Mercado, Mendoza Hugo Ramiro. "Transferts aqueux à travers les matériaux cimentaires partiellement saturés." Toulouse 3, 2012. http://thesesups.ups-tlse.fr/1722/.
Full textThe diffusivity properties are of great importance as far as the durability of a construction made of cement-based materials, such as a particular solution for radioactive waste disposal, is concerned. Besides, the influence of material microstructure on transfer properties is recognized and ensues both from the characteristics of the material itself as well as from its history and environment conditions. In service conditions, cement-based materials are seldom at a fully saturated state. The scientific community has long since ascertained the lack of experimental data on aqueous diffusion in non-saturated medium. The main purpose of this work is to determine de diffusion coefficient of an ionic species through partially saturated cement-based materials. An approach has been proposed on the basis of the analogy between ionic diffusion and electrical conductivity - given by the Nernst-Einstein relationship - and the formation factor concept. Accordingly, an experimental programme based on the electrochemical impedance spectroscopy test, together with a data analysis procedure using an electrical model of material microstructure, have been developed. A first validation study has been carried out by means of an electrokinetic test on saturated materials. The geometric character of the formation factor, reflecting the pore network configuration whatever the pore solution ionic force or composition, has been shown. As a consequence, the diffusion coefficient of chloride ion has been calculated, highlighting the suitability of the proposed method. This method has allowed to determine the diffusion coefficient of an ionic species through several partially saturated materials. It has been observed that the formation factor depends also on the material saturation level. Thus, the diffusion coefficient turns out to be an intrinsic parameter of the material, through its pore network and its solution content. The shapes of evolution of the diffusion coefficient as a function of saturation level have shown the existence of leading paths for ionic species transfer through materials. In a logical way, these paths seem to be related to the main pore modes, but also to the total open porosity of the material

Full textDue to their low cost, lightness and thermal properties, lignocellulosic byproducts received a particular attention, in the recent years, for manufacturing lightweight concretes. However, these byproducts are not fully compatible with the cement matrix, leading to setting delay, significant dimensional variations, and low mechanical strengths of the composites elaborated. To avoid such drawbacks, a coating process of flax shives using different substances has been adopted in this study. It leads to a reduction in treated shive water absorption compared to raw shives. The composites obtained exhibit significant improvements in hydrous behavior and mechanical strengths with moderate increase in the apparent bulk density and thermal conductivity. The phenomena of moisture transfer in the produced composites can significantly influence the durability and performance of them. In fact most of the materials used in the building area are porous, containing water as vapor or liquid. Therefore the water vapour permeability, sorption isotherms and moisture buffering capacity have been determined. The results obtained show the good hygric performance of the eco-composites elaborated. Three leaching tests have been proposed in this study to identify the chemical speciation of the materials and to evaluate their releasing into the environment. The experimental conditions of the leaching tests have been chosen to simulate different states of our composites in external environments in service or end of life. The leaching behaviour of the cement-based products elaborated differs little according to flax shive treatment and the leaching of toxic substances has not been identified

Full textProperties of improved strain capacity and high shrinkage cracking resistance make rubberized cement-based composites suitable for large surface applications such as cement-based pavements and thin bonded overlays. However, bond defect between rubber aggregates (RA) and cement matrix is well-known and detrimental to properties of rubberized cement-based materials. It is universally accepted a reduction in some mechanical properties of rubberized cement-based composites mainly due to low stiffness of RA. Nevertheless, their transfer properties could indeed be competitive with control mortar (without RA) if bond at rubber-cement matrix interface is improved. In order to enhance the interface, RA were firstly coated with styrene-butadiene copolymer and after complete densification of this copolymer on surface of RA, they were mixed with the pre-mixed cementitious mixture. Microstructural analysis using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectrometry (EDS), and X-Ray Diffraction (XRD) clarified that cement paste bonded firmly on copolymer-coated RA. Mechanical and transfer properties of this mortar were then compared to that of control mortar and two rubberized mortars in which one of them air-detraining admixture was added to produce rubberized mixture with the similar air content as the control mortar. Findings have demonstrated an enhanced rubber-cement matrix interface provided a significant improvement on transfer properties such as air permeability and water capillary absorption. However, a reduction in mechanical properties (compressive strength and modulus of elasticity) was still observed due to low stiffness of RA. Rubber coating appeared to limit the reduction in tensile strength and to result in a higher residual post-peak strength and fracture energy, demonstrating an improved material bridging effect made possible by the bond between RA and cement matrix. The bridging effect also contributed to improve resistance of rubberized composites to shrinkage cracking even under high restrained conditions. Based on above-mentioned characteristics, the study further investigated the durability of rubberized mortars under aggressive environments to observe the effects of RA incorporation and of an enhanced rubber-cement matrix interface. Regarding acetic acid attack, a low degraded depth and a reduction in loss of both mass and compressive strength of rubberized mortars, especially the one incorporating copolymer-coated RA, were observed compared to the ones of the control mortar. The coated rubberized mortar also behaves better in preventing sodium sulfate diffusion into the composite. The degradation of mortars under aggressive environments was also evaluated based on a damage variable, which was defined as a relative change in equivalent load-resisting area of mortar specimens between their original condition and at a given time when they were exposed to acid or sulfate solutions. From damage variable values, it can be concluded that coated rubberized mortar was more durable than the untreated one against aggressive environments. The durability of untreated and coated rubberized mortars under freeze-thaw cycles was also carried out and compared to that of control mortar. The rubberized cement- based composites were more resistant to freezing and thawing than the control one, especially in terms of dimensional expansion. The better performance can be attributed to high energy absorption of RA and to higher porosity, lower water capillary absorption and high strain capacity of rubberized mortars. Rubber coating, even reducing the permeability of rubberized cement-based composites, still remained high durability of their applications under frost environment

Full textThe influence of the incorporation of a product organically sourced in cementitious materials (at fresh and hardened state) was studied. The presence of the bioproduct does not cause changes on mechanical strength and on cement past microstructure (TGA / DTA and XRD). Porous network characterization tests on mortar and cement paste showed an effect of bioproduct on the quality of skin samples. A protocol of realization and conservation of cement paste samples was developed in order to allow various tests on same surfaces for the microbiologists partners of the « extra cellular substances for concrete » project. The study of the evolution of the dynamic contact angle of a drop of water placed on cement pastes showed that the presence of the bioproduct favored at the expense of spreading the penetration of water within the material, modifying the tortuosity of the capillaries of the cementitious matrix. An analytical method of drop behaviour (contact angle versus diameter) was developed and validated with literature data. This original technique allowed an accurate determination of the angles of advance and retreat on porous substrates
