The Use of Clay as an Engineered Barrier in Radioactive-Waste Management a Review

Patrik Sellin, +1 more
- 01 Dec 2013 - 
TL;DR: Bentonite and bentonite/sand mixtures are selected primarily because of their low hydraulic permeability in a saturated state, which ensures that diffusion will be the dominant transport mechanism in the barrier as mentioned in this paper.

The relationship between suction and swelling properties in a heavily compacted unsaturated clay

Pierre Delage, +2 more
- 01 Sep 1998 - 
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.

María Victoria Villar, +1 more
- 01 Aug 2004 - 
TL;DR: In this article, the influence of temperature (between 20 and 80 °C) on some hydro-mechanical properties of a compacted bentonite has been investigated, showing that the water retention capacity at higher temperature, both in confined and unconfined conditions, is lower.
