This book was released on 1993 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA NECESSITE DE PRENDRE EN CONSIDERATION LE PHENOMENE DE LA NON-SATURATION, DONT LA CARACTERISTIQUE PRINCIPALE EST LE DEVELOPPEMENT DE PRESSION NEGATIVE OU SUCCION, SE FAIT ACTUELLEMENT PRINCIPALEMENT RESSENTIR. DANS CE CADRE, NOUS PRESENTONS DES RESULTATS EXPERIMENTAUX RELATIFS A DES ESSAIS DE DETERMINATION DE LA CONDUCTIVITE HYDRAULIQUE ET DES ESSAIS TRIAXIAUX SUR UN LIMON NON SATURE. DEUX METHODES DE MESURE DE LA CONDUCTIVITE HYDRAULIQUE SONT EXPOSEES. LA PREMIERE, BASEE SUR LE SUIVI DU DEBIT SORTANT LORS DE L'APPLICATION D'UNE PRESSION D'AIR (SUCCION), PERMET D'ETUDIER LE COUPLAGE ENTRE LES VARIATIONS VOLUMETRIQUES DE L'ECHANTILLON ET CELLES DU VOLUME D'EAU DRAINEE. AFIN DE MESURER TRES PRECISEMENT CES PETITES VARIATIONS, QUI, BIEN EVIDEMMENT, NECESSITENT UN LONG TEMPS D'EXPERIENCE, UN SYSTEME DE MESURE DE HAUTE PRECISION A ETE UTILISE. LA SECONDE METHODE REPOSE SUR LE PRINCIPE DES PROFILS INSTANTANES ET PERMET DE COUVRIR UNE LARGE GAMME DE SUCCION. POUR CHAQUE METHODE, LES ESSAIS SERONT REALISES EN DRAINAGE ET EN HUMIDIFICATION. LES ESSAIS TRIAXIAUX, SUR LES ECHANTILLONS NON SATURES, ONT ETE REALISES DANS UNE CELLULE TRIAXIALE A SUCCION IMPOSEE

Download or read book Bio aggregate based Building Materials written by Sofiane Amziane and published by John Wiley & Sons. This book was released on 2013-02-05 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using plant material as raw materials for construction is a relatively recent and original topic of research. This book presents an overview of the current knowledge on the material properties and environmental impact of construction materials made from plant particles, which are renewable, recyclable and easily available. It focuses on particles and as well on fibers issued from hemp plant, as well as discussing hemp concretes. The book begins by setting the environmental, economic and social context of agro-concretes, before discussing the nature of plant-based aggregates and binders. The formulation, implementation and mechanical behavior of such building materials are the subject of the following chapters. The focus is then put upon the hygrothermal behavior and acoustical properties of hempcrete, followed by the use of plant-based concretes in structures. The book concludes with the study of life-cycle analysis (LCA) of the environmental characteristics of a banked hempcrete wall on a wooden skeleton. Contents 1.

Download or read book Unsaturated Soil Mechanics in Engineering Practice written by Delwyn G. Fredlund and published by John Wiley & Sons. This book was released on 2012-07-30 with total page 946 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive guide to unsaturated soil— from the world's experts on the subject This book builds upon and substantially updates Fredlund and Rahardjo's publication, Soil Mechanics for Unsaturated Soils, the current standard in the field of unsaturated soils. It provides readers with more thorough coverage of the state of the art of unsaturated soil behavior and better reflects the manner in which practical unsaturated soil engineering problems are solved. Retaining the fundamental physics of unsaturated soil behavior presented in the earlier book, this new publication places greater emphasis on the importance of the "soil-water characteristic curve" in solving practical engineering problems, as well as the quantification of thermal and moisture boundary conditions based on the use of weather data. Topics covered include: Theory to Practice of Unsaturated Soil Mechanics Nature and Phase Properties of Unsaturated Soil State Variables for Unsaturated Soils Measurement and Estimation of State Variables Soil-Water Characteristic Curves for Unsaturated Soils Ground Surface Moisture Flux Boundary Conditions Theory of Water Flow through Unsaturated Soils Solving Saturated/Unsaturated Water Flow Problems Air Flow through Unsaturated Soils Heat Flow Analysis for Unsaturated Soils Shear Strength of Unsaturated Soils Shear Strength Applications in Plastic and Limit Equilibrium Stress-Deformation Analysis for Unsaturated Soils Solving Stress-Deformation Problems with Unsaturated Soils Compressibility and Pore Pressure Parameters Consolidation and Swelling Processes in Unsaturated Soils Unsaturated Soil Mechanics in Engineering Practice is essential reading for geotechnical engineers, civil engineers, and undergraduate- and graduate-level civil engineering students with a focus on soil mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: As the author states in his Preface, this book is written at a time when scientific and lay communities recognize that knowledge of environmental chemistry is fundamental in understanding and predicting the fate of pollutants in soils and waters, and in making sound decisions about remediation of contaminated soils. Environmental Soil Chemistry presents the fundamental concepts of soil science and applies them to environmentally significant reactions in soil. Clearly and concisely written for undergraduate and beginning graduate students of soil science, the book is likewise accessible to all students and professionals of environmental engineering and science. Chapters cover background information useful to students new to the discipline, including the chemistry of inorganic and organic soil components, soilacidity and salinity, and ion exchange and redox phenomena. However, discussion also extends to sorption/desorption, oxidation-reduction of metals and organic chemicals, rates of pollutant reactions as well as technologies for remediating contaminated soils. Supplementary reading lists, sample problems, and extensive tables and figures make this textbook accessible to readers. Provides students with both sound contemporary training in the basics of soil chemistry and applications to real-world environmental concerns Timely and comprehensive discussion of important concepts including: Sorption/desorption, Oxidation-reduction of metals and organics, Effects of acidic deposition and salinity on contaminant reactions Boxed sections focus on sample problems and explanations of key terms and parameters Extensive tables on elemental composition of soils, rocks and sediments, pesticide classes, inorganic minerals, and methods of decontaminating soils Clearly written for all students and professionals in environmental science and environmental engineering as well as soil science

Both these insects cause severe damage to cassava in Africa and South America, respectively. This book reviews these interactions (plant selection by the insects, nutritional requirements
