DURABILITY OF 6 WOOD SPECIES AGAINST MARINE BORERS IN CHABAHAR PORT COASTS (OMAN SEA)

Abstract

Samples of 6 wood species including: Oak (Quercus castaneafolia) Horn beam (Carpinus betulus), Beech (Fagus orientalis), Alder (alnus subcordata), Oriental plane (platanus orientalis) and Babul (Acasia arabica) were treated with Creosote. The dimension of samples was 200 x 75 x 20 mm. Both treated and untreated samples were installed in sea water (Chabahar port coasts) according to IRG/WP-4432 (1985). After 8, 12, 24, 33 months, the samples were inspected according to recommendation of ASTM D 2481. During this installation period, the control samples of Alder after 8 months, the samples of Oak and Hornbeam, Beech and Oriental plane after 12 months, seriously attacked. The grade of samples Babul after 12 months installation in sea water was 3.8. Treated samples with Creosote, samples of Oak 24 months and Hornbeam, after 33 months, were seriously attacked.So, treating with creosote using full cell process causes an increase in wood, durability against marine boreres approximately more than two times of untreated samples.
