Résumé
The need to reduce the energy for heating and cooling is leading to a renewal of interest in geo-sourced materials for modern building construction. These materials offer many advantages in terms of climate change adaptation, and reduction of CO2 emissions from building materials. This study presents the characterization of clay, fiber, and hygrothermal characterization of two types of clay mixtures reinforced with natural vegetable fiber for use in modern construction. Cob is a mixture of clay, water, and vegetable fibers. It is non-load bearing and serves as a filler for the wood frame. The wall design is suited for lightly seismic zones. Cob has great potential for applications in places with high housing and cooling needs. The hygrothermal properties of 30 clay formulations containing 0%, 3%, and 6 wt% wheat fibers were evaluated. At this fiber content, the material is considered a heavy type of cob. The measured thermal and hydric properties of the clay-fiber mixture presented in this paper are thermal conductivity, thermal effusivity and diffusivity, specific heat, water absorption, water vapor permeability, moisture buffer value (MBV), and sorption/desorption isotherms. Wheat fibers used in clay material mixtures improve their hygrothermal properties for sustainable construction. These results allow the development of a model hygrothermal model of wall elements.
