Title: Determination of Rheology of Self-Consolidating Concrete Using the 4C-Rheometer and How to Make Use of the Results
Abstract: Abstract One of the major obstacles to a more wide spread use of self-consolidating concrete is to obtain further understanding of the importance of rheology on the final concrete quality. Existing test methods does not support the concept of two independent rheological properties in a very comprehensive manner. For this purpose, the so-called 4C-RheometerDanish Technological Institute, Taastrup, Denmark. has been developed in Denmark, combining the traditional slump flow test with digital video analysis to obtain the slump flow versus time curve from which the yield stress and plastic viscosity are determined. Based on numerous on-site tests in Denmark performed with the 4C-Rheometer, ranges of preferred rheological parameters have been identified for different types of castings. This paper presents the concept of testing and the correlation of obtained rheological parameters to the BML viscometer and discusses the selection of rheological properties for some typical horizontal and vertical castings.
