摘要：

This study deals with the rheological properties of self-consolidating concrete (SCC) incorporating various percentages of metakaolin (MK) and silica fume (SF) as a partial replacement of cement. Plastic viscosity and yield stress were evaluated at different slump flow values using a concrete viscometer. The effect of high range water reducing admixture (HRWRA) dosage and the total time for flow, the time to reach 500 mm diameter (T50), and the final diameter of the slump flow test were also investigated and studied in this research program. The results showed that the plastic viscosity and the yield stress increase with the increase of the percentage of MK. The results also demonstrated a correlation between the final slump flow diameter and the yield stress similar to that presented in the literature.
