Abstract
The invention relates to a rheometer (100) for high-viscosity materials and to a device and a method for estimating, by means of such a rheometer (100), the feeding pressure to be applied in order to overcome the feeding resistance of high-viscosity material in a pipe. The rheometer (100) has a receptacle for holding high-viscosity material in the receptacle. The receptacle is designed as a standard pipe section (102) that can be filled with high-viscosity material (300). In the rheometer (100), the standard pipe section (102) and high-viscosity material (300) filled into the standard pipe section (102) can be made to linearly move relative to each other at a first rate and at another rate differing from the first rate. A unit (146, 147, 148) for determining a rate of the relative movement of the high-viscosity material (300) and the standard pipe section (102) as well as a unit (160) for determining a pressure applied to the high-viscosity material (300) as a result of the relative movement of the high-viscosity material (300) and the standard pipe section (102) are provided as a measuring instrument.
