Abstract
SCC can encompass a wide range of concrete rheology. Previous research has shown the importance of specific rheological characteristics for application requirements such as reduced formwork pressure, increased static and dynamic segregation resistance, and increased pumpability. The required rheological characteristics for different applications are discussed in terms of yield stress, plastic viscosity, and thixotropy. Micromortar rheology measurements were conducted with four different high-range water reducers (HRWR) and two different water/cement ratios to demonstrate potential differences in rheology due to HRWR selection. The results indicated that HRWR selection can significantly impact micromortar rheology.
