For the safe disposal of high-level radioactive waste using Engineered Barrier Systems
(EBS), bentonite buffer is used by its high swelling capability and low hydraulic conductivity …

Nanoporous media consist of homogeneous or heterogeneous porous material in which a
significant part of the pore size distribution lies in the nanometer range. Clayey rocks …

Hydraulic fracturing is typically required before shale gas production. Residual fracturing
fluid in the reservoir leads to a hydration reaction and weakens the fracturing effect. To …

Sufficient swelling pressure of compacted bentonite upon wetting is necessary to provide
long-term stability to an engineered barrier system under conditions of thermal gradient and …

This paper investigates the volumetric, microstructural, and shear behaviours of an
expansive soil during multiple drying-wetting (DW), freeze–thaw (FT), and drying-wetting …

This paper investigates the evolution of the soil-water characteristic curve (moisture content-
suction relationships, SWCC), soil shrinkage characteristic curve (moisture content-void ratio …

Water is the most abundant molecule found on the earth's surface and is a key factor in
multiscale rock destruction. However, given the fine-grained nature of rock and the …

Bentonite pellet/powder mixtures have been proposed as the candidate sealing plugs of
boreholes or galleries in deep geological disposal of high-level radioactive waste. During …

Some deep geological nuclear waste disposal concepts are considering the installation
around the waste canisters of bentonite barriers made up of two components: highly …

During the long-term evolution process of the geological repository, the gas permeability
evolution of the buffer material is critical to its sealing performance evaluation. The purpose …
