Discussion on Determination of Yield of Bentonite

Yield is an important parameter of bentonite.The determination of this parameter is quite complex and time consuming. Lack of known properties of clay samples and difference in laboratory operator's skills play an important role in the success of the determination. Repeatability of determining the yield of bentonite is poor, and different persons measuring the yield of the same bentonite sample may give different results. It has been found that these problems can be mitigated or even eliminated using Excel's trend line fitting function. Validation of experiment data proves that clay suspension formulated with bentonite determined by the "trend line fitting" function has Fann35 readings closely agree with theoretical values, indicating that this method of yield determination is accurate and efficient.
