Full textThe study of the behavior ofmaterials constitutive ofa coyer ofstorage ofwaste must be realized. The principal material is the clay of Aptien. It is altered, humidified and compacted to guarantee the sealing of the work. The traditional step consists in characterizing the behavior ofmaterials in laboratory and on the site of the work. Tests conventional (simple compression, triaxial compression tests) and nonconventional (direct, indirect traction) in laboratory were carried out to determine the important parameters. An extension of the results was made on rising and deflection tests on site. A mechanical improvement of clay behavior by fibres was aimed. Interpretations of the results were made to optimize the placement of materials. However the experiments in laboratory are not sufficient and difficult to lead. A numerical modeling by the MED was considered. Simulations were gauged on tests used for materials of the ground. The difficulty lies in the modeling of the clay which can be subjected simultaneously to traction and compression (deflection test). The clay microstructure was not reproduced but to model by one assembles contact segments. Severallaws of contact were used. The influence of the microscopic parameters of the model on the macroscopic behavior of the samples was studied. An extension ofthese results to the modeling ofa test ofrising ofbig size and in situ was carried out. It is a first answer to the real behavior of the argillaceous coyer of the site

Full textThe study of the feasibility of a deep geological disposal facility conducted by ANDRA - the French national radioactive waste management agency -, requires the knowledge of water status and water content in clays. Thanks to an original lab-built device coupling vibrational spectroscopies and water adsorption isotherms, adsorbed water and clay's structure are described quantitatively and qualitatively. A multidisciplinary approach allows the description of hydration mechanisms and water molecules network in the interlamellar space of synthetic saponites. The effects of density and nature of interfoliar cations and the influence of temperature on hydration are presented. Using mechanisms and important parameters established on saponites, hydration of bentonite MX80 is carried out. In order to describe and quantify simultaneously two different water states, a simple but relevant method of spectra analysis was developed

Full textNowadays, geologic nuclear waste storage is envisionned according to a multi-layer model which implies clays. The latter exhibit retention capacities and low permeability to water ; that is why they are considered as a good candidate for engineered barriers to radioactive waste disposal. The present work here aims at studying transport phenomena which involve water molecules in three samples of synthetic clays (two of them exhibiting a « Pake doublet ») by means of Nuclear Magnetic Resonance (NMR). The first chapter describes structural proporties of clays and presents the state-of-art of NMR and other experimental techniques used for such systems. The second chapter deals with the interpretation and the simulation of each conventionnal proton spectrum. These simulations allow us to evidence and to characterize a chemical exchange phenomenon. The third chapter is dedicated to original nutation experiments performed under low radiofrequency field in the case of broad NMR signal. It is shown that this type of NMR experiment can yield the number and the proportion of each species contributing to the whole signal. These results are exploited in the fourth chapter for processing relaxation and diffusion experiments. Finally, the diffusion coefficients obtained by NMR are divided by a factor 4 with respect to pure water while relaxation rates are two orders of magnitude greater

Full textCompacted clays are used in many applications, including geotechnical and environmental geotechnical applications, due to their low permeability and retention properties. However, once in place, these materials could be exposed to thermal and/or water variations in the long and very long term. The main objective of this work is to experimentally quantify the impact of these variations on the compressibility of a compacted clay, and in particular its creep. With this objective, oedometric cells with controlled temperatures between 5 and 70°C were developed. Two types of oedometers with suction controlled by osmotic and saline methods were used in a suction range of 0 to 20.8 MPa, and at a constant temperature of 20°C. These devices were used to study creep up to a vertical stress of 3600 kPa. The study focused on the behavior of a moderately swelling compacted clay. The obtained results first showed that the yield stress σ’p decreases as the temperature increases. The creep coefficient Cαe increases with temperature, this effect being particularly marked at higher stresses. A linear relationship between the creep coefficient Cαe and the incremental compression index C*c was observed within the stress range considered and the ratio (Cαe /C*c) is temperature dependent. Then, two complementary experimental approaches (creep tests by steps or at controlled strain rate) highlighted the dependence of creep characteristics on soil suction. In addition, the yield stress σ’p increases with increasing strain rate έv and suction. In contrast, the compression index Cc and the creep coefficient Cαe vary in a non-monotonic manner with a maximum value under suction of 3.5 and 2 MPa, respectively. The evolution of these parameters appears to be strongly related to the internal structure of the soil. Analysis of the variation of σ’p with έv and Cαe with Cc showed that the relationship Δlog σ’p /Δlog έv =Cαe/Cc is also valid for the studied compacted clayey soil in saturated and unsaturated states. In conclusion, the results of this work allowed information to be gathered for better understanding the compressibility and creep behavior of compacted clayey soils as a function of temperature and suction

Full textUnderstanding the mechanical characteristics of clay-based materials is critical in earth sciences and a variety of industrial applications. Clay, as the main component in these heterogeneous materials, plays a significant role in the mechanical behavior of such materials. Through the Molecular Dynamics (MD) simulation, the present thesis is devoted to investigating the mechanical behaviors of swelling clay minerals at atomic scale by putting the emphasis on the influences of water content, loading path, crystal structure anisotropy and mean stress. The thesis is composed of three parts. The first part mainly focuses on the mechanical properties of dry Na-montmorillonite (MMT) which is subjected to triaxial compression and extension loading with different constant mean stresses. A series of Molecular Dynamics (MD) simulations have been carried out respectively in the parallel and perpendicular directions to crystal layers. The effects of loading path, mean stress and anisotropy on mechanical properties of dry MMT at atomic scale are fully studied and discussed. The second part investigates the influences of water content on the physical and mechanical properties under triaxial compression with a constant mean stress. At first, the swelling property is characterized by the relationship between inter-layer distance and the extent of hydration. Secondly, the stress-strain relationships are obtained for different water contents. In addition, the micro-structure and inter-layer connection of the dry, one-, two-, three-layer hydrated MMT systems between initial and failure states have been analyzed in-depth. At last, the key mechanisms triggering their failure at the atomic scale are identified and analyzed. The third part is devoted to describing the creep deformation of MMT. Through the MD simulation, three representative creep stages have been clearly characterized. The effects of applied stress level, deviatoric stress, the temperature and microstructure orientation on the time dependent responses of MMT have been investigated

Full textThis study is devoted to the electical and dielectric properties of consolidated clays. A better understanding of the conduction and polarisation phenomena in clays is necessary to better interpret in situ measurements in term of water saturation and texture. An experimental study was carried out on synthetic clay samples (kaolinite and smectite) compacted with various water contents, porosities and mineralogical compositions, on a large frequency range, using three laboratory setups. The electrical properties of natural argillites (from Andra) were theninvestigated. We found that the response of the synthetic samples is mainly controlled by water content on the whole frequency range ; two polarization phenomena were observed, which were related to the Maxwell-Wagner polarization and the electrical double layer polarization around the clay particles. The electrical response of argillites is more complex ; it is controlled by water content but also by the microstructure of the rocks, the electrical and dielectric anisotropies are high ; anisotropy was also measured for the synthetic clays.

L'abaissement à 10 µg/L de la limite de qualité pour l'arsenic dans l'eau de consommation pose la question de l'efficacité des
traitements existants. De nouvelles techniques plus performantes d'élimination de l'arsenic sont donc de plus en plus
nécessaires. L'objectif de ce travail est de développer de nouvelles méthodes d'analyses de l'arsenic, fiables et utilisables sur le
terrain, ainsi que des méthodes simples d'élimination de l'arsenic, de mise en œuvre facile et applicables à de petites unités de
traitement comme celles rencontrées en zones à habitat dispersé (débit < 10 m3/h).
L'adsorption de As(III) et As(V), méthode répondant aux critères précédemment définis, a été étudiée. Tout d'abord des
supports classiques ont été considérés : des (oxy)hydroxydes de fer; puis des supports innovants : des argiles pontées dérivées
d'une montmorillonite. Celle-ci a été modifiée par différents polycations (fer, titane et aluminium) de façon à créer des sites
favorables à l'adsorption. L'adsorption a été réalisée selon différentes conditions, et dans des milieux plus ou moins complexes.
Il s'avère que les (oxy)hydroxydes de fer fixent plus d'arsenic que les argiles pontées, tant sous la forme As(III) que As(V).
Néanmoins, l'étude de la désorption a montré que l'argile pontée au fer était le seul support régénérable quasiment à 100%.
Connaissant les différences de comportement selon la nature des espèces de l'arsenic inorganique As(III) et As(V), l'oxydation
de As(III) par différents oxydants usuels a été l'objet d'une partie de l'étude. Les oxydants testés sont H2O2, NaOCl, FeCl3,
KMnO4 et MnO2(s), couramment employés dans les traitements. De façon à quantifier la capacité oxydante de ces réactifs, une
méthode colorimétrique a été développée. Celle-ci, facilement transposable sur le terrain, peut être appliquée aux eaux peu
chargées en phosphate avec une limite de quantification de 20 µg As/L. Il s'avère que les oxydants les plus facilement
utilisables dans une unité de potabilisation sont KMnO4 et FeCl3. A la suite de cette étude, un support à base d'une résine de
polystyrène recouverte d'oxyde de manganèse a été synthétisé. Ce solide combine des propriétés d'oxydation et d'adsorption
simultanées. Les capacités d'adsorption de ce solide vis-à-vis de As(V) et de As(III) sont remarquables et supérieures à une
majorité des adsorbants étudiés récemment.
La dernière partie a consisté en l'étude de la faisabilité des procédés mis au point sur un milieu plus proche des conditions
naturelles. Pour cela, une eau artificielle représentative des eaux de type granitique, habituellement concernées par la pollution
arséniée, a été préparée à partir de la compilation des compositions d'eaux souterraines destinées à la production d'eau potable.
Ainsi, les concentrations en ions majeurs communes à ces eaux ont pu être déterminées. Cette eau artificielle a ensuite été
utilisée après dopage en As(III) et As(V) dans diverses expériences d'oxydation et d'adsorption de façon à appréhender les
mécanismes mis en jeu dans le milieu naturel. Il apparaît que les ions majeurs ont peu d'influence sur ces procédés, démontrant
leur applicabilité au sein d'une filière de traitement.

Full textThe aim of this PhD work is to contribute to the understanding of the relationship between the acoustic and physical properties of natural satured sediments. In the framework of applied research in the environmental management of dams, and more specifically for monitoring sediment stocks in dam reservoirs, this study focuses on clay sediments, and their acoustic properties for frequencies within the kHz-range. We adopt an original experimental approach to measure the acoustic properties of the sediments through which compressional wave propagate. We designed an ad hoc laboratory laboratory set-up (waveguide) to measure the acoustic properties of viscous fluid media, in order to meet the specific requirements of the study. First, the measurements are analysed in a direct manner, in the time domain. Second, the identification problem is addressed and solved in the frequency domain, with the help of appropriate inverse methods (minimization of a cost function and perturbation method). The laboratory measurements, carried out on clay, highlight the influence of particle concentration on sound speed. We were also able to observe and characterize the visco-elastic behaviour of the clay, in particular the sound speed dispersion (the higher the frequency, the greater the speed) and attenuation
