Abstract
This paper presents the results of an interlaboratory study of the rheological properties of cement paste and ultrasound gel as reference substance. The goal was to quantify the comparability and reproducibility of measurements of the Bingham parameters yield stress and plastic viscosity when measured on one specific paste composition and one particular ultrasound gel in different laboratories using different rheometers and measurement geometries. The procedures for both in preparing the cement paste and carrying out the rheological measurements on cement paste and ultrasound gel were carefully defined for all of the study’s participants. Different conversion schemes for comparing the results obtained with the different measurement setups are presented here and critically discussed. The procedure proposed in this paper ensured a reasonable comparability of the results with a coefficient of variation for the yield stress of 27% and for the plastic viscosity of 24%, despite the individual measurement series’ having been performed in different labs with different rheometers and measurement geometries.

N1 - Funding information: The phenomena mentioned are only a few important aspects which cause erroneous measurements and misinterpretations in rheological experiments. An extended overview of the available techniques, their capabilities and limitations can be found in [, ]. This multitude of challenges has led to the development of a large number of different measurement setups in the following named geometries, some of which are employed in current interdisciplinary research within the Priority Programme SPP 2005 “O pus F luidum F uturum —Rheology of reactive, multiscale, multiphase construction materials”, funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG). Open Access funding provided by Projekt DEAL. The authors thank the Deutsche Forschungsgemeinschaft (DFG) for funding this research within the DFG Priority Programme 2005 “O pus F luidum F uturum ” under the grants 387096404 (HA 7917/3-1), 387118319 (LO 1393/3-1), 387092747 (SCHM 3365/1-1), 387065685 (GA 519/10-1), 411375374 (LO 751/26-1), 387066140 (KR 4948/1-1), 387095311 (ME 2938/19-1), 387152958 (ME 2938/20-1), 387153567 (ME 2938/21-1), 403524381 (SCHM 1429/16-1), 386871659 (WI 1911/25-1), 386869775 (STE 1086/18-1), 387065993 (GE 1973/28-1).
