Commodity Description. Bentonite is a type of clay rock that is widely used in industrial processes and products and in consumer products. When wetted it holds water and swells significantly and, upon drying, it shrinks significantly. When mixed with sufficient water to create a slurry it forms materials that become more solid when compressed.
bentonite layers are charged due to exhange of Al(III) with for example Mg(II) and/or Fe(II) yielding an excess of negative charges. To obtain electroneutrality bentonite clay holds, most commonly, sodium or calcium ions as counterions. This lamellar structure should make bentonite clay a perfect model system for an electrical

Moreover, although bentonite retained the original lamellar structure in the hydrated cement mortar, hydration products (such as needle-like and amorphous C-S-H or C-S-A-H and others) were found in the surface or edge of the bentonite according to EDX results (Fig. 4), which was consistent with Jiang's research findings [42]. The surface or ...

The natural bentonite was purified in the laboratory to remove calcite, carbonates, and organic matters by the following protocol: the sample was first repeatedly washed with Milli-Q water and dried after each time. The dried bentonite clay (25 g) was soaked in 400 mL solution containing Na-Ac (0.1 N) and Ac-Ac adjusted to pH ≈ 5.0.
