INVETIGATION ON DURABILITY OF EUCALYPTUS WOOD (E. INTERTEXTA R. T.BAKER) BY FIELD TEST STAKES

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.
