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.","lang":"eng"}]},{"date_updated":"2023-01-17T07:45:59Z","oa":"1","date_created":"2021-05-04T08:48:48Z","author":[{"first_name":"Sebastian","id":"38243","full_name":"Pawelczyk, Sebastian","last_name":"Pawelczyk"},{"full_name":"Kniepkamp, Marieluise","last_name":"Kniepkamp","first_name":"Marieluise"},{"first_name":"Steffen","last_name":"Jesinghausen","orcid":"https://orcid.org/0000-0003-2611-5298","id":"3959","full_name":"Jesinghausen, Steffen"},{"first_name":"Hans-Joachim","full_name":"Schmid, Hans-Joachim","id":"464","last_name":"Schmid"}],"title":"Absolute Rheological Measurements of Model Suspensions: Influence and Correction of Wall Slip Prevention Measures","main_file_link":[{"url":"https://www.mdpi.com/1996-1944/13/2/467","open_access":"1"}],"doi":"10.3390/ma13020467","publication_status":"published","publication_identifier":{"issn":["1996-1944"]},"quality_controlled":"1","year":"2020","citation":{"ieee":"S.

Usually, for parallel-plate geometries, the tip-to-tip distance is used for calculation of absolute rheological values, which implies that there is no flow behind this distance. However, several studies show that this is not true. Therefore, the measuring gap needs to be corrected by adding the effective gap extension    δ    to the prescribed gap height    H    in order to obtain absolute rheological properties. In this paper, we determine the effective gap extension    δ    for different structures and fluids (Newtonian, shear thinning, and model suspensions that can be adjusted to the behavior of real fluids) and compare the corrected values to reference data. We observe that for Newtonian fluids a gap- and material-independent correction function can be derived for every measuring system, which is also applicable to suspensions, but not to shear thinning fluids. Since this relation appears to be mainly dependent on the characteristics of flow behaviour, we show that the calibration of structured measuring systems is possible with Newtonian fluids and then can be transferred to suspensions up to a certain particle content.</jats:p>"}],"status":"public"}]
