Study on Durability of Oak Wood by Field test stakes

With the aim of measuring the durability of Oak wood (Quercus castaneafolia), 2×2×45cm wood samples were prepared. The treatments were included natural wood and impregnated with Celcure. Wood samples with 20 replication installed in 2 zones in north of Iran included Chamestan and Shalman in Mazanderan and Gilan provinces respectively. Evaluation of samples was done qualitatively based on ASTM D-1758-01. According to the results of periodically evaluation, Oak wood is “perishable”. All of the Celcure impregnated samples after 60 months were sound. Stating on longtime result of wood preservative effect needs more investigation.
