???? ????? ????? ????? ????Index. décimale : 626 Génie Climatique Résumé : To reduce energy consumption in construction field and environmental problems involved in the industrial and domestic waste recycling, a reinforced concrete with polystyrene chips starts to be used in recent years. However, one records a lack of knowledge of his thermo-hydrous characteristics. The objective is to develop and validate a predictive model of hygrothermal behavior of a multilayered wall composed of this material and cement mortar. The study involves two aspects: a first aspect is to study the hygrothermal behavior of polystyrene concrete and cement plaster subjected to external excitations. Numerical and experimental approaches are used. For both approaches, the ambient conditions have a direct impact on the behavior of the walls. Studies are therefore conducted in varying
climatic conditions on blocks. In parallel to the experimental approach, a model representative of heat and mass transfer in materials: capillaro-porous media (composite concrete) and multiphasic media (plaster), is developed in order to predict hygrothermal behavior of the wall. This model is validated by confrontation of simulated and experimental responses. A second aspect is to characterize these highly heterogeneous materials.Diplôme : Doctorat en sciences En ligne : ../theses/gclim/CHI6979.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10377 Etude du comportement thermo-hydrique des parois des bâtiments. : Influence des effets de l’etat hygrothermique et des propriétés thermo-physiques [texte imprimé] / Ali Chikhi, Auteur ; Azeddine Belhamri, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2016 . - 157 f. ; 30 cm.

?????? ??????? ? ?????? -??????? ????????- ???? ????- ???? ????? ???????-?????? ?????????- ???? ???? ??????.Index. décimale : 624 Génie civil Résumé : "The present study concerns coupled mass and thermal transfers in tow simple and
multilayered walls, by using constant and variable boundary conditions.
The thermal mechanism transfer is presumed by conduction and that of mass is assumed by
diffusion. We have adopted thermal conductivity and mass diffusivity which are variable and are
functions of water content. Temperature, moisture content, thermal and mass flux continuity is
used at the level of layer contact surfaces for multilayered wall.
To better know the influence of the variation of the outside conditions on the behavior of the
thermal transfer and the evolution of the temperature in the wall. We have adopted external
boundary conditions as periodic and sinusoidal form. In order to be much closer from reality, we
have studied the transfers in a simple wall made of concrete and in another one which is
multilayered.
Basing on finite volumes method, some simulations have been realized, using a code of
calculation by Fortran 90. The results are validated by comparing them with other studies
recently published. They show that:
- The transfer coefficients are strongly coupled, and the physical medium
characteristics make the thermal transfer unsteady.
- The boundary conditions strongly influence the evolution of the temperature in the
wall and also the thermal flux densities at the level of wall interior surface."
