Compressive Strength of Cylindrical Samples as An Indicator of Wood-Cement Compatibility
Compatibility of wood-cement mixtures proposed by early studies was expressed as an inhibitory index, which was derived from hydration temperature and/or hydration time. Sometimes this index does not reflect the […]

Compressive Strength of One- and Two-Ply Laminated Timbers
Two-ply laminated timbers were significantly stronger than single-ply lumber in both average and near-minimum compressive strength. Average stiffnesses of one- and two-ply timbers were essentially equal. Results suggest that present […]

Conidendrin in Floccosoids of Western Hemlock
Floccosoids are whitish flecks of previously unknown composition that occur rather infrequently in western hemlock (Tsuga heterophylla). Microscopic examination of the flecks has shown them to be completely included in […]

Consumer willingness to pay a price premium for standing-dead Alaska yellow-cedar
Alaska yellow-cedar has declined in Southeast Alaska over the past 100 years, resulting in half a million acres of dead or dying trees. The natural decay resistance of Alaska yellow-cedar […]

Container Planting of Douglas-Fir
Mechanized forest-tree planting in the Pacific Northwest dictates that machinery must be manually transported over the planting sites. This limits the weight and method of operation to that of growing […]

Control of Brown Stain in Eastern White Pine with Reducing Agents
Brown stain, which often develops when eastern white pine (Pinus strobus L.) is stored in hot humid conditions and then kiln-dried, was practically eliminated by dipping the freshly sawn lumber […]

Controlling Decay in Above-Water Parts of Waterfront Structures
Shallow penetration of preservative and deep checking in some Douglas-fir piles and associated members above water suggested a need for supplementary treatment. Pentachlorophenol and cresote-treated curbs with deep checks required […]

Creep response to drying of timber boards of Scots pine
Air circulation drying of boards from Scots pine (Pinus sylvestris) causes tension stress as well as mechano-sorptive creep perpendicular to the grain. In this study we demonstrate these effects by […]
