Full textSince the discovery of the slow relaxation of the magnetization of compound Mn12-ac, much groups in the molecular magnetism field have reported the synthesis of clusters showing such properties. The common "one -pot" synthetic method used for cluster synthesis doesn't allow much control of the spin ground state and magnetic anisotropy of the specie, those parameters being responsible for Single-Molecule Magnet behaviour. The method selected here is based on a stepwidse approach and the use of cyanide ligands as bridges. A judicious choice of the ligands allows to crystallize polynuclear bimetallic compounds, and to increase the control of the cluster's geometry and spin ground state. In that way, a trinuclear linear Cr2Ni complex (S=4) and a tetranuclear square Cr2Ni2 complex have been obtained, but don't behave like Single-Molecule Magnets. The anisotropy of a cyanide bridged polynuclear complex is closely related to the local anisotropy of its ions. The study of Ni(II) mononuclear complexes, and especially anisotropic ones, is thus crucial. A series of Ni(II) mononuclear complexes of very distorted geometry have been crystallized and studied by high fields and high frequencies EPR and FDMRS, indicating a huge anisotropy for that kind of compounds, which seems to be controled by the organic ligand. Three polynuclear complexes CrNi2 (S=7/2), CrNi3 (S=9/2) and Cr2Ni7 (2 spins S=7/2) have been obtained using the previous complexes as precursors and studied by EPR. Those species show important anisotropy parameters. Their low temperature study indicates a zero field magnetic tunnel effect phenomenon

Full textThe localizations of high-technology activities, essential for economy and society, are very studied. The modelisation represents the necessary evolution for their study. The morphology of hagerstrand's classics diffusion models and his school retranscribe well the diffusion of high technology activities for the 1954-1990 period. A double-level geographical structure, one national regional, and the other local, comes out geographical study. Graphic modelisation allows, on the foundation of explanatory choremes previously defined, to build an hypothetical diffusion model for high technology activities. Choremes matrices and spatiotemporals trajectories allow the built of evolution scenarios. An evaluation by classification shows a god approch of the reality of national regional level, but more approximative results for local level. Mathematical modelisation allows to continue the study of graphical modelisation hypothesis overcoming the limits of this tool. This modelisation is done through geographical unities, spaces with varying fronteers within the time. Into the geographical unities, diffusion is worked out according to various criters with rare linear effect. The evaluation of the results according to residual variance value shows a good description of national regional diffusion level. The local diffusion, often approached in its main lines, includes in the detail notable imprecisions. Model opens methodological ways concerning graphic models and the relation between tools of modelisation

Full textThis dissertation compares senior civil service reforms in France and Great-Britain in a socio-historical perspective. Whereas these countries are considered as most different cases in the literature on public administration and managerial reforms, I suggest that their historical trajectories display striking similarities in the long run, related to issues of regulation of the administrative labour market. Building on analytical concepts from the sociology of professions and the sociology of labour markets, I argue that in both countries the politics of senior civil service can be explained as a competitive dynamic between actors struggling to define and control the rules of entrance and circulation on the administrative labour market. Four institutional dynamics – professional, administrative, political and educational - are at the core of this evolution, which I suggest can be explained in three successive historical periods: the politics of external closure on the administrative labour market and the professionalization of the “generalists” before the second World War; the politics of centralization and the attempts to create an internal labour market at the top of the State; and finally the opening up of the administrative labour market and the politics of re-regulation at the end of 20th century. This long term historical analysis leads to characterize two ideal-typical models of administrative labour market – a professional one and an organisational one - based on different types of internal segmentation

Full textWe study the annihilation radiation of Dark Matter in the Galactic halo, under the assumption that it is made of weakly interactive massive particles (WIMPs) and focusing in particular on specific candidates such as the supersymmetric neutralino, the lightest Kaluza-Klein particle in scenarios with unified extra-dimensions, and on generic super-heavy candidates. We consider three channels of the annihilation flux from the Galactic center: synchrotron radiation, gamma-ray and neutrino flux. Using the present observations we are able to put constraints on the physical parame-ters of Dark Matter particles and distribution, while the expected sensitivity of future experiments allows us to discuss the prospects of observing Dark Matter candidates in the near future. We also study the possibility of using stellar structure arguments and helioseismic observations to constrain the properties of Dark Matter particles. In the second part we discuss the propagation of ultra-high energy heavy nuclei in an extra-galactic magnetic field, keeping into account ail relevant energy losses. We then study numerically such process and use the results of simulations to analyze different models for the origin of ultra-high energy cosmic rays recently appeared in literature

Full textThe Antares collaboration has chosen to build an underwater telescope in the Mediterraneen, at a depth of 2500 m, to detect high energy (>100 GeV) cosmic neutrinos, thus opening a new window on the Universe, that could resolve certain Particle Physic and Astrophysics issues. This detecter is composed of 12 vertical lines with 900 photomultipliers. Neutrinos are detected thanks to the Cherenkov light produced in water by charged particles created in neutrino interactions near the détecter. The aim of this work is the study of Antares performance for the detection of the electronic neutrino interaction in the instrumented volume using a Monte Carlo simulation. The method allows the determination of the incident energy with an excellent resolution (20%) which is much smaller than what is obtained from muons induced by muonic neutrino interactions at several kilometers below the detecter. Firstly, this work consisted to study the reconstruction of contained showers of particles in the detecter resulting of charged current interactions of electronic neutrinos. Secondly, this mode of detection has been used for the study of the diffuse neutrino flux, resulting from the neutrino emission of unresolved sources and that can be isolated from the atmospheric neutrino background at high energy. The Antares sensitivity is found to be 5 10ˉ7 GeV cmˉ ² sˉ ¹ srˉ ¹ after one year of data taking for energies above 3 TeV and for a model with an E ˉ ² energy spectrum

Full textThe HESS experiment (High Energy Stereoscopic System) consist of four imaging atmospheric Cherenkov telescopes to study southern hemisphere astrophysical sources above 100 GeV. The first part of this thesis studies the extended sources observed along the Galactic plane with this instrument. A multi-resolution analysis based on wavelets has been adapted to the VHE (Very high Energy) data for a better study of morphology, and has been tested on Monte Carlo simulations. A rnorphological and spectral analysis has allowed the selection of sources with a powerful spatially-coincident pulsar and to make a list of pulsar wind nebulae candidates based on energetic criteria. The second part of this thesis investigates the origine of the asymmetric morphology of the nebulae by studying the interstellar medium and show that a majority of the PWN candidates have a matter gradient near the pulsar position which is compatible with the hypothesis of an asymmetric reverse shock. Finally, an energy-dependant morphological analysis is applied to HESS J1825-137, the archetypal VHE PWN, and reveals high-energy electrons near the pulsar and a hardening of the spectral index far from it : we propose to model this source with a time-dependent spectral rnodelling. This model reproduces very well the data with reasonable parameters. It allow us for the first time to constrain the time evolution of the magnetic field in a PWN together with the initial characteristics of the pulsar, and confirms the presence of relic electons in

Full textCivil servants are often considered as a coherent group of individuals ; they are analysed as actors, subjects, victims and instruments of analysis before being the object of analysis. And yet, if we take this category as being selfevident, we are in danger of forgetting that its limits, its make-up and its position at the intersection of the "administrative" and the political, are not, on the contrary, self-revealing. Having established this point, questions must be asked pertainning to the manner in which this group was progressively formed, the objective differentiation process it has undergone ; we must understand how this category has become reified in social terms and what effects this has had ; lastly we must recognize that precize definition of this category will emerge after contradictory debate. The object of this thesis, then, is to study the social construction of this group

Full textThe need for resources in High Performance Computing (HPC) is generally met by scaling up server farms, to the detriment of the energy consumption of such a solution. Accelerating HPC application on heterogeneous platforms, such as FPGAs or GPUs, offers a better architectural compromise as they can reduce the energy consumption of a deployed system. Therefore, a change of programming paradigm is needed to support this heterogeneous acceleration, which trickles down to an increased level of programming complexity tackled by software experts. This is most notably the case for developers in quantitative finance. Applications in this field are constantly evolving and increasing in complexity to stay competitive and comply with legislative changes. This puts even more pressure on the programmability of acceleration solutions. In this context, the use of high-level development and design flows, such as High-Level Synthesis (HLS) for programming FPGAs, is not enough. A domain-specific approach can help to reach performance requirements, without impairing the programmability of accelerated applications.We propose in this thesis a high-level design approach that relies on OpenCL, as a heterogeneous programming standard. More precisely, a recent implementation of OpenCL for Altera FPGA is used. In this context, four main contributions are proposed in this thesis: (1) an initial study of the integration of hardware computing cores to a software library for quantitative finance (QuantLib), (2) an exploration of different architectures and their respective performances, as well as the design of a dedicated architecture for the pricing of American options and their implied volatility, based on a high-level design flow, (3) a detailed characterization of an Altera OpenCL platform, from elemental operators, memory accesses, control overlays, and up to the communication links it is made of, (4) a proposed compilation flow that is specific to the quantitative finance domain, and relying on the aforementioned characterization and on the description of the considered financial applications (option pricing)

Full textLn the context of the search for brown dwarfs and giant planets companions to stars, as well as circumstellar disks, a first part of my work has been devoted to the study ofthe detection capabilities performed by high contrast and high angular resolution instruments. 1 have been, mainly, interested by the instruments, which presently equip the large ground based telescopes, and which are composed of an adaptive optics system and an infTared camera, coupled with a stellar coronagraph. 1 have been particularly involved into the integration and test phases of the Nasmyth Adaptive Optics System NAOS, presently installed at the UT4 telescope of the ESO Very Large Telescope, in Chili. 1 also developed a model to study and to predict the detection capabilities performed by su ch instruments as a function of the detector modes, the instrument characteristics, the observing configurations or the atmospheric conditions. Thinking of the limitations and the optimization of the observing detection performances has been crucial for the second part of my work, dedicated to the search for low mass companions to stars and circumstellar disks. Two types of targets have been found ideal for this study: the young, nearby associations due to their evolutionary status and the stars with planets, indirectly detected by the radial velocity measurements. I present the detection of severa! substellar candidates in the young, nearby associations Beta Pictoris, MBM 12 and Tucana-Horologium, as well as an unprecedented work on the fraction of stellar companions and of brown dwarf companions among these stars. 1 also describe the recent results concerning the discovery of faint companions in the circumstellar environment of stars with planets and 1 present the detection capabilities performed thanks to our deep imaging strategy

Full textThe objective of the thesis is a contribution to the study of the phenomena brought into concrete with an increase of temperature and particularly the evolution in the microstructure. The first part presents a Thermo-Hydro-Chemical model describing the principal evolutions of the concrete behaviour under thermal loadings. The second part gives the definition retained for the characteristic dimension of the pore. A differential equation relating to the function giving new characteristic dimension of a pore heated according to initial characteristic dimension is presented. The experimental study calls upon various techniques characterising the porosity and the distribution of characteristic dimension. The results obtained by mercury porosimetry, by integrating the differential equation, make possible to check the assumption of uniform erosion of the pores for a field of access radius and a given field of temperature

Full textThis research relates to three of the seven valleys of Lavedan which develop in the extreme southwest of the Hautes-Pyrénées : the valley of Azun, the valley of Cauterets and Davantaygue. It proposes a synthesis of knowledge on the occupation of ground since the first indices of frequenting until the beginnings of the Modern time starting from an exploitation of the historical and cartographic sources traditional and many archaeological prospecting campaigns on the high mountain. If the first material indices of a frequenting go up at the Bronze age, it's finally at the Middle Age that one attends the fixing of the soils and the habitat according to similar methods with what was observed elsewhere, but with different rhythms according to valleys. The settlement seems to have been established in several successive jumps. The first phase of swarming, decisive, sees its apogee with the turning point of Xe and XIe centuries, then the continuation of the growth will be translate rather variously according to valleys. This dynamism continues in Modern time with true enterprises of colonization and the birth of new hamlets

Full textThe aim of this study was to improve the properties of composite blocks for a new class of high performance composites for dental CAD/CAM via high-temperature high-pressure polymerization (HT/HP). Polymerization under HT/HP results into a more homogeneous polymer network with improved mechanical, physical and viscoelastic properties and a very significant decrease in monomere release. In addition, our study also shoxed that 200 MPa is an optimum pressure that allows to reach this set of superior properties. Moreever, composite blocks were made by a new method of infiltrating a ceramic network with monomer, wich resulted in PICN (Polymer-Infiltrated-Ceramic-Network) with improved mechanical, physical and chemical properties. In conclusion, this study introduced a new generation of composite blocks (PICN) with improved properties, blocks that may find clinical applicability in CAD/CAM dentistry in the near future

Full textThe research on biodemographical anthropology worked out on the community of Chiomonte(Haute Vallée de Suse), from 1670 to 1929, and of L’Argentière-la-Bessée (Hautes-Alpes), from1690 to 1889, has allowed the analysis of the changes in the periods considered in these twocountries.The analysis of births has worked out an overall view of the two populations both from a biologicdemographicperspective and from and economic-cultural one.The analysis of deaths has highlighted the importance of environmental factors on death, although ithas been possible to define that through better conditions of life, infantile and juvenile mortality ratecould decreased as well as old aged people mortality increased.Culture, society, economy and religion are the main factors which influenced marriage behaviors ;also environment played an important role.Families’ reconstructions in Chiomonte enabled us to understand that economical changes whichoccurred from 1670 and 1830 had different consequences on the structure and the lineage of thefamily. The increase of life time led to an increase of marriages and at the same time the decrease ofinfantile mortality determined the rise of children who reached the reproductive age.On the other hand, the age of partners at their first marriage, the number of children, theprotogenesic and intergenesic intervals remain constant

Full textThis study concerns an electricity storage system based on thermal energy storage. Its overall purpose is to convert electricity produced by renewable energies into heat when the supply exceeds the demand. This heat is stored for a few hours and converted back to electricity when there is a need for it. The proposed system relies on a high temperature sensible thermal energy storage technology known as the gas/solid packed bed thermal storage. This storage comes with a charging loop and a thermodynamic cycle to carry out the heat to electricity conversion. In this study, two main architectures are considered for this cycle: a simple gas cycle and a Joule/Rankine combined cycle. Each component is modeled with an appropriate level of detail in order to create a global model of the system. This model is used to carry out a thermodynamic analysis. This study calculates the global exergy efficiency of the whole process, which is close to exergy efficiency of a combustion cycle. A detailed exergy analysis of the storage allows to identify the main phenomena behind the availability losses of this component. It shows that it is possible to increase the efficiency of the storage by modifying its sizing. Apart from this study, an economic analysis shows that regardless of its low energy and exergy efficiencies, the gas cycle comes with limited investment costs which insure an interesting profitability. In terms of storage cost, the proposed system is close to other electricity storage solutions like batteries

Full textOne of the major objectives of communication systems is the ability to transmit data at the highest possible rates. The ever-growing user demand for wireless communication already exceeds capacities of present networks.In order to solve this problem, we introduce communication systems based on terahertz (THz) high-frequency carriers, whose frequencies are high enough to support data-rates higher than a hundred of gigahertz. In particular, we are interested in the development and the integration of a high data-rate detector intended for THz wireless communication.We use a GaAs High-electron-mobility transistor (HEMT) as detector. Unlike existing detectors such as Schottky diodes, the transistor studied in this thesis offers advantages in terms of cost, compactness and performances. In particular, the output impedance is more suitable for high data-rate integrated circuits whose input impedance is 50 Ohm. We present the characterization of the detector in terms of sensitivity and modulation bandwidth, demonstrating for the first time its ability to be used for high data-rate communications. The transistor's integration, essential for real communications, is detailed.A wireless THz communication is demonstrated around 0.200 THz and 0.309 THz. For the first time, an error-free transmission at data-rates up to 8.2 Gbps is demonstrated, using a GaAs plasma wave HEMT and a 0.309 THz carrier frequency. Finally, we present new transistors with integrated antenna, allowing communications at higher data-rates and with a longer range, thanks to a better sensitivity

Full textThe River Selle is a non-channelised stream in the Artois-Picardy basin and is considered as a priority waterbody by the Artois-Picardy Water Agency. The aim of this work was to study the spatio-temporal behaviour of several substances at different time scales, ranging from low-frequency (grab sampling, passive samplers) to high-frequency monitoring. More specifically, tracers of pollution reflecting urban, agricultural and industrial contamination (nitrates, phosphates, trace metal elements, pesticides, pharmaceutical residues, dissolved organic matter) were investigated. We confirmed that the River Selle is mainly fed by a nitrate-rich groundwater. Besides, the nitrates and atrazine concentrations in the river water were similar to those found in the groundwater. At the upstream of the river, the land-use is mainly dominated by agriculture whereas most of the urban islets are located at the downstream of the river. Consequently, during dry weather, ultra-trace concentrations of some pesticides and pharmaceutical residues were recorded and phosphate levels often exceeded 0.2 mg L-1. Due to the minor flow input of the wastewater treatment plants into the river, metallic contamination in the River Selle (particularly Gd and Zn) is quite low despite the high concentrations measured in wastewater effluents. Water quality issues during storm events were identified by high-frequency monitoring. Significant but time-limited peaks in phosphorus and organic carbon were observed, while nitrates were diluted. The composition of dissolved organic matter was studied by fluorescence spectroscopy. The spectral signature of different types of water (groundwater, surface water and wastewater effluents) was characterised as well as the origins of this organic matter (autochtonous vs allochthonous). Finally, these results enable to discuss qualitatively the future effects of climate change at a regional scale on the evolution of the water quality of the River Selle

Full textThe thesis is devoted to an extension of the existing continuous wave high frequency electron paramagnetic resonance (cw-HF-EPR) spectrometer in order to work in a pulsed mode. The thesis is split into two parts. Whereas the first part is devoted to our attempt to develop a pulsed HF-EPR spectrometer which operates close to 285 GHz, the second experimental part illustrates the application of the technical developments presented in the first part to the study of single molecule magnets (SMMs) and of single layers of graphite (graphene). In the development part, a detailed description of the HF-EPR spectrometer is given together with the basis of Quasi-Optical propagation. This theoretical summary is then applied to the existing quasi-optical bridge for the propagation of microwave (MW) and to the building up of a Fabry-Pérot resonator. The EPR signal is recorded by a superheterodyne detector optimised for a 283. 2 GHz frequency, which was implemented during this work and replaces a slow bolometeric detection suitable only for multi-frequency cw-HF-EPR. The design and construction of a Fabry-Pérot (FP) resonator, necessary to enhance the MW excitation power, are also described in detail together with a newly developed rotating holder for single crystal studies. These two new devices were then successfully applied in the experimental part of the thesis (two chapters). First, a complete study of tetrairon(III) Single-Molecule Magnets was performed. After a powder study, a single crystal study performed with the rotating sample holder allowed obtaining refined parameters for the magnetic anisotropy, which are necessary for a deeper understanding of the relaxation processes. The second experimental chapter is devoted to graphene (2D crystal). In this chapter, the high performance of the Fabry-Pérot cavity led to the observation of outstanding quality of graphene expressed by a charge carrier mobility exceeding 10^7 cm^2/(V. S)

Full textThe railroad track, booming, at the end of the 19th century in the industrial countries of Europe, allowed the aristocracy and the " nouveaux riches " to move more quickly around the continent. They soon flocked to the banks of the lake " Léman ", particularly in the region of Montreux, known under the name " Rivièra Lémanique " which was covered very quickly by sumptous hotel construction. But the mountain, very close, attracted also the high society of the " Belle Epque " who wanted to be able to go there easily. To do that, appropriate means of communication were needed. By the end of the 19th century, a concession was given for a railroad line " Montreux-Oberland Bernois ". By 1901, this railroad track went up to the village " Les Avants-sur-Montreux " (978 meters high) then with service to all the inter-mountain valleys. The arrival of that train in the villages – for the important movement of tourists it created – elevated them to a well-known status as compared to Gstaad, and made fashionable for " High Society " of the time. A region was born, that of M. O. B. Growing each year without ceasing. From then on, consideration of that region was necessary for successful tourism. Finally, regardless of the chagres in tourism, the company M. O. B. Can find solutions, by adapting itself to the needs of this regional entity on one hand, but on the other hand, by extending skillfully their area of influence to the Riviera Lémanique

Full textFor the longest time, Napoleon was the centerpiece of studies concerning the Napoleonic age. However, over the past thirty years, several important studies about the Consulate and the Empire have been shedding a new light on the socio-political history of this era. In this thesis, we review the administrative and centralizing structure established during the Napoleonic era, which represents a key period to discuss and observe the issues about the onset of the Nation-State. In the first part, The Nation-State and the notables, the reality of the local power established during the Napoleonic age is discussed. Initially, we explain the sociology of the local administrators and notables who compose the local power, then we analyse the relations between these notables and the prefectural administration by clearly defining the effective functioning of the councils instituted in each local administrative ward, and of the communal municipalities. In the second part, The Nation-State and the local order, we approach several administrative domains concerning the “security”, matters during the onset of the Nation-State. This thesis will set to define how these administrative domains have led to a three tier exerted power, central power, local power and people, which in turn constructed and gave birth to the local government system under the Napoleonic regime. To answer these questions, we choose the Hautes-Pyrenees department. Indeed, to relativize the territorial evidence of France geographically and psychologically, the border area of the Pyrenees is an interesting case for our study

Full textIn order to fulfil the roadmap for the development of telecommunication and information technologies (TIC), low noise level and very fast semiconductor devices are required. Heterojunction bipolar transistor has demonstrated excellent high frequency performances and becomes a candidate to address TIC roadmap. This work deals with experimental analysis and high frequency noise modelling of Si/SiGe:C HBT (STMicroelectronics tech.) and InP/InGaAs HBT (III-V Lab Alcatel-Thales).Chapter I introduces the basic concepts of HBTs operation and the characterization at high-frequency. This chapter summarizes the high frequency performances of many state-of-the-art HBT technologies. The first part of chapter II describes the two HBT sets, with paying attention on the impact of the base composition (SiGe:C) or the lateral reduction of the device (InGaAs) on static and dynamic performances. Based on TCAD modelling, the second part shows that a 15-25% germanium composition profile in the base is able to reach highest dynamic performances. Chapter III summarizes the static and dynamic results at low temperature, giving a separation of the intrinsic transit times and charging times involved into the performance limitation. Chapter IV presents noise measurements and the derivation of high frequency noise analytical models. These models highlight the impact of the current crowding and the self-heating effects, and the influence of the base-emitter heterojunction on the high frequency noise. According to these models the high frequency noise performances are estimated at low temperature for both HBT technologies

Full textPerforming an exoplanet direct detection means being able to image an object as faint as an extra-solar planet very close to its parent star. After compensation of the turbulence by the XAO loop and most of the star light removed by a coronagraph, the ultimate limitation of high contrast imaging systems lies in its quasi-static aberrations that creates a residual signal which limit the achievable contrast on the scientific detector. To increase the achievable contrast on the detector, these aberrations must be compensated for, ideally using focal plane data recorded from the scientific detector to avoid differential aberrations. The aim of this thesis was to develop a focal-plane wavefront sensor (WFS) dedicated to the estimation of quasi-static aberrations in high contrast imaging systems. This WFS, called COFFEE, estimates the aberrations both upstream and downstream of the coronagraph using coronagraphic focal plane images that differ from a known diversity aberrations introduced upstream of the coronagraph. During this research work, COFFEE has been developed, tested using numerical simulations and demonstrated on an in-house bench. Considering the limitations of the estimation accuracy, COFFEE's formalism has then been modified to allow it to estimate high frequencies aberrations with nanometric precision. This extended version of COFFEE has been successfully used on SPHERE to optimize the contrast on the scientific detector of the instrument using COFFEE in a dedicated compensation process. Lastly, a new compensation method has been developed in order to reach very high contrast levels on the scientific detector

Full textBlast furnace slags are a co-product of the metallurgical industry, used in composite cements (CEM II & III) as a partial substitution for Portland clinker and recognized in particular for their advantages in terms of lowering the heat of hydration, increased durability performance and reduced carbon footprint of concrete. Although achieving ultimate mechanical performance comparable to or better than Portland cement (CEM I), binders offering high levels of slag see the development of their mechanical strength greatly slowed down. This phenomenon is explained by a lower reactivity of the slag which requires "activation" conditions to react properly. There are various additives that accelerate the hardening of cements, among which calcium chloride shows the best performance. The effects of calcium chloride are particularly important during the first days of hydration. However, their use is strongly regulated because of the corrosive effect of chlorine on steels of reinforced concrete. The objectives of the thesis are to study the mechanisms of action of calcium chloride on cement-slag binders during the first days of hydration. A panel of experimental techniques has been used to specifically identify the action of chlorides on slag and cement. Coupled results from XRD-NMR SEM experiments show that calcium chloride causes an accelerated precipitation of portlandite and ettringite, resulting from the increase in the reaction rate of clinker. The start of the slag reaction takes place after about 12 hours, and is not impacted by the calcium chloride. On the other hand, the reaction rate of the slag increases in the presence of the accelerator. The rapid, significant and exclusive formation of Friedel salts in the presence of chloride is observed, replacing sulphated and / or carbonated AFm. Increasing the reaction rate of the anhydrous phases results in the precipitation of additional C-S-H. This formation of Friedel salts and C-S-H causes a faster filling of the porosity and the increase of the mechanical performances
