Effect of ponding, steaming and drill perforation on preservative treatment of fir wood (Abies cephallonica L.) with CCB

J. A. Kakaras, E. V. Voulgaridis

Abstract

Wood from fir (Abies cephallonica L.) in round form (length 1.20 m, diameter 14–20 cm) and in the form of beams (length 1.25 m, 5 cm×7 cm in cross section) were impregnated with 2% CCB by the full cell process after or without a pre-treatment of ponding, steaming or drill perforation. Each pre-treatment caused a significant increase of the dry salt retention and the impregnated area in fir logs and sapwood beams. Drill perforation was the most effective pre-treatment causing full impregnation of sapwood beams. Between ponding and steaming the differences were relatively small but uniform penetration was achieved only in round wood after ponding. The significantly increased penetrability, caused by the three pre-treatments under the described specific conditions, widens the uses of fir wood but it doesn’t meet the requirements of retention for the most difficult conditions in service.
