Abstract Knowledge of the behavior of highly compacted expansive clays, as an engineered
barrier, in disposal of high-level nuclear waste (HLW) systems to prevent the pollution due to …

The potential for microbial activity to occur within the engineered barrier system (EBS) of a
geological disposal facility (GDF) for radioactive waste is acknowledged by waste …

The type of soil known as expansive soil is capable of changing its volume through swelling
and contracting. These types of soils are mostly composed of montmorillonite, a mineral with …

A specific oedometer cell has been set up to measure the swelling pressure of compacted
montmorillonites at constant volume and to concomitantly visualise the evolution, upon …

Gaomiaozi (GMZ) bentonite is a potential buffer/backfill material for a deep geological
disposal of high-level radioactive waste. It has a wide pore size distribution (PSD) with sizes …

One of today's big challenges is to store safely the increasing amount of high-level
radioactive waste (HLRW) in the world. In some of the concepts devised for this challenge …

Several large-scale mud and water inrush events occurred during excavation of the
Denghuazhai Tunnel at a depth of 175 m in the contact zone between geodic granite and …

Bentonite and bentonite mixtures are used as buffer material for deep geological radioactive
waste repositories. The proper determination of bentonite maximum swelling pressure is …

The swelling pressure of montmorillonite is an important factor in designing the bentonite
buffer for geo-disposal of nuclear waste. A method to predict the swelling pressure of …

Volcanic tuffs and sandstones have been used as natural building stones in the construction
of monuments and buildings over the millennia of human history. Progressive weathering …
