Hydro-mechanical properties of a water unsaturated sodium bentonite. Laboratory study and theoretical interpretation
Highly compacted bentonite has been proposed as the buffer material in the Swedish concept for the disposal of nuclear waste. To increase the knowledge of the hydro-mechanical behaviour of unsaturated swelling bentonite a series of laboratory experiments was carried out. The main purpose was to conceptually model the hydro-mechanical behaviour of the bentonite. The influence of testing techniques
