Rheology of high performance shotcrete

Denis Beaupré
The main goal of this study was to develop high performance shotcrete and to provide a fundamental understanding of the shooting process. For this, a laboratory concrete pump, to pump and/or shoot a number of shotcrete mixes, and a rheometer, to measure the rheological properties on the fresh shotcrete, were designed and constructed. A model based on rheological behavior was finally developed to predict pumpability and shootability. The values of both flow resistance and torque...
