The rheological behavior of building material suspensions plays a central role in the processability of cement bonded building materials and thus also in the rheological behavior of their properties in hardened state.
On account of the spread application of different admixtures and materials, the empirical test methods at disposal are, up to date, inadequate in their validity for assessing the rheological properties of these materials in fresh state.
Investigations with the rotational rheometer, HAAKE RheoStress 600 however, enable a comprehensive description of the rheological behavior of these materials.
Different problems with the description of the rheological behavior of fresh building material suspensions will be explained in this article. Individual measuring methods for determining these properties, as well as the results that were won in the scope of an investigation program for the development of pumping-capable self-compacting light-weight concrete will be introduced.
