A comparison between the effects of ACC & CFK on the durability of beech, hornbeam and cottonwood by using Dipping & Bethel methods in the North of Iran
1997 - IRG/WP 97-40089
From the economical point of view, increasing the lumber durability by the application of preservative treatments is very important. In this study, samples were randomly selected from Fagus orientalis Lipsky., Carpinus betulus L. and Populus deltoides Bartr. in two forms (Board & Squared cross-section) and have been treated with ACC & CFK by using Dipping & Bethel methods. The matched treated and untreated samples have been exposed to outdoor conditions for 3 years in the North of Iran. The decrease of the weight of samples has been considered as the comparison factor. The results have indicated that there are no significant differences (at 95% confidence limits) among the species, but there is a significant difference between the treated & untreated samples. The experiments have also shown that ACC treatment (using Dipping method) has been less effective on Squared cross-section samples than other treatments. Utilization of CFK is recommended fo hornbeam & cottonwood and application of ACC is recommended for beech.
