Decay resistance of cement-bonded oriented strand board

The objective of this study was to evaluate the decay resistance of cement bonded oriented strand board (OSB) against brown ( Coniophora puteana) and white rot ( Termites versicolor ) fungi. Overall, both fungi failed to attack the cement-bonded OSB. Boards made with 3.0 cement-to-wood ratio showed weight gain instead of weight loss. Therefore, it is recommended that cement-bonded OSB is technically suitable for exterior use where both moisture and favourable conditions for fungi development are present.
