Summary

The near-field acoustic sensor detects the density and the viscosity of liquids, and the emergence of elastic properties of evolving media. During the processing of cement, strong variations of the rheological properties are involved in the paste. Because of these strong variations (from viscous fluid to solid), different devices must be used to characterize the processing. The near-field acoustic sensor both follows the alterations of the viscous paste and the emergence of the rigidity of the cement.
