|Title:||Development of a Reference Material for the Calibration of Cement Paste Rheometers|
|Published:||April 22, 2013|
|Abstract:||Rheometers are usually calibrated using a standard reference oil. On the other hand the calibration of rheometer for paste or concrete cannot be calibrated using an oil as it is a Newtonian fluid, while the rheometers are designed to measure non-Newtonian materials. A granular reference material that could simulate a Bingham fluid as cement paste was developed in this study. The mixture is a mixture of corn syrup, water and fine limestone. Later sand and coarse aggregates could be added to develop a mortar or concrete reference materials. This paper illustrates the various aspects of the development and show data obtained with various geometries of rheometers.|
