Standard Practice for High-Shear Mixing of Hydraulic Cement Pastes

Importancia y uso:

5.1 This practice is useful in laboratory research on rheology of hydraulic cement systems as it has been shown to provide a paste with rheological properties similar to those obtained in a concrete from which the aggregate had been removed.6 Mixing of paste using C305 is not satisfactory as the paste is not thoroughly mixed, due to the absence of sand. In this practice the shear imparted to the cement paste is significantly higher than in C305 and therefore it is known as high-shear mixing.
