Abstract

Samples of 3 wood species including: Beech (Fagus orientalis), Oak (Quercus castaneafolia) and Hornbeam (Carpinus betulus) were treated with creosote and celcure. The dimension of samples were 200 x 7 x 20 mm. Both treated and untreated samples were placed in sea water (Boshehr in Persian Gulf) according to IRG/WP-4432(l985). After 5, 9, 15, 24, 29 and 38 months, the samples were inspected according to recommendation of ASTM D 248. The control samples (untreated wood) of Beech, Hornbeam after 9 months, the samples of Oak after 14 months, seriously attacked. Treated samples of Beech, Oak and Hornbeam with celcure, after 14 months, were seriously attacked. Creosote, treated samples of Beech, after 29 months, Oak and Hornbeam after 38 months were seriously attacked. It can be concluded that treatment with creosote using full cell process (Bethell) increased resistance of investigated wood species against marine borers.
