The aim of these studies is the environmental evaluation of the WAELZ slag valorization (in a bulk state or •in substitution to granular). This evaluation needs the determination of wastes or waste materials leaching behavior in specified scenarii. Concerning the use of slag in bulk state we examined the scenario: embankment, filling and embanked road. The pollutants leaching behavior in bulk slag’s has been studied with different chemical backgrounds. This experimental study ha clearly shown that the species release is controlled by their solubility by the surrounding pH and by the nature of solid phases. Concerning the use of slags in partial replacement of granular in construction materials, we have also worked on three kinds of materials (mortar, concrete and sand cement) in which a part of granular is replaced by slag. The dynamic studies of monolithic materials release showed that soluble species release (Na, K, Ca) is well described by a diffusional phenomena and that principal pollutants are non detectable during distilled water leaching. The modelisation of the source term with percolation has been realized considering hydrodynamic model coupled with pollutant diffusion-dissolution model. The shrinking core model/flow with immobile zone is well adapted to describe calcium release. The characterization of phenomena and the identification of the characteristic parameters allow predicting the long term behavior of the material submitted to various leaching scenarii. This global study showed that the slag which was used had a good physical and chemical stability in contact with a concrete material. The use of slag in partial replacement of granular in construction material can be considered favorably

The aim of this work is to characterize a fly ashes solidification-stabilization process with hydraulic binders. First, new additives were choosen for their capacity to trap the two sorts of pollutants present in wastes : solubles salts and metallic species. After a description of different materials used (wastes, cement, additives). The different stabilized wastes have been leached according to a procedure based on a standard AFNOR x31-210. Samples are studied by optical microscopy, SEM, electron microprobe, elementary analyses in order to control efficiency of pollutants immobilization into CSH phases). The second part deals with time evolution of stabilized products. Two leaching tests have been used to study environmental attacks in short experimental times. First one is a soxhlet and simulates the streaming of pure water on samples. Second one is a batch test where samples are immerged into solutions of different nature (water, solutions doped with complexing agents). Stabilized waste leaching depends on different parameters including time. The simple model of pollutants diffusion through cement matrix is inadequate because precipitations modified quickly solubility and materials porosity. In order to connect hydratation reactions to textural modifications of stabilized wastes during their leaching, 1H NMR is used to complement two methods of porosity envestigation :mercury porosimetry and tomodensitometry. Results show that porosity is decreasing at long term and pollutants lixiviations is more and more limited. Evolution of stabilized wastes involved a more efficient immobilization

This research is devoted to the analysis of means used to define stabilization/solidification processes of specific industrial wastes. The selected wastes are a used catalyst containing vanadium V(V) and an activated charcoal polluted by iodine. We have shown that the water absorption capability, which is linked to the waste porosity, is the key factor of a treatment; the choice of the adequate binder for this treatment is suggested by the behavior of the bulk waste during leaching. Two treatment processes, one based on hydraulic binder stabilization and the other based on bitumen stabilization, are developed and tested. In both cases, it appears that the physical and chemical properties of the binder and the mixing of the waste and the binder determine the efficiency of the treatment. Thus we observed that the effectiveness of the hydraulic binder to chemically stabilize the bulk waste is linked to the waste solubility level in the binder leachates. Regarding bitumen, it appears that the treatment efficiency mainly depends on bitumen viscosity. The waste/hydraulic binder mixing process is based on a selected order of constituents’ incorporation and on selected proportions ratio. The waste/bitumen mixing process proved to depend on two parameters: the workability temperature and the residence time at this temperature We propose an empirical model that allows to evaluate the latter. After treatment of the two wastes using both processes, it appeared that although vanadium is reduced in V(IV) by bitumen, it is not more stable. By incorporating vanadium in its hydrates, the hydraulic binder chemically stabilizes the waste. It is therefore more efficient to treat the catalyst. Iodine is not chemically stabilized by these binders. However, by ensuring a greatest physical retention, the bitumen-based process constitutes the best approach for charcoal treatment. This methodology, based on the link between waste and binder, provides acceptable results on the viewpoint of the stabilization/solidification by two different binders. It opens interesting perspectives considering the number of existing hydraulic binders and bitumen

The objective of the study is to characterize the retention of pollutants from wastes solidified with hydraulic binders. The stabilized/solidified wastes are APC MSW (air pollution control residues from municipal solid waste incineration), lead secondary smelting slag and different salts. The binders used are ordinary Portland cement (OPC 55) or blast furnace slag cement (CLK 45) and additives, such as metakaolin. Leaching tests are used in the characterization procedure and modelling of the observed leaching behavior is conducted to improve the description of the physical and chemical phenomena involved in the transport of soluble species. The main results of the study allow to make a distinction between the species whose solubility is not sensitive to the chemical context of the pore solution, and the other species, such as amphoteric metals, whose solubility is sensitive to the context (for example the pH). In the first case, a diffusion or shrinking front model is appropriate. On the other band, a coupled solubilisation/diffusion model must be developed in order to describe the leaching behavior of heavy metals (lead, etc. ) stabilized/solidified with concrete

With the new French laws in the hazardous waste management field, a lot of industrial waste have to be stabilized/solidified before landfilling. This is the case of heavy metal hydroxide sludge generated by the electroplating industry, which have to be stabilized after the 30th of March, 1998. The aim of this work is to study the interactions between this kind of waste and Ordinary Portland Cement (OPC). Simple synthetic hydroxide sludges were used in place of real waste. The perturbation of the hydration of OPC/sludge mixes was carried out using XRD, SEM and adiabatic calorimetry. Preliminary experiments showed that zinc strongly inhibits hydration, so what we have concentrated or work on chromium sludge. Chromium accelerate initial set of OPC. No evidence of real perturbation was observed under a sludge/cement mass ratio of 2. For greater ratios, hydration was strongly affected. The fixation mode of chromium in cement matrices depends on its oxidation state. Chromium III can be present as hydroxide, or associated with calcium silicate and sulfate, and can substitute for alumina in calcium aluminate hydrates. Chromium VI (chromate ion) can precipitate as soluble alkali chromate, and can substitute for sulfate ion in sulfoaluminate hydrates. For instance, we have observed a chromate-substituted sulfoaluminate of calcium and sodium. Finally, a short study of the leaching behaviour of solidified mixes showed a good retention of chromium III. Only chromium VI was found in the leachates

Since 20th century’s end, our society started to take conscience of environmental protection and sustainable development are required to our future blooming. Directives have obliged public authorities, communities, such as industry to be reacted particularly while being implied in research. The cement-manufacturers are also concerned. The process cement-manufacturer requires large quantities of raw materials. The main objective of the thesis is to value industrial by-products by cementitious materials. Context and problem of wastes were discussed, as well as the possibility of valorization such as the cements. The methodology set up for the thesis and its originality are explained. First, the protocol of characterization of mineral wastes was developed. The results in laboratory are promising for the replacement of limestone and clay in the cement’s raw meal and different formulations. The cookings in laboratory allowed obtaining a cement containing 4 phases of Portland. The synthesis in bigger quantity of a formulation in laboratory highlighted good mechanical performances on mortars at the young age. In a second stage, the best formulations were tested on an industrial scale in the ARF’s kiln. The raw meal, mixed by hoppers agitators, was a success. Finally, immobilization of pollutants in a cement matrix of the residues after combustion, resulting from secondary fuels of ARF, was studied to be able to downgrade the waste stabilized/solidified by grading reduction of the material before stabilization/solidification

France, as all industrialized countries, has on its territory many potentially contaminated sites containing coal-tar materials from past industrial activities. Specific remediation technologies have been developed, mainly in North America. Existing treatment technologies include thermal processes (incineration, desorption, vapor extraction. . . ), physical methods (such as solidification/stabilization, vitrification. . . ), chemical methods (extraction, washing) and biological processes to a lower extent. A non-destructive remediation process has been developed here to reduce the overall mass of contaminated materials to be incinerated. In a first step, laboratory feasibility studies have been conducted on coal-tar contaminated rubbles. A specific extraction-washing treatment chain has been developed, with the selection of an appropriate organic solvent for the extraction phase and a detergent for the washing phase of the process. Laboratory results being promising, the next step was to test the process at the pilot and industrial scales. Approximately 600 m3 of coal-tar contaminated rubbles from a mixture of various demolition materials were treated. The process included complete excavation of the rubbles contaminated with coal tar, contaminant extraction and washing to achieve specified cleanup levels for organic contaminants. Hence the extraction-washing process was able to significantly diminish most of the contamination associated with PAH, phenols, inorganic nitrogen compounds and total cyanides in the rubbles. Furthermore, the industrial scale data showed a significant total mass reduction of contaminated materials to be incinerated since the treated rubbles were disposed off on the site. In the third step of our study, experiments at the laboratory-scale were conducted in order to improve the process and reduce the amount of byproducts generated during treatment and requiring offsite disposal. Studies were performed on the biological treatment of the waste water containing complex organic pollutants such as phenolic compounds, on the mass reduction of wastes smaller than 10 mm with screening tests, and on the solidification/stabilization trials of other solid contaminated byproducts. The process should be now tested on other sites with rubbles contaminated with coal-tar having different physico-chemical characteristics

Dredged materials are necessary to the give a safe access to the harbours and a high environment quality to them. So an important volume of fine marine sediments is produced. Consequently the management in respect with a sustainable development need to find alternative solutions to the damping at sea or to the storage on shore. Many research works have been run on the valorisation of fine sediments but actually, all of them consider only one specific sediment, and the results are difficult to be applied to other sediments because of the lack of recommendation or criteria for the choice of valorisation in public works or civil engineering (Chapter I and II). For any study of valorisation, all characteristics about marine sediments must be well defined taken into account the variability of them. The chapters (III and IV) are focussed on the properties of a series of harbour sediments (9) according their origin. Physical properties, sedimentation and consolidation parameters are studied and finally a recap of all characteristics are given and a list of them are suggested as a list of parameters required to look at a valorisation of sediments. The choice of the type of valorisation are depending i) on these properties and parameters and ii) on the mechanical and environmental performances relative to the final application. The sediments have been treated to improve their characteristics through a stabilisation / solidification techniques using cement and lime (Chapters V and VI). The reuse for embankment and for road sublayers is considered. The reuse of natural sediment or weakly mixed with cement sediment have been discussed. A construction of an embankment in a confined site is possible in respect with the needed mechanical and environmental properties
