Texto completo da fonteThe fine fraction of WtE-BA, consisting of particles smaller than 2 mm, represents 30-40% of the WtE-BA mass. Due to the high levels of trace metals it contains, it is rarely reused. However, its chemical composition and granulometry make it a promising candidate for use as a secondary raw material in cementitious materials. Additionally, the presence of metallic aluminum in WtE-BA could allow it to serve as a pore-forming agent in the production of aerated materials. The initial section of this thesis concentrates on the physico-chemical characterization of the fine fraction of WtE-BA, with the goal of utilizing it as a pore-forming agent. The objective is to evaluate the quantity and reactivity of metallic aluminum. The second part of the text concentrates on the experimental approach to formulating cementitious materials. It is divided into three stages. First, the parameters that influence the properties of interest were identified during a study on cement paste. The optimization of formulation parameters is performed on mortar and is accompanied by physical, microstructural, and environmental characterizations. The optimal formulations are then implemented on concrete to verify the validity of the experimental approach. The results indicate that this approach is effective in producing mortars and concretes with WtE-BA. These materials have densities, compressive strengths, and thermal conductivities comparable to those of aerated reference materials. The pores of materials with WtE-BA differ from those of aerated reference materials in their smaller size and irregular shape. Leaching tests conducted on concrete and mortar showed low levels of pollutant release, which is generally within the environmental thresholds set by the French legislation (Arrêté du 18 novembre 2011) and the Dutch Soil Quality Decree

Texto completo da fonteCurrent challenge of Municipal Solid waste Incineration (MSWI) bottom ash management lays in its valorization, mainly to be used in road construction projects. The process must take into account environmental regulations and conduct rigorous monitoring from production to utilization. One constraint in the assessment of MSWI bottom ash is related to quality criteria which is becoming more restrictive. Among potential pollutants that can cause environmental use restrictions are metal trace elements (MTE), whose behavior based on weathering and grain size is not yet well known and represent one of greatest concern. In this thesis, the developed research approach defined the favorable conditions for Cu, Cr, Pb, Sb, Ni and Zn release. The aforementioned approach is based on three pillars: The first pillar focuses on the development of a pertinent characterization method for bottom ash (including the polluting organic and mineral fraction) aiming at a better assessment of its properties. The initial study matrix, taken from an industrial site, was carefully analyzed from both, physico-chemical and environmental performances. Geochemical modeling based on physico-chemical and leaching data, allowed to identify the main mineral phases and to simulate material behavior with the purpose of predicting the evolution of MSWI bottom ash in specific storage or valorization conditions. The second pillar describes the impact of weathering conditions and size partitioning on MSWI bottom ash quality evolution. Three different weathering conditions (natural on industrial scale heap; accelerated on small heap; and forced) were studied. The results showed that changes in the chemical and mineralogical composition of MSWI bottom ash as well as in its size fractions are more significant when the weathering proceed. The natural accelerated weathering and the forced carbonation limited the leaching of Cu, Pb and Zn, whereas, the leaching of Cr, Sb, Cl and the SO42- increased as pH decreased. The third pillar focuses on the study of MSWI bottom ash alternative utilization as secondary raw material for the typically practiced road sub-layers construction. It consisted of incorporating MSWI bottom ash in a self-compacting material used for pavement sub-layer or coated road shoulders structures. A formulated material was obtained by mixing MSWI bottom ash, water and cement as a hydraulic binder. The results of the mechanical, geotechnical and environmental assessment are promising for MISWI bottom ash potential use in road construction

Texto completo da fonteValorisation of Municipal Solid Waste Incineration Bottom Ash (MSWI-BA) in building materials in order to reduce their expansive storage in technical burying center and preserve the natural ressources constitutes a challenge. A hindrance of this valorisation is the pollutant potential of metals (especially mineral traces elements MTE) and anions likely to be released in use scenarios. This thesis evaluates the impact of incorporation of MSWI-BA into ready-mix concrete formulation. It helps to improve the understanding of MTE and anions behaviour in different leaching conditions and to find adequate solutions to limit their mobility. The first part presents the technical and environmental performances of ready-mix concrete formulated by partially replacing of the natural aggregates with different size fractions of BA incorporated at different substitution rates. The results demonstrate that the environmental performances of the scenario comply with the regulatory requirements of the Netherlands. On the other hand, the compressive strength is reduced by half compared to the standard formulation. Pretreatment of MSWI-BA could improve the mechanical performances. The second part describes the influence of thermal and chemical pretreatments on the mobility of MTE. The results show that the efficiency of the thermal treatment depends on the temperature and the target element. Optimised chemical treatment used in this study appears to be more effective. The third part, dedicated to the geochemical modeling of BA behaviour in leaching scenarios, allowed us to identify the mineralogical phases that control the mobility of MTE. It shows that the majority phases impose the parameters of the solution such as the pH and consequently, influences on the release of the MTE. This knowledge facilitates the definition of the possible pretreatments to be applied on the MSWI-BA before its valorisation

Texto completo da fonteIn a world where circular economy and the valorization of raw materials is taking a greater importance, municipal solid waste incineration (MSWI) bottom ash is identified as potentially renewable resource in the construction field and more specifically in cementitious materials like mortar and concrete. Given the origin of the bottom ash and in order to have a better cement/MSWI bottom ash compatibility, the fraction used was as refined as possible by removing ferrous, non-ferrous and unwanted materials. The choice of the cement used is a critical factor as well because it affects the quality of the end product since MSWI bottom ash has particular physicochemical properties. The work in this PhD studies the advantages of using a sulfo-aluminate cement to valorize an improved 0/2 mm fraction of bottom ash that has been developed to be used in cementitious matrices. The first part presents the results of the mortar sample mixes containing bottom ash in a substitution by volume of the standard sand. To better highlight the effect of using a sulfo-aluminate (CSA), CSA mortars containing bottom ash were compared to a Portland cement (OPC) mortars, with substitution rates of 25 %, 50 %, 75 % and 100 % were used. A study of the porosity was then conducted at 90 days ; it shows that the pores larger to 50 nm are remarkably less present for CSA mortars. This thesis brings forward a major and innovative result : the level of alkalinity of the mortar plays an important role in the release of hydrogen gas after mixing and before setting. The presence of these gases creates large porosity in the hardened mortar samples. The second part studies the physical and microstructural aspects of the mortars after being immersed in aggressive environments : pure water and sulfate solution. The substitution rates used in this experiment were 50 % and 100 % by volume as well as the reference mortars with no bottom ash. These samples were then studied in the SEM which showed that CSA/bottom ash mortars were clearly less affected than the OPC/bottom ash mortars. This was highlighted by the porosity, the cracking and the depth of degraded zone
