Glue-line bonding performance of decommissioned CCA-treated wood. Part ll: Retreated with CCA.

摘要

Disposal of decommissioned chromated copper arsenate (CCA)-treated wood as landfill has become an important environmental concern. Reusing and recycling decommissioned treated wood seems to be the most practical environmental solution to the problem. In a previous report, 6-ply laminated beams made from decommissioned CCA-treated southern pine (Pinus spp.) wood utility poles and 6-ply laminated beams made from untreated virgin wood were studied to evaluate the effects of surface preparation method and cross-sectional region (high or low CCA retention) on bonding.
