This book contains the contributions from the RILEM International Symposium on Materials and Joints in Timber Structures that was held in Stuttgart, Germany from October 8 to 10, 2013. It covers recent developments in the materials and the joints used in modern timber structures. Regarding basic wooden materials, the contributions highlight the widened spectrum of products comprising cross-laminated timber, glulam and LVL from hardwoods and block glued elements. Timber concrete compounds, cement bonded wood composites and innovative light-weight constructions represent increasingly employed alternatives for floors, bridges and facades. With regard to jointing technologies, considerable advances in both mechanical connections and glued joints are presented. Self-tapping screws have created unprecedented options for reliable, strong as well as ductile joints and reinforcement technologies. Regarding adhesives, which constitute the basis of the jointing/laminating technology of modern timber products, extended options for tailor-made bonding solutions have to be stated. Apart from melamine-urea and phenolic-resorcinol adhesives, one-component-polyurethanes, emulsion isocyanate polymers and epoxies offer a wide range of possibilities. The contributions dealing with experimental and numerical investigations on static, cyclic and seismic behavior of structures clearly reveal the enhanced potential of modern timber construction for reliable and sustainable buildings and bridges of the new millennium. The book is structured in nine thematic areas, being I) Structures II) Mechanical Connections III) Glued Joints and Adhesives IV) Timber and Concrete/Cement/Polymer Composites V) Cyclic, Seismic Behavior VI) Hardwood, Modified Wood and Bamboo VII) Cross-Laminated Timber VIII) Properties and Testing of Wood IX) Glulam

The United States produces 25% of the world's wood output, and wood supports a major segment of the U.S. industrial base. Trees provide fiber, resins, oils, pulp, food, paper, pharmaceuticals, fuel, many products used in home construction, and numerous other products. The use of wood as a raw material must consider production efficiencies and natural resource conservation as well as efficient, profitable use of solid wood, its residues, and by-products. To better assess the use of wood as a raw material, the U.S. Department of Agriculture's Forest Service asked the National Research Council's Board on Agriculture to bring together experts to review the analytical techniques used to follow the life-cycle of wood productionâ€"from tree to productâ€"and assess the environmental impacts. This resulting book provides a base of current knowledge, identifying what data are lacking, where future efforts should be focused, and what is known about the methodologies used to assess environmental impacts. The book also focuses on national and international efforts to develop integrated environmental, economic, and energy accounting methologies.

Provides instructions on making paper, offers tips on everything from proper technique to troubleshooting problems with finished paper, and includes directions for dozens of projects.

This book covers the technology of the recovery of secondary fibre for its use in paper and board manufacture. The editor, who has had substantial practical experience of designing and commissioning paper recycling plants all over the world, leads a team of experts who discuss subjects including sourcing, characterisation, mechanical handling and preparation and de-inking.
