Identifying Viscosity of Cement Paste from Mini-Slump-Flow Test

For high-performance concretes, including self-consolidating concretes, to be successful, rheological property quality control is proving to be critical. No tests that are widely accepted for quick and accurate determination of these properties exist, however. Qualitative workability is current assessed through the slump-flow test. However, using a rheological description for a more complete view of workability can be provided through yield stress, viscosity, and other fundamental parameters. The correlations between yield stress and the final spread of the slump-flow tests, as well as between cement paste and mini-slump-flow tests, have been shown through previous studies. Demonstrating a relationship between time to final spread and cement paste viscosity is the intention of this study. Paving the way to an ultimate relationship for concrete can be assisted by this information, even though the study examines cement paste. Adequate quality control measures will be able to be provided for today's high-performance concrete by the slump-flow test with this relationship.
