Der volle Inhalt der QuelleThe work described in this manuscript is part of research programs dedicated to the study of the aging of nuclear civil engineering structures, initiated by the Institut de Radioprotection et de Sûreté Nucléaire (IRSN) and conducted within the Laboratoire Matériaux et Durabilité des Constructions (LMDC) in Toulouse. This research falls within the framework of a project aimed at extending the operational lifespan of French nuclear power plants. The objective of this study is to contribute to the acquisition of knowledge related to the impact of the development of certain internal pathologies within irreplaceable components of nuclear power plants, such as containment structures, on the transport characteristics of concrete. It is worth noting that the behavior of these materials at the containment level is of crucial importance in the assessment of the safety of nuclear installations, as containment structures represent the third and final barrier of protection against any potential release of radioactive products into the environment. Professionals responsible for concrete durability tests face a major challenge: evaluating the transport characteristics of concrete affected by Internal Swelling Reactions (ISR). These pathologies are generally associated with two types of chemical reactions: Delayed Ettringite Formation (DEF) and Alkali-Aggregate Reaction (AAR). When these reactions develop, tensile stresses appear in the concrete, leading to the formation of cracks in structures affected by these pathologies. In this context, the research conducted as part of this thesis focuses on two main aspects: measuring the air permeability of concrete subjected to internal swelling reactions, covering a range of saturation levels from partially saturated (80% Sr) to completely dry. Furthermore, all nuclear civil engineering structures are reinforced with passive and active reinforcements, so this study takes into account the presence of reinforcements in various arrangements. The data collected in this study allow for the assessment of the evolution of transport properties of concrete affected by ISR based on the generated expansion, induced cracks, and the degree of concrete saturation. An innovative device has been specially designed for this research. This new protocol allows for the measurement of air permeability while providing the opportunity to assess the anisotropy of this property by quantifying it in two directions on the same sample, without confinement pressure that can affect permeability data. Moreover, it allows for an analysis of how air permeability evolves in relation to the presence of reinforcements in different configurations, while taking into account the development of internal swelling reactions. The results obtained during this study have improved our understanding of transport properties in concrete affected by ISR, with or without reinforcements, and have generated experimental data that will enrich the databases used to establish advanced models capable of predicting the long-term behavior of concrete affected by ISR, considering both expansion and modifications to transport characteristics. These models will help predict any necessary interventions on structures, thus contributing to reducing the costs associated with deferred repairs

Der volle Inhalt der QuelleLes mesures de la perméabilité au gaz sont effectuées sur des éprouvettes cylindriques en béton soumises à des températures allant jusqu'à 150 °C et à une compression uniaxiale jusqu'à la rupture. Les résultats expérimentaux révèlent que les effets de la température et de l'endommagement peuvent être découplés pour l'estimation de l'évolution de la perméabilité. Ils nous ont permis de proposer une relation reliant la perméabilité à l'endommagement et à la température. Cependant, cette relation ne peut s'appliquer que dans le domaine pré-pic du comportement du béton où le béton demeure microfissuré. Afin de dépasser cette limite pour pouvoir modéliser également l'accroissement de la perméabilité en phase post-pic, un autre paramètre, qui est l'ouverture de fissure, est intégré dans la relation entre la perméabilité et l'endommagement.
Cette problématique, faisant l'objet d'une modélisation, est exploitée selon deux approches. La première se base sur la définition d'une loi de raccordement entre les lois existantes d'évolution de la perméabilité avec l'endommagement et l'ouverture de fissure. Avec cette approche les tendances observées expérimentalement sont retrouvées. La deuxième approche consiste à relier d'un point de vue mécanique l'endommagement avec l'ouverture de fissure puis d'appliquer la loi de Poiseuille pour déterminer la perméabilité. La validation expérimentale de cette approche, permettant de déboucher vers un modèle continu capable de reproduire les variations de perméabilité d'une structure, constitue une des perspectives de notre travail.

Der volle Inhalt der QuelleThis thesis aims at characterising and modeling the mechanical behavior of concrete at the mesoscopic scale. This model is to represent the concrete as a heterogeneous medium, taking into account aggregate and cement paste respecting the grading curve. The model parameters describe the mechanical and thermal behavior of cement paste and aggregates. A program of random granular structure valid in 2D and 3D has been developed. This program is interfaced with the Finite Element code CAST3M in order to compute the numerical simulations. A method for numerical representation of the inclusions of concrete was also developed and validated by projection of the geometry on the shape functions, thus eliminating the problems of meshing. Firstly, the model is studied in order to optimize the geometrical model of the inner structure of concrete in terms of the meshing strategy and the smallest size of the aggregate to be taken into account. The results of the 2D and 3D model are analyzed and compared in the case of uniaxial tension and uniaxial compression. The model used is an isotropic unilateral damage model. The model allows to simulate both the macroscopic behavior but also with the local studies of the distribution of crack and crack opening. The model shows interesting results on the transition from diffuse to localized damage and is able to reproduce dilatancy in compression. Finally, the mesoscopic model is applied to three simulations : the calculation of the permeability of cracked concrete ; the simulation of the hydration of concrete at early age and finally the scale effect illustrated by bending computation on notched beams

Der volle Inhalt der QuelleThe aim of this work is to understand the influence of the geometric parameters of envelope eco-materials, such as hemp concrete, on the mechanisms of coupled heat, air and moisture transfers, in order to predict behavior of the building to control and improving it in its durability. For this a multi-scale approach is implemented. It consists of mastering the dominant physical phenomena and their interactions on the microscopic scale. Followed by a dual-scale modeling, microscopic-macroscopic, of coupled heat, air and moisture transfers that takes into account the intrinsic properties and microstructural topology of the material using X-ray tomography combined with the correlation of 2D and 3D images. A characterization campaign of physical and hydrothermal properties of the hemp concrete manufactured in the laboratory was carried. It focused on studying the impact of aging, thermal and hydric state of the material on these intrinsic properties. The results show an excellent thermal insulation and natural moisture regulation capacity of hemp concrete. Then, a microscopic characterization by different imaging techniques was performed. The 3D reconstructions of the real material scanned with X-ray tomography at different resolutions show that hemp concrete has several scales of porosity, ranging from micro-porosity within the binder and hemp shiv to the inter-particle macro-porosity. The hydromorphic behavior under hydric solicitations was studied. The results of the 2D digital image correlation and X-ray tomography coupled with the volumetric image correlation show the nature of the behavior of hemp concrete subjected to different relative humidities. In fact, the hemp shiv undergoes greater deformations than the binder, thus causing changes in the microstructure of the material. On the modeling part, a model of coupled heat, air and moisture transfer in porous building materials was developed using the periodic homogenization technique. The homogenized tensors of diffusion and thermal conductivity were determined numerically. Then, a confrontation between the results of the calculation of the macroscopic diffusion coefficients and the experimental results obtained at the LaSIE was carried out. It highlights the quality of the prediction. In addition, the thermal conductivity of the solid phase was thus deduced. The results obtained in the framework of this PhD thesis have highlighted the influence of the hydric and thermal state of the hemp concrete on these intrinsic properties and its very heterogeneous microstructure. They also revealed the limitations of phenomenological approaches based on the establishment of the balances of mass, amount of motion and energy

Der volle Inhalt der QuelleCivil engineering structures are constantly subjected to desaturation/re-saturation processes depending on the surrounding conditions. This is particularly the case when it comes to concrete structures for the deep geological storage of radioactive waste. It is fundamental to understand the water transfer phenomena that occur during these water rebalancing phases to assess the sustainability of these structures. This thesis presents both an experimental and a numerical simulation study on the main mechanisms that are involved during the rebalancing process within cement-based materials. First, the experiments carried out make it possible to characterize the hydric behaviour of the materials through the acquisition of the main transfer parameters (porosity, sorption isotherms, permeability to liquid, vapour and gas). This will allow discussion of the relevance of different numerical and/or empirical approaches to their prediction in the case of cement-based materials. Then, the study focuses on the phenomena involved in a water rebalancing process between two samples, through various water transfer experiments (drying, soaking of steam and liquid water). A methodology based on non-destructive evaluation of materials is developed for the determination of moisture content profiles. A suitable approach is proposed for the modelling of moisture transfer mechanisms in cement-based materials, based on a porous network model for the prediction of transfer parameters developed by Ranaivomanana et al. A better prediction of these phenomena taken individually will provide the required information for the modelling of the global process

From the results, the infiltration rate varied from 0.00 to 6.684 $ times$ 10$ sp{-7}$ m/s. The minimum value was recorded at the reservoir 55 with 1% of total solid manure and the maximum value was recorded with same reservoir with positive pressure to water.

Der volle Inhalt der QuelleThe relation between damage and permeability is of great importance to evaluate the consequences of a mechanical loading on the hydraulic integrity of sensitive concrete structures like containment buildings of nuclear power plants. An elastic plastic damage constitutive law for the mechanical behaviour is first developed. The model is validated on elementary and structural applications with a special focus on the efficiency of the numerical tools (tangent matrices). A relation between water saturation (drying), damage and permeability is then proposed, based on theoretical and experimental observations. Finally, a Representative Structural Volume of a containment vessel is studied to highlight the influence of hygro - mechanical loading on the hydraulic behaviour (distribution of gas pressure)

Der volle Inhalt der QuelleThe study of sealing containment vessels of nuclear power station (1300 and 1450 MWe) is a major challenge to ensure the safety of the population. During a Accident with Loss Of Coolant, the containment is subjected to a pressure of 5 bar, 141 ° C temperature and relative humidity close to 100%. Under these extreme conditions, it should remain sealed. To ensure this protection, it is necessary to study the material that makes up these containments: concrete. Today, many studies are used to characterize the permeability of concrete using dry nitrogen as fluid percolating with mechanical loading (compression) up to 150 ° C. However, we know little about the evolution of the nitrogen permeability of concrete with different water contents coupled with mechanical loading. More, the gas used for the measurement of permeability is not steam as accident conditions described above. To be closer to accident conditions, we measure the nitrogen permeability of hollow cylindrical tubes 11 * 22 made of concrete with different percentages of water subjected to compression at ambient temperature. Then we designed an experimental bench to submit concrete cylindrical specimens coupling thermo-hydro-mechanical mixtures by injecting different nitrogen and water vapor, controlled pressure and measuring leakage rates in nitrogen and steam. These tests are performed under mechanical loading compression in pre and post-peak

Der volle Inhalt der QuelleThe aim of the present research was the valorization of a by-product coming from the hydrolysis of starch as an admixture for mortars and concretes. The use of this by-product allowed an extended time of workability, a limited bleeding, and reduced plastic shrinkage and permeability. The mechanical strenghts at 16 hours were improved and those at 28 days remained constant. Moreover, it was shown that the formulation of the standard mortar is not adapted to caracterize the effect of a plasticizer on the time of workability. The water/cernent ratio is a dominant factor to ensure this workability. As bleeding can be prevented, the performances hardened concrete does not decrease
