % and 3 %), ACQ-2200 (1 % and 2 %), Tanalith E 3491 (2 % and 2.8 %), Wolmanit CX-8 (% 1 and 2 %). Modulus of Elasticity, modulus of rupture, mass loss and decay rate according to AWPA E7 were determined for specimens exposed in soil bed.
Results from this study showed that modulus of elasticity can be used to prediction of early stage of wood decay since it is non destructive method.
