Étude du gel/dégel de surface des murs d’habitations en terre crue

Abstract : Nowadays, earthen construction is gaining more interest because of its low environmental impact and its thermo-hygro-mechanical performances. Nevertheless, the problem of water durability and the lack of standardized protocols are limiting the development of this mode of construction. In cold regions, the observation of frost damage (scaling and cracking) also presents frost resistance as a major development issue for earthen constructions. On the one hand, the physical mechanisms related to frost generate a strong coupling and additional complexity. On the other hand, due to the severity of the standard freezing protocols for concrete, their application to the earth material is not acceptable. This paper aims to propose an experimental protocol better adapted to the reproduction of the freezing conditions of earthen constructions. For this, the work starts from a modification of the experimental method of the freezing-thawing of stabilized and compacted soils to consider the effect of frost, capillary rise, stabilization and compaction. An analysis of the variations in water content, geometric deformations and mass losses allow us to conclude on the validity of the experimental approach proposed.
