Abstract

A study was conducted on the preservative treatment of Acacia mangium poles to determine the treatment schedule for outdoor use. The poles contained 52.27% sapwood which is generally perishable by wood destroying organisms. In this study, 27 poles were treated with aqueous solution of 10% CCB by Lowry empty cell process. Three different pressures and three time periods were applied to evaluate the depth of penetration and amount of retention of the preservative chemicals. It was observed that preservative chemicals penetrated the entire sapwood portions of the poles which are the main criteria for the protection of poles. But, on the other hand, no significant increase was observed in penetration with the simultaneous increase of pressure and time period, although the retention of the preservatives was found to increase significantly. The highest retention of 22.98 kg/m3 and full penetration of sapwood was observed after 1.04 N/mm2   pressure for three hours. It is expected that the applied pressure and time period are adequate for protecting the Acacia mangium poles from wood destroying organisms in outdoor condition.
