Book excerpt: Shallow slope failures are predominant in North Texas and pose a significant maintenance problem. The traditional slope repair and stabilization techniques become expensive in some instances with direct costs associated in maintenance and repair of landslides. A new approach for slope stabilization has been developed using Recycled Plastic Pins (RPP) to stop slope movements. The engineering properties of RPP in compression and bending strength along with environmental considerations dictate the design and repair of slopes using RPP. Two other materials have also been considered as an alternative: (1) Wood lumber and (2) Bamboo. Wood has many advantages as an engineering material. It is strong, light, and fairly simple to work with. Bamboo is typically thought of for decoration is recently becoming more popular as a structural element. Bamboo is one of the fastest growing plant in the world and readily available in developing countries like: South Asia. However, to administer their application in slope stabilization, it is necessary to have a clear understanding of their structural behavior under in situ conditions. The current study focuses on determining engineering properties of Recycled Plastic Pins (RPPs), wood lumber and bamboo and their applicability in soil slope stabilization. The RPPs, manufactured by Bedford Technology Ltd., was collected from Minnesota, the bamboo samples were collected from Benson Tropical Sea Imports and the wood lumber was collected from local stores . An extensive experimental program was developed to determine the engineering characteristics of these materials. The tests that were performed were the flexure test and the uniaxial compression as they govern to match the field load orientation. Three different strain rates were applied during the test were based on the ASTM standards and field conditions. For each strain rate, three samples from each of the respective specimen were taken. Three different environmental conditions, to match the Texas soil, were considered for the current study, 1) Acidic condition of a pH of 5.5 representing Texas red clay 2) Alkaline condition of a pH of 8.5 representating Texas black clay 3) Neutral condition of a pH of 7.0 simulating rainwater and moist conditions in field. The test results showed that wood possess highest peak strength, both in flexure and compression, but RPPs extended to accommodate more soil movments, which was upto 19% in compression at the lowest strain rate. However, the strength of wood and bamboo were decreased by 50% for wood and 65% for bamboo under different environmental conditions where the strength reduction for RPPs was only 8%. The results, both the flexure and the axial compressive tests in environement and non-environment conditions, reflect that RPPs could be utilized over wood and bamboo to stabilize slope failures in field conditions. However, for the solid condition with a pH of 7.0, all three materials can be used for slope stabilization.
Book Synopsis Sustainable Slope Stabilisation using Recycled Plastic Pins by : Sahadat Hossain
Download or read book Sustainable Slope Stabilisation using Recycled Plastic Pins written by Sahadat Hossain and published by CRC Press. This book was released on 2017-06-14 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landslides and slope failure are common in the US and rest of the world. The landslides cause significant damage to infrastructure and millions of dollars are required each year to fix the slope. A sustainable and costeffective option to stabilise the slope can have significant benefits, as it will reduce the cost of maintenance and when using recycled pins, it may help the environment at the same time. The recycled plastic pin is made from recycled plastic bottles and other plastic waste. Several demonstration projects already proved the effectiveness of RPP as an alternative option to fix slope failure, with a maximum failure depth of 7-8 ft. In this book, every detail of the slope stabilisation technique using recycled plastic pins, including the design techniques and several case studies, are included. This will help to explain the basics of this important technique and will be used as reference to design the slope stabilisation scheme using recycled plastic pins.
Book Synopsis Group Resistance of Recycled Plastic Pin in Sustainable Slope Stabilization by : Mohammad Rezaul Haque Bhuiyan
Download or read book Group Resistance of Recycled Plastic Pin in Sustainable Slope Stabilization written by Mohammad Rezaul Haque Bhuiyan and published by . This book was released on 2014 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slope failure is a common phenomenon in areas with slope constructed on high plasticity clay and shallow slope failure is predominant in North Texas. The cumulative maintenance cost of minor slides is equal or greater than major landslides. But, cost associated with post failure maintenance can be reduced significantly if an appropriate stabilization method is adopted. Thus, selection of appropriate and economically viable slope stabilization method has got great importance for the geotechnical engineers. Recently, a new approach of shallow slope stabilization technique is introduced using Recycled Plastic Pin (RPP). RPP used in shallow slope stabilization should pass beyond the slip surface to pin the sliding surface with the stiff soil. An extensive study based on the field performance of RPP installed for shallow slope stabilization was carried out by Loehr and Boders in Missouri, and Khan in Texas. In most of the cases, the horizontal displacement of RPP reinforced slope was about 3 inches both in Missouri and in Texas. The field investigation of the RPP reinforced slopes leads researchers to develop two new design protocols. They are limit resistance method by Loehr and Boders and performance based method by Khan. The limit resistance design method did not consider the effects of creep of RPP. This limitation was taken into account and a new performance based design method is proposed by Khan. But, instead of considering group resistance of RPP, only resistance of single RPP is considered in performance based method. Thus, the objective of this study is to determine the group resistance of RPP in sustainable slope stabilization. To attain the goal, number of RPP required forming an effective group at different spacing is determined. In order to fulfill the objective, an extensive study has been conducted based on numerical modeling and supported by field data. Thereby, a new design chart is proposed considering group resistance of RPP, where maximum horizontal displacement and flexural stress of RPP are taken into account. Parametric study is carried out to determine the variation of resistance between group of RPP and single RPP at different loading condition, soil strength parameters, spacing and depth of slip surface, where the horizontal displacement of single RPP and group of RPP is determined and plotted graphically. The graphical representation shows the difference of resistance between group of RPP and single RPP with increasing load, soil strength, spacing and depth of slip surface. Thus, the design charts for group of RPP at different spacing are developed considering different types of soil for different slope, where the horizontal displacement and/or flexural stress is shown with increasing applied load. Similar conditions of Interstate 70-Emma Site, as presented in the literature by Loehr and Borders is plotted on developed design chart for 4-ft deep slip surface. The interpolated horizontal displacement according to the developed design chart for RPP at 3-ft spacing is 0.51 and is in good agreement with Interstate 70-Emma Site. Finally, a multiplication factor is introduced to establish a relationship between the developed design charts to performance based method.

Book Synopsis Mechanical Properties of Bamboo by : Jules J.A. Janssen
Download or read book Mechanical Properties of Bamboo written by Jules J.A. Janssen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book I have collected many reports on the properties of bamboo. Since I started bamboo research in 1974, I have collected many publications on bamboo. However, in contacts with other researchers I became aware of the fact that several of these publications were unknown to them. Consequently their activities in research or in bamboo projects had to start at a lower level than if they had known some of these publications. Therefore, I discussed the need for a book like this with several colleagues, and I decided to start writing. In this book I present data on properties, as published by resear chers. Certainly it is not complete; e.g. the proceedings of the bamboo workshop in Cochin in November 1988 are not included; they arrived just too late to be taken into account. On the other hand, in writing this preface I realize I have forgotten my own thesis. I do apologize to any colleague whose relevant report is not taken into account as well. I like to express my feelings of respect to the board of my faculty: they allowed me to spend so much time on this book, and they gave a considerable financial support for the printing costs.

Book Synopsis Wood Properties and Processing by : Miha Humar
Download or read book Wood Properties and Processing written by Miha Humar and published by MDPI. This book was released on 2020-05-23 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal. Quality of wood is influenced by the genetic and environmental factors. One of the emerging uses of wood are building and construction applications. Modern building and construction practices would not be possible without use of wood or wood-based composites. The use of composites enables using wood of lower quality for the production of materials with engineered properties for specific target applications. Even more, the utilization of such reinforcing particles as carbon nanotubes and nanocellulose enables development of a new generation of composites with even better properties. The positive aspect of decomposability of waste wood can turn into the opposite when wood or wood-based materials are exposed to weathering, moisture oscillations, different discolorations, and degrading organisms. Protective measures are therefore unavoidable for many outdoor applications. Resistance of wood against different aging factors is always a combined effect of toxic or inhibiting ingredients on the one hand, and of structural, anatomical, or chemical ways of excluding moisture on the other.
Book Synopsis Biochar for Environmental Management by : Johannes Lehmann
Download or read book Biochar for Environmental Management written by Johannes Lehmann and published by Routledge. This book was released on 2012-05-16 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

Book Synopsis Materials and Joints in Timber Structures by : Simon Aicher
Download or read book Materials and Joints in Timber Structures written by Simon Aicher and published by Springer Science & Business Media. This book was released on 2013-09-25 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book Synopsis The Anatomy of Bamboo Culms by : Walter Liese
Download or read book The Anatomy of Bamboo Culms written by Walter Liese and published by BRILL. This book was released on 1998 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given its unrivalled position in terms of diversity, distribution and uses, coupled with the vital role it plays in the rural economies of several countries around the world, bamboo has emerged in recent years as potentially the most important non-wood forest resource to replace wood in construction and other uses. Concomitantly, the interest being shown in this invaluable natural resource since the 1980s has resulted in the accumulation of a considerable body of information through research on various aspects of bamboos, including the anatomy of the bamboo culm. There is, however, no comprehensive publication available on the anatomy of bamboo culm, with the available literature being fragmented, scattered and inadequate. This landmark monograph by renowned wood biologist, forestry expert and bamboo specialist, Professor Walter Liese, whose innovative work on the study of anatomical structure using advanced microscopy and other techniques has won him wide international acclaim, fulfils the need for a comprehensive overview of current knowledge on this subject. It is the first attempt to synthesize information from studies on this subject, many of which have been contributed by Professor Liese, spread over the past four decades. By identifying gaps in the current anatomical knowledge base of bamboo culm, it is expected to stimulate further research and to act as a prime mover for knowledge generation in the key areas of bamboo anatomy, growth and taxonomy.
