This book was released on 1998 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette étude est d'évaluer les possibilités de décontamination des vases de dragage polluées par des métaux lourds et de déterminer leur devenir après traitement. Les travaux portent sur des sédiments d'estuaires et de canaux prélèves sur différents sites français. Dans un premier temps, les caractérisations physiques, chimiques et minérales de ces produits ont montré des pollutions complexes et parfois très marquées. Les études de spéciation menées par une succession de séparations physiques, d'observations binoculaires et d'analyses au microscope électronique a balayage et a la microsonde, ont permis de déterminer pour chaque sédiment, les principaux porteurs de métaux (microsulfures, précipitations de carbonates, adsorptions sur des grains d'oxyde de fer, particules anthropiques,...). A l'issue de ces travaux, des essais de traitement physique et physico-chimique visant à concentrer ces porteurs sur une fraction pondérale réduite, ont été effectués. La flottation a conduit aux résultats les plus prometteurs. L'efficacité de cette technique de tri est cependant très sensible à la nature des collecteurs chimiques utilises et seuls des tests d'optimisation sont en mesure de parfaire leur choix. Par ailleurs, selon les objectifs de décontamination fixés, des séparations gravimétriques ou densimétriques complémentaires peuvent permettre d'affiner le traitement. Dans un troisième temps, le devenir des matériaux traités a été étudié sur le plan du comportement mécanique. Avec des fractions fines souvent importantes, la consolidation de ces produits est très lente. Pour prédire son évolution dans le temps, une étude expérimentale a été menée en centrifugeuse sous macrogravité. Les degrés de consolidation atteints en fin d'essai (90% après un temps équivalent de 900 jours) et les tassements mesures (70% de la hauteur initiale) ont montré la lenteur et l'importance du phénomène étudié.

Available in PDF, EPUB and Kindle. Book excerpt: What can be done about the major concerns of our Global Economy on energy, global warming, sustainable development, user-friendly processes, and green chemistry? Here is an important contribution to the mastering of these phenomena today. Written by Joseph Davidovits, the inventor and founder of geopolymer science, it is an introduction to the subject for the newcomers, students, engineers and professionals. You will find science, chemistry, formulas and very practical information (including patents' excerpts) covering: - The mineral polymer concept: silicones and geopolymers, - Macromolecular structure of natural silicates and aluminosilicates, - Scientific Tools, X-rays, FTIR, NMR, - The synthesis of mineral geopolymers, Poly(siloxonate) and polysilicate, soluble silicate, Chemistry of (Na, K)-oligo-sialates: hydrous alumino-silicate gels and zeolites, Kaolinite / Hydrosodalite-based geopolymer, Metakaolin MK-750-based geopolymer, Calcium-based geopolymer, Rock-based geopolymer, Silica-based geopolymer, Fly ash-based geopolymer, Phosphate-based geopolymer, Organic-mineral geopolymer, - Properties: physical, chemical and long-term durability, - Applications: Quality controls, Development of user-friendly systems, Castable geopolymer, industrial and decorative applications, Geopolymer / fiber composites, Foamed geopolymer, Geopolymers in ceramic processing, Manufacture of geopolymer cement, Geopolymer concrete, Geopolymers in toxic and radioactive waste management. It is a textbook, a reference book instead of being a collection of scientific papers. Each chapter is followed by a bibliography of the relevant published literature including 80 patents, 125 tables, 363 figures, 560 references, 720 authors cited, representing the most up to date contributions of the scientific community. The industrial applications of geopolymers with engineering procedures and design of processes are also covered in this book

Available in PDF, EPUB and Kindle. Book excerpt: The techniques available for the study of sediments and sedimentary rocks form the focus of this book. While field aspects are included, greater emphasis is placed on the laboratory examination of sediments. Each chapter provides introductory background material and then proceeds to a discussion of technique, the equipment, and its limitations. A concluding section includes examples of how the techniques can be used to solve sedimentological problems. Techniques in Sedimentology is an unrivalled textbook for undergraduate and postgraduate students and of great use to many other geologists.

Available in PDF, EPUB and Kindle. Book excerpt: This is a unique compilation on the use of leaching/extraction methods in different fields. The use of leaching test methods is increasing in various areas including: waste treatment and disposal; incineration of waste; soil clean-up and reuse of cleaned soil; sludge treatment. This has led to (and may increasingly lead to) the development of a large number of very similar tests in these different fields. However, these developments are taking place with no clear understanding of their mutual relationships. In view of these developments, efforts are needed to harmonize the leaching procedures that could be adapted for different matrices, as well as validate the use of existing tests in other fields. The development of a wide variety of leaching/extraction tests for different matrices is undesirable from a regulatory point of view and undesirable for industry. Clarity in testing is crucial in producer-consumer relations. This collective document will assist in improving the understanding of leaching from a variety of sources and will, where appropriate, help to bring together the approaches used in different technical fields and in different countries.

Available in PDF, EPUB and Kindle. Book excerpt: L'ETUDE DE LA QUALITE DU LOT ET DU RIOU MORT MONTRE QUE LES MESURES PRISES POUR LIMITER LA POLLUTION METALLIQUE ONT REDUIT DE MANIERE SIGNIFICATIVE LES CONCENTRATIONS DE ZN ET CD EN SOLUTION. PENDANT NOTRE ETUDE, LES CONCENTRATIONS MOYENNES DE ZN ET CD EN SOLUTION DANS LE RIOU MORT ONT ETE RESPECTIVEMENT DE 2,8 PPM ET 87.10#-#3 PPM. LES CONCENTRATIONS SONT FORTEMENT DEPENDANTES DU DEBIT DU RUISSEAU. LA PRECIPITATION DE ZNCO3 ET CDCO3 PEUT AUSSI PARFOIS CONTROLER LA SOLUBILITE DES METAUX. DANS LE LOT EN AVAL DE LA CONFLUENCE AVEC LE RIOU MORT, LA DILUTION PARTICIPE A LA BAISSE DES TENEURS, MAIS D'AUTRES PHENOMENES DOIVENT AUSSI INTERVENIR (ADSORPTION ?). LA CONCENTRATION MOYENNE DE ZN A ETE DE 25.10#-#3 PPM TANDIS QUE LE CD ETAIT FREQUEMMENT INFERIEUR A NOTRE LIMITE DE DETECTION (0,5 10#-#3 PPM). DES VARIATIONS PONCTUELLES ET SAISONNIERES DE LA PHYSICO-CHIMIE DE L'EAU ONT ETE MISES EN EVIDENCE. DANS LES SEDIMENTS RECENTS LES CONCENTRATIONS MOYENNES SONT ENCORE ELEVEES: 100 ET 20 PPM DE CD, 4200 ET 1020 DE ZN ET, 330 ET 140 DE PB, RESPECTIVEMENT DANS LE RIOU MORT ET A CAPDENAC-GARE. IL EXISTE VRAISEMBLABLEMENT PLUSIEURS TYPES D'ASSOCIATIONS ENTRE LES METAUX LOURDS ET DIVERS COMPOSANTS DES SEDIMENTS (MATIERE ORGANIQUE, OXYDES DE FER, CARBONATES). DES VARIATIONS SAISONNIERES ET SYNCHRONES DES CONCENTRATIONS EN ZN, CD ET PB DANS LES SEDIMENTS DU LOT A CAPDENAC-GARE ONT ETE MISES EN EVIDENCE. LE TRANSPORT DES METAUX LOURDS SE FAIT PRINCIPALEMENT SOUS FORME PARTICULAIRE. L'ETUDE DES RELATIONS ENTRE LE LOT ET LA NAPPE ALLUVIALE DE CAPDENAC-GARE MONTRE QU'UNE FRACTION IMPORTANTE DE L'EAU POMPEE DANS LE CHAMP CAPTANT PEUT PROVENIR DE LA RIVIERE VIA LES BERGES. DANS LES BERGES ET L'AQUIFERE, LA MINERALISATION DE LA MATIERE ORGANIQUE PAR LES MICRO-ORGANISMES PEUT ENTRAINER LOCALEMENT UNE REDUCTION DES CONDITIONS D'OXYDOREDUCTION PROVOQUANT UNE MISE EN SOLUTION DU MANGANESE NATURELLEMENT PRESENT DANS LES SEDIMENTS. PRES DES BERGES, CES CONDITIONS ASSEZ REDUCTRICES, APPARAISSENT LORSQUE LA TEMPERATURE DE L'EAU EST SUPERIEURE A 10C. ELLES NE SEMBLENT PAS AVOIR PROVOQUE LA REMOBILISATION DES METAUX LOURDS PRESENTS DANS LES SEDIMENTS DU LOT ET LEUR TRANSPORT JUSQU'AUX OUVRAGES SITUES A PROXIMITE DE LA RIVIERE. LES EXPERIENCES D'ACIDIFICATION EN LABORATOIRE CONFIRMENT QUE DANS LE RIOU MORT, LES CARBONATES CONTROLENT LA SOLUBILISATION DU ZN ET CD LORSQUE LE PH EST SUPERIEUR A 5,5 (ZN) ET 6,5 (CD). DANS LE LOT, ET POUR DES PH FAIBLES DANS LE RIOU MORT, LES METAUX LOURDS SEMBLENT CONTROLES PAR L'ADSORPTION
