Characterisation of the multi-scale fabric features of high plasticity clays
(Institution of Civil Engineers (ICE), 2019-12)
Article
Accés obertAn investigation of the microstructural features of a high-plasticity clay, in both its natural conditions and reconstituted in the laboratory, is described. Scanning electron microscopy is used here to characterise the ... -
Compacted soil behaviour: initial state, structure and constitutive modelling
(Thomas Telford, 2013-05)
Article
Accés obertThe paper explores the behaviour of compacted soils throughout the (dry density–water content) compaction plane by means of a conceptual framework that incorporates microstructural information. The engineering properties ... -
Hydromechanical behaviour of a heterogeneous compacted soil: experimental observations and modelling
(2011-03)
Article
Accés obertThe paper describes a theoretical and experimental study of the coupled hydromechanical behaviour of a compacted mixture of bentonite powder and bentonite pellets intended as sealing material in underground repositories ... -
Mechanical behaviour of heavily compacted bentonite under high suction changes
(Institution of Civil Engineers (http://www.ice.org.uk/), 2003)
Article
Accés obertThe paper reports the results of an experimental study carried out on a bentonite compacted to a dry density of up to 1·7 Mg=m3, a high value for this type of soil. The soil fabric has been studied using a variety of ... -
Secondary compression of clays as a local dehydration process
(Institution of Civil Engineers (http://www.ice.org.uk/), 2001)
Article
Accés obertLong-term volumetric deformations of clays are interpreted in terms of water transfer from clay aggregates to the bulk water. Chemical potentials for the two states of water are first derived and then integrated into balance ... -
The mechanical properties of a high plasticity expansive clay
(2022-06)
Article
Accés obertThe mechanical properties of a high plasticity expansive clay from South Africa are reported. The experimental programme considered wetting after loading tests followed by one-dimensional consolidation and unloading of ...
