Book Description
For decades chromated copper arsenate (CCA) was the primary preservative for treated wood used in residential construction. However, recent label changes submitted by CCA registrants will withdraw CCA from most residential applications. This action has increased interest in arsenic free preservative systems that have been standardized by the American Wood Preservers? Association. These include acid copper chromate (ACC), alkaline copper quat (ACQ), copper azole (CBA-A and CA-B), copper citrate (CC), copper dimethyldithio-carbamate (CDDC), and copper HDO (CX-A). All of these CCA alternatives rely on copper as their primary biocide, although some have co-biocides to help prevent attack by copper-tolerant fungi. These alternative treatments have appearance and handling properties‍?similar to those of CCA and are likely to be readily accepted by consumers. Prior studies indicate that these treatments release preservative components into the environment at a rate greater than or equal to that of CCA, but because their components have lower mammalian toxicity they are less likely to cause concern in residential applications. As the treated wood industry evolves, it is probable that a wider range of types and retentions of wood preservatives will become available, with the treatment more closely tailored to a specific type of construction application.

Book Description
Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.

Book Description
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.

Book Description
Wood has played a major role throughout human history. Strong and versatile, the earliest humans used wood to make shelters, cook food, construct tools, build boats, and make weapons. Recently, scientists, politicians, and economists have renewed their interest in wood because of its unique properties, aesthetics, availability, abundance, and perha
