Recent innovations are presented herein to evaluate the rheological properties and
static segregation resistance of SCC quantitatively. Both the falling ball viscometer and the segregation probe prove to have high potential for field testing due to the simple theoretical background, the easiness of applying the measurement, the lightweight equipment, and the rapid testing procedure. The precision and reproducibility of the introduced methods need to be further investigated. These testing methods along with the multi-pair electrode conductivity method can be used as quality control methods. They help to improve the understanding of the material behavior. The results of this part of the work can be closely related to other research conducted at ACBM. For example, segregation probe test can be used to study the robustness of SCC, and the yield stress and viscosity measurements can help to understand the formwork pressure produced by SCC. It is necessary to develop a test method to evaluate the dynamic segregation of concrete.
