<p>This paper presents an overview of the present state of construction of cofferdam techniques with special emphasis and a brief on other techniques developed world over for mitigating hydraulic forces on the temporary structures. A cofferdam is a temporary ...

<p>Ottawa sand specimens premixed with 0, 3, and 5% bentonite by dry mass of sand were tested under undrained static and cyclic loading to investigate the effects of bentonite on the static and cyclic shear strength of the sand. The results show that allowing ...

Based on mineralogical and technological investigations of the deposit “Greda” important characteristics of bentonite clay were determined. Representative samples of the deposit were characterized with X-ray diffraction, low-temperature nitrogen adsorption, ...

During the past decades comprehensive investigations have been made on bentonite clays in order to find optimal components of the multi-barrier system of repositories for radioactive waste. The present study gives a mineralogical characterisation of some selected ...

<p>This paper evaluates the suitability of some smectite-rich samples from northern Patagonia (Argentina) for pharmaceutical use. The clays must comply with some general features before considering their use in pharmacy, including high mineral and chemical ...

<p>The outcomes of this study can provide insight into the swelling and the compressibility behavior of soil - bentonite mixtures, between non-swelling materials and swelling materials. A simple swell and compression laboratory test has been conducted for ...

The backfill for a borehole instrument is often an item that receives a disproportionate lack of attention. The behavior of the backfill, the material that is in the most intimate contact with both the formation and the instrument, is critical for obtaining ...

Diagenetic illitic clays from seven North American bentonites of Ordovician, Devonian, and Cretaceous ages and from three subsurface North Sea sandstones of Permian and Jurassic ages have been examined by X-ray diffraction (XRD) and transmission and scanning ...

Industry uses bentonite for its inherent physical properties, or for the physical properties it can develop in another material or product. A thorough understanding of the chemistry and structure of bentonite, or more appropriately montmorillonite, ...
