Use of Bentonite Slurry in Pile Foundation Cast in-situ

Aug 29, 2018· Bentonite is the name used for a range of clays that can swell and gel when mixed with water. Bentonite is naturally found in form of sodium montmorillonite which exhibits thixotropic properties i.e. when bentonite is mixed with water it form a gel under static conditions but when disturbed or when distressed it regains its fluidity.. During piling operation i.e. auger boring, the slurry is ...
