“…However, its initial water content is usually not the same as that of the clay matrix in sand-clay mixtures. It is well recognized that the compression behavior of remolded clays is affected by the initial water content (e.g., Cerato and Lutenegger, 2004;Hong et al, 2010;Shi and Herle, 2015;Zeng et al, 2015;Zeng et al, 2016;Tsuchida, 2017). Hence, the void ratio of the clay matrix in a mixture (with the same sand fraction but different initial water content of the clay matrix) should be different at a given stress level, which would affect the overall hydraulic conductivity.…”

A series of oedometer tests was performed on a pure marine clay and sand-marine clay mixtures with various initial water contents of the clay matrix and sand fractions. The hydraulic conductivity was computed from the compressibility and the consolidation curves of the samples. The experimental data indicate that the overall hydraulic conductivity of the mixtures depends on both the initial water content and sand fraction of the clay matrix at a given stress level. The initial water content of the clay matrix has an influence on the local void ratio, leading to differences in the overall hydraulic conductivity. The influence of the initial water content is substantially reduced in case of the relationship between the overall hydraulic conductivity and the overall void ratio. A homogenization approach is introduced in this paper to estimate the overall hydraulic conductivity which can be determined from the intrinsic permeability parameters of the pure marine clay. The proposed model has four parameters, including two intrinsic parameters of the pure marine clay and two additional ones incorporating the evolution of sand skeleton. The ability of the proposed model to describe the permeability behavior of the sand-marine clay mixtures (and other sand-clay mixtures from literature) is verified by using test data.

“…Recent publications revealed that the NCL of a clay is not unique, which is affected by the initial water content (Cerato and Lutenegger, 2004;Hong et al, 2010;Liu et al, 2013;Shi and Herle, 2015;Tsuchida, 2017;Zeng et al, 2015;Horpibulsuk et al, 2016;Zeng et al, 2016a and. Consequently, the compression curves of sand-clay mixtures with different initial water contents of the clay matrix are not comparable.…”
