The understanding of the structural formula of smectite minerals is basic to predicting their
physicochemical properties, which depend on the location of the cation substitutions within …

A review and a synthesis of the geological, mineralogical, and crystal chemical data
available in the literature on active Spanish bentonitic exploitations were done, and at the …

The effect of pH on the kinetics of smectite (K-montmorillonite) dissolution was investigated
at 25° C in batch and stirred flow-through reactors over the pH range of 1–13.5, in KNO3 …

The mineralogy, geochemistry and physical and physicochemical properties of three
Spanish clays and their mixtures with distilled water were determined. These results were …

Clays have been used by man since prehistoric times. Initially they were used almost
exclusively in the fabrication of ceramics; nowadays they find numerous industrial and …

Concrete and bentonite are being considered as engineered barriers for the deep
geological disposal of high-level radioactive waste in argillaceous rocks. Three …

Bentonites are used in deep geological disposal facilities as an engineered barrier to isolate
high level radioactive waste, contained in metallic canisters. The present study, performed at …

Red-coloured clay-rich beds (bole beds) occur at flow breaks in parts of the Deccan volcanic
province (DVP). These boles in the Deccan province retain paleoenvironmental information …

Compliance of concrete–bentonite barriers is a key issue in the performance assessment of
long-term underground storage of radioactive waste. The reaction of synthetic alkaline …

The in situ FEBEX experiment performed at the URL in Grimsel (Swizerland) was dismantled
after 18 years of operation. Interface samples between bentonite and a shotcreted concrete …
