ABSTRACT:
Device and methods for rotationally mixing and rheological testing of sample liquids, such as cement particle suspensions, employ mixing blades and shear-resistant members having substantially noncoincident orbital paths. Rheology is assessed by measuring the resistance of the liquid to rotation of the device. Both rheological and calorimetric testing can be performed during mixing, which ensures uniformity of rheology and hence the accuracy of results.
