The increase in the as-compacted degree of saturation in loose samples (dry density ≤1·3 Mg/m3) produces an enhancement in the proportion of macro pores, thus increasing keff, as a consequence of modifications in the pore size distribution. A threshold value has been identified, above which further increase in degree of saturation causes a reduction in the proportion of macro pores, and therefore in keff. A new proposal for estimating the air permeability is proposed in this paper based on the determination of a pore size parameter obtained from MIP data. The proposed approach seems capable of describing the evolution of air permeability for the whole spectrum of compaction states, including specimens subjected to wetting and drying paths.]]> Wed 10 Aug 2022 13:37:24 AEST ]]> The competing effects of wetting and volume change on G0 in compacted loess https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54229 Tue 13 Feb 2024 12:17:52 AEDT ]]> Microstructural effects on the wetting-induced collapse in compacted loess https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48675 Mon 27 Mar 2023 14:18:55 AEDT ]]> Environmental degradation of clayey rocks https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44848 Mon 24 Oct 2022 10:48:40 AEDT ]]> Osmotic effects on the microstructure of Ashfield shale https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44847 Mon 24 Oct 2022 10:48:33 AEDT ]]> From saturated to unsaturated conditions and vice versa https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36212 Fri 06 Mar 2020 12:36:42 AEDT ]]>
