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.
