Available in PDF, EPUB and Kindle. Book excerpt: The availability of western red cedar has decreased in recent years, and other species of wood are being considered as substitute materials for wood shakes and shingles. However, the wood of these alternative species is more susceptible to decay than is western red cedar. The objective of this study was to evaluate the fire performance of combined fire retardant and preservative treatments using different fire test methods. Several amino resin fire retardants were used in combination with several wood preservative compounds that imparted both fire retardancy and decay resistance to wood. Treated specimens underwent fire tube tests and based on the results of these tests, two fire retardants and two quaternary ammonium preservatives were selected for additional fire testing. These treated materials were subjected to a modified Schlyter test and a burning brand test. The heat release rate was also measured. Both weathered and unweathered specimens were evaluated. The unweathered and weathered treated material exhibited good fire performance.

Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume presents new scientific works of the research workers and experts from the field of Wood Science & Fire. It looks into the properties of various tree species across the continents affecting the fire-technical properties of wood and wood-based materials, its modifications, fire-retardant methods and other technological processes that have an impact on wood ignition and burning. The results of these findings have a direct impact on Building Construction and Design describing the fire safety of wooden buildings, mainly large and multi-story ones. The results of these experiments and findings may be applied, or are directly implemented into Fire Science, Hazard Control, Building Safety which makes the application of wood and wood materials in buildings possible, while maintaining strict fire regulations. One part of the contributions focuses on the symbiosis of the material and the fire-fighting technologies. Wood burning has its own specific features, therefore, the fire protection technologies need to be updated regularly. It also includes the issue of the intervention of fire-fighting and rescue teams in the fires of wooden buildings. Presentations deal with the issue of forest fires influenced by the climate changes, relief, fuel models based on the type and the age of the forest stand.

Download or read book Efficient Utilization of Red Maple Lumber in Glued laminated Timber Beams written by John J. Janowiak and published by . This book was released on 1995 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of utilizing cant-sawn hardwood lumber, which would not usually be desired for furniture manufacture, was studied for the manufacture of structural glued-laminated (glulam) timber. Two red maple beam combinations were evaluated: (1) a glulam combination designed with E-rated lumber in 25 percent of the outer laminations (top and bottom) and No. 3 grade lumber in 50 percent of the center laminations and (2) a wide-width glulam combination with laminations made from nominal 2- by 4- and 2- by 6-in. No. 2 grade lumber laid edge-to-edge having staggered end joints (termed 2 by 4/2 by 6 glulam combination). Test results of 42 red maple glulam beams showed that it was feasible to develop structural glulam timber from cant-sawn lumber. The glulam combinations made from E-rated lumber exceeded the target design bending stress of 2,400 lb/in2 and met the target modulus of elasticity (MOE) of 1.8 Ã 106 lb/in2. In addition, the 2 by 4/2 by 6 glulam combination exceeded published design stresses for vertically laminated bending strength, MOE in both the horizontally and vertically laminated orientations, and horizontal shear stress in the vertically laminated orientation. Based on the results of the 2 by 4/2 by 6 glulam combination, it was determined that edge gluing the laminations to form wide-width lumber is not required to achieve targeted strength and stiffness levels. Data analysis showed that ASTM D3737 procedures developed for softwood species accurately predict beam stiffness and provide conservative bending and horizontal shear strength estimates for red maple glulam beams. Also, it was shown that results from ASTM D143 shear-block tests could be used to accurately predict horizontal shear strength of 2 by 4 and 2 by 6 red maple glulam beams.

Download or read book Exterior Weathering Durability of Some Leach resistant Fire retardant Treatments for Wood Shingles written by Carlton A. Holmes and published by . This book was released on 1981 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a part of a continuation study on fire-retardant treatments for wood shingles and shakes, shingles were treated by systems selected from previous research, including commercially treated class C shingles, and exposed outdoors for 2, 5 and 10 years. This is a progress report after 5 years' exposure and fire testing by burning brand and modified Schylter tests. Generally acceptable results were obtained after 2 years' exposure, except for a reference pyresote treatment. After 5 years' exposure, all systems passed 80 percent or more of the burning brand tests except for the pyresote and the pyresote with light sealer coating. All systems showed weakness in the Schlyter, but in four of the eight systems flames on shingles were self-extinguishing. (Author)
Download or read book New Technologies in Protective Coatings written by Carlos Giudice and published by BoD – Books on Demand. This book was released on 2017-09-06 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials are at the center of all technological advances; it is evident in considering the spectacular progress that has been made in fields as diverse as engineering, medicine, biology, etc. Materials science and technology must develop researches allowing the generation of new methods of protection to reduce fundamentally the losses of human life as well as the economic ones. The former are impossible of quantifying, while the latter are highly significant; thus, only those derived from corrosive processes in their different forms reach, in technologically developed countries, about 4% of the Gross National Product (GNP), while those derived from fire action range from 0.5 to 1.0% of the mentioned GNP. The book, in the different chapters, displays original systems of superficial protection and of low environmental impact to minimize the losses by corrosion and the fire action.
