Abstract
In this study, the damage of termites on Eucalyptus wood (Eucalyptus intertexta R.T. Baker) in both treated and untreated conditions was evaluated by IRGfWP-1290 and recommendation of ASTM Standard D-1758 methodes. The dimention of the samples were 25 x 2.5 x 2.5, 30 x 8 x 8 and 47 x 2 x 2cm that were treatd by celcure and Creosote using full cell process (Bethel) method. Retentions average of Creosote and Celcure were 53.22, 5.62 Kg/m3 respectively. The studies have shown that untreated samples of E. intertexta which have been placed in field test for 9 years, were subjected to damage about 70%, and soft rot could be seen on them. Samples treated by Celcure and Creosote which have been placed for 6 years were sound but in the 7th year the damage of the termites on the samples began to appear which was 20%. Based on this study, it can be concluded that E. intertexta wood can be classified as a moderately durable wood.
