Experiment evidence on the temperature dependence of desiccation cracking behavior of clayey soils
TL;DR: In this article, the authors investigated the desiccation cracking behavior at three temperatures (22, 60 and 105°C) and found that the initial critical water content (wIC), which corresponds to the initiation of desiliccation crack, increases with temperature rise, and the ratio RSC increases with decreasing water content and then keeps almost constant when the water content becomes lower than the critical Water Content (wFC).

Experimental study on the swelling behaviour of bentonite/claystone mixture
TL;DR: In this paper, a mixture of the MX80 bentonite and the Callovo-Oxfordian (COx) claystone was investigated by carrying out a series of experiments including determination of the swelling pressure of compacted samples by constant volume method, pre-swell method, zero swell method and swell-consolidation method.

A study on the thermal conductivity of compacted bentonites
TL;DR: In this paper, a thermal probe based on the hot wire method was used to measure the thermal conductivity of compacted bentonite specimens and the experimental results were analyzed to observe the effects of various factors (i.e. dry density, water content, hysteresis, degree of saturation and volumetric fraction of soil constituents).

The relationship between suction and swelling properties in a heavily compacted unsaturated clay
TL;DR: In this article, the water retention and swelling properties of the FoCa7 clay under controlled suction and zero applied stress were examined. But the results of the experiments were limited to the case of very high suction.

Determination of Surface Area of Fine-Grained Soils by the Ethylene Glycol Monoethyl Ether (EGME) Method
Amy B. Cerato,Alan J. Lutenegger +1 more
TL;DR: In this paper, the authors describe a test procedure for determining the total surface area of fine-grained soils using the Ethylene Glycol Monoethyl Ether (EGME). The test involves saturating a soil sample with EGME and then removing the excess EGME in a vacuum desiccator, until the EGME forms a monomolecular layer on the soil surface.
