Modelling the thermo-mechanical volume change behaviour of compacted expansive clays

Author(s) : Tang, Anh-Minh , Cui, Yu-Jun
Description : Compacted expansive clays are often considered as a possible buffer material in high-level deep radioactive waste disposals. After the installation of waste canisters, the engineered clay barriers are subjected to thermo-hydro-mechanical actions in the form of water infiltration from the geological ...

A new isotropic cell for studying the thermo-mechanical behavior of unsaturated expansive clays

Author(s) : Tang, Anh-Minh , Cui, Yu-Jun , Barnel, Nathalie
Description : This paper presents a new suction-temperature controlled isotropic cell that can be used to study the thermo-mechanical behavior of unsaturated expansive clays. The vapor equilibrium technique is used to control the soil suction; the temperature of the cell is controlled using a thermostat bath. T...

Controlling suction by vapour equilibrium technique at different temperatures, application to the determination of the water retention properties of MX80 clay

Author(s) : Tang, Anh-Minh , Cui, Yu-Jun
Description : Problems related to unsaturated soils are frequently encountered in geotechnical or environmental engineering works. In most cases, for the purpose of simplicity, the problems are studied by considering the suction effects on volume change or shear strength under isothermal conditions. Under isoth...

Thermo-mechanical behaviour of a compacted swelling clay

Author(s) : Tang, Anh-Minh , Cui, Yu-Jun , Barnel, Nathalie
Description : Compacted unsaturated swelling clay is often considered as a possible buffer material for deep nuclear waste disposal. An isotropic cell permitting simultaneous control of suction, temperature and pressure was used to study the thermo-mechanical behaviour of this clay. Tests were performed at tota...

A study on the thermal conductivity of compacted bentonites

Author(s) : Tang, Anh-Minh , Cui, Yu-Jun , Le, Trung Tinh
Description : Thermal conductivity of compacted bentonite is one of the most important properties in the design of high-level radioactive waste repositories where this material is proposed for use as a buffer. In the work described here, a thermal probe based on the hot wire method was used to measure the therm...

Effects of the maximum soil aggregates size and cyclic wetting-drying on the stiffness of a lime-treated clayey soil

Author(s) : Tang, Anh-Minh , Vu, M.N. , Cui, Yu-Jun
Description : Lime treatment is a well-known technique to improve the mechanical response of clayey subgrades of road pavements or clayey soils used for embankment. Several studies show that lime treatment significantly modifies the physical and hydro-mechanical properties of compacted soils. Nevertheless, studie...

Monitoring field soil suction using a miniature tensiometer

Author(s) : Cui, Yu-Jun , Tang, Anh-Minh , Mantho, Altin Theodore , De Laure, Emmanuel
Description : An experimental device was developed to monitor the field soil suction using miniature tensiometer. This device consists of a double tube system that ensures a good contact between the tensiometer and the soil surface at the bottom of the testing borehole. This system also ensures the tensiometer pe...

Determining the unsaturated hydraulic conductivity of a compacted sand-bentonite mixture under constant volume and free-swell conditions

Author(s) : Cui, Yu-Jun , Tang, Anh-Minh , Loiseau, Cyril , Delage, Pierre
Description : Highly compacted sand-bentonite mixtures are often considered as possible engineered barriers in deep high-level radioactive waste disposals. In-situ, the saturation of these barriers from their initially unsaturated state is a complex hydro-mechanical coupled process in which temperature effects al...

Analysing the form of the confined uniaxial compression curve of various soils

Author(s) : Tang, Anh-Minh , Cui, Yu-Jun , Eslami, Javad , Défossez, Pauline
Description : The soil compaction by vehicles is a major factor responsible for physical degradation of cultivated soils. Uniaxial confined compression tests are usually performed to characterise the compaction properties of soil. Two main forms of compression curve have been observed: (i) the bi-linear curve hav...
