Anisotropic swelling pressures of compacted GMZ bentonite …

To reach the required value of 2 MPa (Posiva, 2017), the initial compacted dry density of bentonite must exceed 1.55 Mg/m 3 at an approximate underground water concentration of 0.1 mol/L based on the underground water chemical environment (He, 2017; Sun et al., 2018). The designed value of dry density should be further enhanced …

Geotechnical properties and applicability of bentonite …

The high swelling potential of bentonite, which creates a gel surrounding the soil grains, increases their effective size and raises the void ratio, which lowers the dry density as a result (Kumar and Yong, 2002b; Lambe, 1958b). Again, 5%, 10%, 15%, and 20% added bentonite with the soil increased the optimum moisture content of the …

Investigation of the emplacement dry density of granulated bentonite …

Bentonite is a clay material consisting mostly of montmorillonite. Bentonite-based buffer materials of the EBS will saturate over time with groundwater from the host rock. This results in a swelling pressure, a decrease in hydraulic conductivity and an increase in thermal conductivity (e.g., Ref. 3).

The plastic behavior and compression of bentonite clay …

Compacted bentonite is generally proposed as a buffer material as it is characterized by low permeability and high swell capacity. It is normally placed in layers in a partially saturated condition with a dry density in the range of 1.4–1.7 g/cm 3 [5].

Comparative study of hydro-mechanical behaviors of compacted bentonite

As dry density increases to 1.95 Mg/m 3, the curve of CBP exhibits an unimodal porosity shape, indicating the disappearance of inter-aggregate pores. Consequently, the high dry density of bentonite pellets, as a basic unit of GB, leads to a dominance of intra-aggregate pores. Compared to CBP, GB has larger inter-pellet pores.

About differences of swelling pressure — dry density relations …

A mesoporous bentonite is supposed to possess high density domains (next to the uncompactable porosity) which can exert much more swelling pressure than others despite the same dry density. Varying the water content a maximum of the dry density depending on the water content is observed (constant compaction). This means that one …
