Print this pageBentonite is the name used for a range of clays that can swell and gel when dispersed in water. It is now used extensively in civil engineering but it is important to recognise that the properties of bentonite from different sources vary. These variations must taken into account when deciding on the suitability of a particular bentonite for a specific purpose.
The purpose of this document is to provide information that will enable a decision to
be made as to whether or not a particular bentonite will produce a satisfactory support
fluid, and to give guidance on the preparation, use, re-use and disposal of the bentonite
slurry, and also on methods of testing.
