Full textThis thesis addresses two questions related to the general topic of aeolian dune migration. The first aspect concerns the processes of erosion and deposition during an avalanche of grains. By means of an experimental device allowing to drop a column of grains without initial speed on a granular slope, we have quantified the relative importance of erosion and deposition phenomena. In particular we have measured the neutral angle which defines the critical slope at which these two processes balance each other. The second aspect focuses on the internal structure of aeolian dunes. With our co-workers from the University of Cornell (USA), we have developed capacitance probes allowing to determine the volume fraction and water content of a granular pile from measurements of electric permittivity. Thanks to these probes, we were able to characterize the stratigraphy of dunes in Mauritania. Our results showed that the internal structure of the dunes presents a marked stratification with an alternation of loose and compact layers

Full textVery large quantities of construction and demolition wastes and especially concrete wastes are produced yearly. At the same time, high amounts of natural aggregates are needed for construction industry. Up to now, only a small fraction of these concrete wastes is re-used as recycled concrete aggregates (RCA) for the manufacture of concrete. RCA are composed of an intimate mix between aggregates and hardened cement paste (HCP). Hardened cement paste is much more porous than the natural aggregates and the properties and proportions of HCP largely influence the properties of RCA. As a consequence, the fine fraction of RCA (FRCA), essentially composed of mortar and cement paste, possesses a large water demand which makes it harder to recycle into concrete.The objective of this research is to better understand the role played by HCP on the properties of RCA in relation with the improvement of the characterization methods of these materials and their reuse in the manufacture of mortar or concrete. Firstly, an experimental method based on salicylic acid dissolution allowing to determine HCP content of FRCA is developed. FRCA properties are then studied as a function of hardened cement paste content, particle sizes and properties/composition of the original concrete. From the obtained relationship between water absorption and cement paste content, the water absorption coefficient of the smaller fraction (0/0.63mm) can be estimated whereas it is difficult to measure. Secondly, different industrial RCA are characterized which allows us to expand the preceding conclusions to “real RCA”, meanwhile, the influence of carbonation on the properties of FRCA is also carried out. Finally, the influence of the saturation state of FRCA on the properties of fresh and hardened mortars and on their microstructure is explored. The recycled mortars with dry FRCA have better compressive strength than that with saturated FRCA, which is confirmed by the study of ITZ properties. The mechanical properties of mortars with different RCA content and replacement fraction are determined. The finer fraction of RCA has a worse influence on the mechanical properties of RAC than the coarser fraction

Full textBenthic macrofauna plays a major role in the trophic and iogeochemical functioning of coastal sediments. This dissertation aimed to assess the role of benthic macrofauna in metabolic changes (oxygen and ammonium) at the sediment-water interface in two major macrobenthic communities of Eastern English Channel: the fine sand Abra alba and the sandy gravels community with patches of Ophiothrix fragilis. All along the study, oxygen and ammonium fluxes presented a spatial and seasonal variability mainly related to the particle size of the sediments, to seasonal temperature increase and to changes in the quantity/quality of the organic matter.Irrigation fluxes obtained (without effect of temperature and organic matter) are correlated with macrofaunal characteristics and three functioning hypothesis may apply within these two communities: diversity-stability, pop-rivet and idiosyncrasy. Isotope analysis performed showed that benthic organisms assimilate the same type of organic matter and that the trophic functioning is similar in these two communities. The variability of irrigation fluxes could be attributed to the presence of a few numerically dominant species or adequately represented in the two communities. It is therefore difficult to establish a single law in the functioning of the macrobenthic compartment for the whole Channel area. In terms of carbon budget, the respiration of these two macrobenthic communities and medium-fine sands (Ophelia borealis) is approximately 40% of pelagic primary production

Full textBuilding materials are porous materials, and therefore very sensitive to water. Due to variable hermodynamical ambient conditions, processes of energy and mass transfers between the ambient air and the material occur. These exchanges lead to important modification of their thermal properties and their durability. For instance, measurements of the thermal conductivity of Hemp Lime Concrete, placed in climatic chamber in which the relative humidity is 75%, show a variation of 30%. This PhD Thesis deals with the case of three porous buildin materials: Aerated Autoclaved Concrete (AAC), Hemp Lime Concrete (HLC) and Vertically Perforated Brick (VPB). The hygrothermal behaviour of these materials is studied with the experimental set-up called cell of exchange. This cell consists of test walls which are place between a climatic box and the laboratory. The scope of this experimental work is to create gradients of temperature and of relative humidity through the sample. So, the study aims to measure and characterise heat and mass flows in these materials. Ln a second part, simulation are performed to design, expiain and interpret the experimental results. They are done in COMSOL Multiphysics. Ln a first approach, only the heat equation in 1 D has been implemented in the toolbox. Comparisons between experimental and theoretical results gives us the therm properties of tested materials (ʎ,ρ,c,hs et a). The numerical modeling approach shows that, contrary to AAC or VPB, HLC involves a complex interaction between heat transport and mass transfer through the material. So, simulations on HLC are investigated through the problematic of phase change materials

Full textThe mobilization of arsenic in the environment by naturally occurring processes results in source water contamination. While drinking water represents the main source of exposure to inorganic arsenic, this source water contamination increases the human health hazard. Thus, the maximum contaminant level of arsenic in drinking water was reduced to 10 µg/L and as a consequence new analytical methods and efficient and innovative arsenic removal processes have to be developed and optimized. Here As(III) was quantified by hydride generation atomic absorption spectrometry or by square wave cathodic stripping voltammetry depending on matrix composition. Both chemical and electrochemical processes as coagulation flocculation with Iron(III) salts and electrocoagulation, were optimized to remove arsenic. Their efficiency depends on arsenic speciation, pH, treatment dose and presence of organic matter. These parameters also control the arsenic removal mechanisms

Full textCurrent dynamical models of Solar System formation and geochemical models agree on a likely chondritic origin for the terrestrial water. Indeed, primitive meteorites, called chondrites, have undergone an aqueous alteration process on their parent bodies. Moreover, these meteorites are one of the considered sources for the existence of water in lunar minerals. This thesis lies on hydrogen isotopic ratios and water contents measured using NanoSIMS in the carbonaceous chondrite Paris and lunar soils from the Apollo missions. Chondrules in Paris meteorite seem to have registered a water source distinct from the one of the parent body aqueous alteration. For the moon, water retained in soils is majority formed by implantation of the solar wind hydrogen
