Abstract: This paper is dealt with the fresh concrete behaviour of different kinds of concrete mixes. It is examined whether any correlation exists between workability test parametesr and rheological properties i.e. yield stress and viscosity. One objective of the study is to examine if it possible to classify a concrete mix due to today's workability tests with respect to the rheological parameters. It is shown that, although the scatter is rather high, some correlation is present between workability and rheology if only one rheology parameter is varied i e. the viscosity or the yield stress. By dividing the workability parameters into groups, a classification of a SCC can be made, utilizing simple diagrams.
