      Bentonite Properties/ Specification Bentonite is an industrial rock which is occurred naturally, identified by the feature of waterabsorbing and by the capacity for Base Exchange; both features are considerably greater than that of kaolin and plastic clays In some bentonites, water absorption is supplemented by a significant increase in volume,   GENERAL STATEMENT The properties of bentonites are contingent upon the fact that they are composed of smectite clay minerals, and the properties of the smectite in turn are contingent upon its chemical composition, atomic structure, and morphologyChapter 5 Properties and Uses of Bentonite The special properties of bentonite (hydration, swelling, water absorption, viscosity, thixotropy) make it a valuable material for a wide range of uses and applications Bentonite deposits are normally exploited by quarrying Extracted bentonite is distinctly solid, even with a moisture content of approximately 30%What is Bentonite?

    Bentonite is a natural occurrence material dominantly the Clay Mineral Montmorillonite It is having a layered structure that possesses High Swelling properties and High Cation exchange capacities When in contact with water it expands up to Twenty to Forty times its dry volume  Swelling of bentonite material interacting with water is considered as a main property ensuring the containment function by filling the voids (self sealing) inside the installed barrier resulting in a homogeneous medium even if elements of a differ ent shape are used (blocks, pellets, granules, etc) (Figure 2) Swelling pressure of compacted bentonite basi cally depends on the matrix density and BUFFER PROPERTIES OF BENTONITE BARRIER SYSTEMS   31 Properties of Bentonite 15 32 Properties of Sand 17 main advantage in using bentonitesand mixtures is low permeability due to highly swelling nature of bentonite The bentonite particles swell and fill the voids present in between theAn Experimental Study on Engineering Properties of
