This paper describes the development of a rheometer for Self-Compacting Concrete (SCC) that is installed in a concrete mixer and provides results of the rheological properties immediately at the end of the mixing process.
The intention was to find a way, to evaluate the flowability and the rheological properties of SCC automatically, directly after the mixing process has finished. At the end of the mixing process the rheometer immerses in the concrete and starts the measurement. At this time a correction of the mixture is still possible, before it is filled into the truck. In a first step, a laboratory rheometer was built and the measurement procedure was developed. In a second step the laboratory rheometer was installed in a 75 l concrete mixer and data were collected and evaluated. Test results of different mix designs showed to be very accurate.
