However, in commercial and industrial applications, the term bentonite is used more generally to refer to any swelling clay composed mostly of smectite clay minerals, which includes montmorillonite. Bentonite usually forms from the weathering of volcanic ash in seawater, or by hydrothermal circulation through the porosity of volcanic ash beds,[3][4] which converts (devitrification) the volcanic glass (obsidian, rhyolite, dacite) present in the ash into clay minerals. They are also used for clarifying wine, liquor, cider, beer, mead, and vinegar. In geology, the term bentonite is applied to a type of claystone (a clay rock, not a clay mineral) composed mostly of montmorillonite (a clay mineral from the smectite group).

Bentonite is one of the most important materials used in constructing plastic concrete which act as a stabilizing agent. Uses of Bentonite in Construction Overlap and stagger seams at least 4 (101.6 mm). This accounts for the swelling property of montmorillonite and other smectite clay minerals.[6]. This means that a crystal of montmorillonite consists of layers, each of which is made up of two T sheets bonded to either side of an O sheet. As the name suggest, they are constructed by mixing a bentonite slurry with the excavated soil (USEPA, 1998; Van Deuren et al., 2002). Cleaning to remove suspended detritus, by passing through screens and hydro cyclones, in preparation for re-use.

Bentonite is not stable when it is diluted by water. Bentonite support fluids have been used for the construction of diaphragm walls and bored piles since the pioneering work of Veder (1953).It is now known that in permeable soils such as sand and gravel, the stabilising mechanism involves the formation of a filter cake on the side walls. [38][39], Bentonite application also influenced the prices that farmers received for their crops. It can be directly mixed with cement (dry-blended) and later the blend is mixed with water/mix water/mix fluid or it can be mixed in the mix water (pre-hydrated) and later cement is added in the mixed fluid.
