Evaluation of various chemical treatments to prevent the abiotic deterioration of southern pine surfaces through outdoor screening trials

Creator:: Schauwecker, Christoph F.
Abstract:: Rapid discoloration and checking of wooden surfaces when exposed outdoors has caused wood to fall out of favor as an outdoor building material, especially in applications where appearance is important. The surface appearance of wood products exposed outdoors can be improved through the application of film forming coatings or by...

Moisture effects on properties of wood-composite assemblies

Creator:: King, David
Abstract:: Engineered wood composites are used in many structural applications and are intended for dry use. However, these materials may encounter significant amounts of wetting while in service, which can lead to structural failures. This study combined aspects of wood science, mechanics, structural engineering, and mycology to assess changes in material...

Essential oil treatment of VTC wood

Creator:: Scouse, Adam A.
Abstract:: Western juniper and cinnamon essential oils were combined with ethanol at 2.5, 5, and 10% concentrations by weight and applied to hybrid poplar (Populus trichocarpa x P. deltoids) veneers by vacuum soaking to produce a naturally durable wood veneer with increased mechanical properties for use in structural composites. Half of...

Copper compounds for durable composites : effects on material properties

Creator:: Vidrine, Cheney L.
Abstract:: The effects of incorporation of selected biocides on physical and mechanical properties of aspen strandboard were assessed using five copper-based preservatives or zinc borate at three retention levels. Tebuconazole or 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (DCOI) were added as co-biocides to selective copper-based treatments. Mold box tests showed that only panels treated with DCOI...

Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

Utilization of ground peanut husk as an alternative fiber material for particleboard

Creator:: Newton, Jacob A.
Abstract:: This research examined the potential for using peanut husk as a fiber alternative to wood in the production of melamine-formaldehyde (MF) particleboard. MF resin was used to produce panels with one, three, six, nine or 12 percent resin contents. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB)...

The Effect of Sill Height on Decay in Air-Seasoning Crossties

Creator:: Rogers, Leon R.
Abstract:: The sustainable use of wood for rail ties requires chemical treatment to increase service life and maintain structural integrity. Treatment can only be applied after lengthy air-seasoning to reduce moisture content in wood, but seasoning leaves ties exposed to attack by decay fungi for up to a year. One factor...

Potential for Using Boron Compounds with Differing Water Solubilities in Pastes for Remedial Treatment of Utility Poles

Creator:: Uysal, Selim
Abstract:: Boron and boron compounds have been long used for pressure treatment, dip-diffusion, and remedial treatments of wood because of their proven efficacy against fungi and insects. These materials are especially attractive because their high water solubility promotes deeper penetration into wood. Other useful properties of boron include its neutral pH,...

Development of a test method for assessing water repellency and derived physical stability of preservative systems for railroad ties

Creator:: Beck, H. Greeley
Abstract:: Resistance to moisture uptake is an important attribute of some wood preservatives and can help reduce moisture cycling that leads to the development of deep checks. While the potential for preservative treatments to help improve wood/moisture interactions is acknowledged, there are no tests that specifically evaluate this performance parameter. Checking...
