The effects of shearing on the rheological behaviour of thixotropic bentonite muds
Abstract The bentonite muds, widely used in civil engineering and in the oil industry, have a Binghamian and thixotropic behaviour that impedes their flow. It has been shown that vibrations, whatever may be their characteristics, are ineffective for improving this flow. Techniques aimed at applying large and slow shearing actions are no better: the thixotropy reduces considerably the size of the flow zone in the vicinity of the shearing surface, even with low concentrations of mud. It is now obvious that if one wishes to cause a large zone of bentonite mud to flow, it is necessary to reduce the thixotropy with the help of appropriate additives.
