Abstract: Bamboo presents a low natural resistance to decay, which constitutes one of the major limitations to its use. This study aims to evaluate pyroligneous acid effect against fungal bamboo deterioration through an accelerated laboratory decay with testing reference (without treatment) and treated specimens with the product diluted in boiling water at (0%, 5%, 10%, 20% and 30%) in different immersion times (15, 45, 90, and 180 minutes). Bamboo splits were evaluated after 6 and 16 weeks of exposure. Visual inspections and non-destructive tests (mass loss and ultrasound at 6 and 16 weeks) and bending (after 16 weeks) were applied to the bamboo strips. Results of the non-destructive tests did not allow to detect the effect of the factors (soil type, immersion time and solution concentration) on these properties. Only a superficial attack was observed by visual inspection, which did not denote mass loss. Immersion time shows a positive effect on modulus of elasticity (Em0) and on modulus of rupture (MOR). Moduli of elasticity and rupture were not influenced by soil type (sterile or natural), or by the concentration of the solution, respectively.
