Última Interpretation of the stiffness and permeability of Sand-Kaolin mixtures in the framework of homogenization Anais da ABC (AABC) Boutin,Claude; Kacprzak,Gregory; Doanh,Thiep. This study deals with the behaviour of mixtures of sand and saturated kaolin paste considered as composite materials made of permeable and deformable (with non-linear behaviour) matrix (the kaolin paste) with rigid and impervious inclusions (the sand grains). Oedometric and permeability tests conducted on such mixtures highlight the key role of the state of the clay paste, and show the existence of a threshold of sand grain concentration above which a structuring effect influences both modulus and permeability. At the light of these experiments, the usual and tangent homogenization process (with simplifying assumptions to make the problem manageable) has been applied to estimate the mixture permeability and tangent compressibility. Qualitative and... Tipo: Info:eu-repo/semantics/article Palavras-chave: Homogenization; Non-linear behaviour; Sand-clay mixtures; Permeability; Tangent modulus; Compaction; Hardening.
