That supposes a reliable and relevant estimate strength and deformation properties of the grounds, for obtaining the suitable values of the parameters characterizing the rupture, of many research as well theoretical as experimental are offered.
The experimental way was largely explored during last decades and it was the subject of our study.
On the experimental level, the testing methods most frequently used for the validation of the models of behavior comprise primarily oedometric tests compression and shear tests to the traditional triaxial apparatus.
These tests constitute the basic tools for the knowledge of the behavior of clays and make it possible to follow ways of constraints or deformations simulating the real behavior of the works in place. In parallel, of the testing methods in situ (penetrometers, pressiometers, etc.) were developed in order to characterize the best possible behavior of clays in place. Although these tests have the advantage of being inexpensive and rapids to be carried out, of or their relative success, the results obtained difficult with is interpreted in term of laws of behavior of the grounds, because the ways of total or effective constraints follow-ups in these tests are badly known, the boundary conditions space are impossible to define, the conditions of drainage or are not known generally little, etc. These difficulties pose serious problems with the good in situ test schedule –and their exploitation, which allowed privileged people the laboratory, tests (oedometers, triaxial).
The objective of this study is the experimental characterization of the model of behavior of natural clays several sites of the area of Constantine, the test routine A made it possible to determine the form of the surface of load, which is controlled by the constraint of preconsolidation, it has an appreciably elliptic form inclined on the line µ O or Ko On the level of the laboratory tests we had interesting results concerning the strength parameters it and φ ', the param beings of deformations and the coefficient of earth pressure at rest Ko.
These results are comparable with those obtained on other natural clays which have the same behavior and the same shape of the curve of absolute limit (Jausseaume, Azizi, 1991), the clay of Guiche (valley of Adour) (khemissa, J-P.Magnan, H.Josseaume), the clay of Saint-Alban (Leroueil and Al, 1979).Diplôme : Doctorat en sciences En ligne : ../theses/gcivil/BEL5886.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=5669 Caractérisation des formations argileuses de la région de Constantine.

Génie CivilTags : Hétérostructures Impédances Permittivité Index. décimale : 624 Génie civil Résumé : This work deals with the characterisation of heterostructures by two nondestructive methods: (1) the equivalent electrical impedance method for systems of simple geometry; and (2) the method of the effective complex permittivity for systems of complicated geometry. The simulated results obtained
using each one of both methods are experimentally validated. In the first case. The relationships of the equivalent impedance are analytically determined for various heterostructures , and mixture laws giving the effective dielectric permittivity and resistivity are also deduced in function of the concentration of inclusions and both the permittivity and resistivity of each component of the heterostructure. To illustrate this method, experimental validations are achieved on sandwich structures and on samples containing identical aligned inclusions, in the form of square section
tubes, embedded in a polymer matrix and which are filled either by air or water. In the second case, the effective complex permittivity is computed by a numerical approach based on the boundary integral equation method (BIEM) and the PHI3D package. The considered. Heterostructure consisting of a host material and inclusions periodically distributed. It’s also shown that this method enables to
predict the presence of inclusions and their concentration in a given heterostructure. Experimental validations, carried out on samples composed of cylindrical cavities, filled either by water or air, embedded in a polymer matrix, are also presented.Diplôme : Doctorat En ligne : ../theses/gcivil/BER5319.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=623 Caractérisation des hétérostructures par la methode des impédances et par la permittivité diélectrique effective complexe [texte imprimé] / Ahmed Beroual ; Univ. de Constantine, Éditeur scientifique ; Hacene Houari, Directeur de thèse . - 2006 . - 125 f.

Génie CivilTags : G.civil:Matériaux de construction Cinétique hydratation Index. décimale : 624 Génie civil Résumé : Predicting the short-term strength of concrete is essential in the field of civil engineering. To meet some building requirements (quick formwork removal, earlier prestressing, concreting in cold weather …), it is necessary to make concrete that has the best possible mechanical strength at a young age. The development of this type of concrete requires generally the use of admixtures associated with pozzolanic mineral additions such as silica fume. However this by-product, from the silicon and silica-ferrites alloys industry, still has a high cost owing to its limited production in the industrialised countries and non-availability in the others countries.
In this research work, we propose others substitutes to silica fume and the use of special substitution techniques. In addition, combinations of setting and hardening accelerators are considered so as to improve both setting and hardening concrete time as well as the mechanical strength at early age.
The results obtained show that the use of alkanolamine combined with calcium nitrate in cement mixes containing siliceous sand grinded and homogenised with cement produced a significant improvement in the mechanical strength at all stages particularly in the early ages (1 and 3 days) and also provided an important reduction in the setting time. Our results indicate that these performances are also dependant on the type of cement used mainly its alumino-ferrites composition.
