This book was released on 1998 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: With relative humidity and temperature data from the National Oceanic and Atmospheric Administration, the average equilibrium moisture content for each month of the year was calculated for 262 locations in the United States and 122 locations outside the United States. As an aid for storage of kiln-dried lumber, a graph is presented for determining the reduction in equilibrium moisture content that results from heating air in an enclosed storage space above the temperature of the outside air.

Available in PDF, EPUB and Kindle. Book excerpt: Until recently, much of the development of building materials has predominantly focused on producing cheaper, stronger and more durable construction materials. More recently attention has been given to the environmental issues in manufacturing, using, disposing and recycling of construction materials. Sustainability of construction materials brings together a wealth of recent research on the subject.The first part of the book gives a comprehensive and detailed analysis of the sustainability of the following building materials: aggregates; timber, wood and bamboo; vegetable fibres; masonry; cement, concrete and cement replacement materials; metals and alloys; glass; and engineered wood products. A final group of chapters cover the use of waste tyre rubber in civil engineering works, the durability of sustainable construction materials and nanotechnologies for sustainable construction.With its distinguished editor and international team of contributors, Sustainability of construction materials is a standard reference for anyone involved in the construction and civil engineering industries with an interest in the highly important topic of sustainability. Provides a comprehensive and detailed analysis of the sustainability of a variety of construction materials ranging from wood and bamboo to cement and concrete Assesses the durability of sustainable construction materials including the utilisation of waste tyre rubber and vegetable fibres Collates a wealth of recent research including relevant case studies as well as an investigation into future trends
Download or read book Evaluating Shrinkage of Wood Propellers in a High temperature Environment written by Richard D. Bergman and published by . This book was released on 2008 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Minimizing wood shrinkage is a priority for many wood products in use, particularly engineered products manufactured to close tolerances, such as wood propellers for unmanned surveillance aircraft used in military operations. Those currently in service in the Middle East are experiencing performance problems as a consequence of wood shrinking during long-term storage at low equilibrium moisture content conditions prior to installation. To evaluate the extent of shrinkage, seven sugar maple (Acer saccharum) veneer propellers were dried from 11% to 3% moisture content in a controlled environment of 150°F (65°C) for 3 days. Two of these wood propellers were encased in polyethylene bags. Results showed 5 to 20 times more shrinkage for the thickness of the propeller hub and the hub face perpendicular to the propeller blades (across the grain), respectively, compared with the hub face parallel to the blades (along the grain). Two hubs, coated with aluminum oxide paint, showed dimensional changes similar to those observed for uncoated hubs. For the two wood propellers encased in polyethylene bags, moisture loss was slowed during the course of the experiment by roughly 46%. Wrapping the wood propellers prior to shipping would slow moisture desorption, thereby minimizing shrinkage during short-term storage. Processing the propellers at a lower equilibrium moisture content would minimize shrinkage during long-term storage.

This book was released on 2012-12-13 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT-- OVERSTOCK SALE -- Significantly reduced list price Wood preservatives are generally grouped into two categories: preservatives used for in-place field (remedial)treatment and preservatives used for pressure treatments.A limitation of in-place treatments is that they cannot beforced deeply into the wood under pressure. However, theycan be applied into the center of large wooden membersvia treatment holes. These preservatives may be availableas liquids, rods, or pastes. Pressure-treated wood has muchdeeper and more uniform preservative penetration thanwood treated with other methods. The type of pressuretreated wood is often dependent on the requirements of thespecific application. To guide selection of pressure-treatedwood, the American Wood Protection Association developedUse Category System standards. Other preservative characteristics, such as color, odor, and surface oiliness may alsobe relevant. Guidelines for selection and application of fieldtreatments and for selection and specification of pressure-treated wood are provided in this document.

This book was released on 2009 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Log moisture content has an important impact on many aspects of log home construction, including log processing, transportation costs, and dimensional stability in use. Air-drying times for house logs from freshly harvested trees can depend on numerous factors including initial moisture content, log diameter, bark condition, and environmental conditions during drying. In this study, we evaluated air-drying properties of young-growth Sitka spruce (Picea sitchensis (Bong.) Carr) and of western hemlock (Tsuga heterophylla (Raf.) Sarg.) from logs harvested in southeast Alaska. For each species, we considered inside storage in a warehouse vs. outside storage, as well as debarked logs vs. logs with bark remaining, resulting in four experimental treatments. We considered moisture losses after 8 and 12 months of air drying. There was considerable moisture loss for Sitka spruce logs, and much of the drying occurred during the first 8 months. Fastest drying rates for both species were for peeled logs with inside storage. Western hemlock logs showed higher moisture content and greater moisture content variation (vs. Sitka spruce), and in most cases would require additional drying beyond the 12-month study period to produce satisfactory house logs. Results of this study are significant because they can help entrepreneurs determine appropriate levels of capital investment (e.g., land, covered storage, debarking equipment), as well as whether to dry and process logs in southeast Alaska vs. some other location. This study found that a leading option for local producers would be to peel Sitka spruce logs, then air dry indoors for between 8 and 12 months. Another effective strategy would be to peel western hemlock logs, then air dry indoors for 12 months.
