Standard Test Method for Measuring Rheological Properties of Cementitious Materials Using Coaxial Rotational Rheometer

Importancia y uso:

5.1 Rheological properties provide information about the workability of cementitious paste or mortar. This test method may be used to measure flowability of a cement paste or the influence of a specific material or combination of materials on flowability.

5.2 As rheological properties are sensitive to sample heterogeneities, special care is needed using this procedure so that sedimentation, particle migration away from the spindle or slippage at the surface of the spindle and container, is avoided.
