Effect of rapid redrying shortly after treatment on leachability of CCA-treated southern pine
The use of southern pine lumber treated with chromated copper arsenate (CCA) has grown tremendously in recent years. This is largely because CCA-treated wood products are clean and odorless, as […]

Effect of Species, Precompression, and Seasoning on Heartwood Preservative Treatability of Six Western Conifers
Heartwood boards of the following species were selected for treatment: coastal Douglas-fir [Pseudotsuga menziesii var. menziesii (Mirb.) Franco], interior Douglas-fir [Pseudotsuga menziesii var. glauca (Beissn.) Franco], white spruce [Picea glauca […]

Effect of surfactants on penetration and absorption of chromated copper arsenate in Douglas-fir
Five commercial cationic, anionic, and nonionic surfactants were tested for their ability to improve treatment of kiln- and air-dried Douglas-fir heartwood by chromated copper arsenate (CCA). Although some of the […]
