TL;DR: In this article, the results of an interlaboratory study of the rheological properties of cement paste and ultrasound gel as reference substance were presented, and different conversion schemes for comparing the results obtained with the different measurement setups are presented.
Journal ArticleDOI
Effect of Different Shear Rates on Particle Microstructure of Cementitious Materials in a Wide Gap Vane-in-cup Rheometer.
TL;DR: Investigations were carried out on the effect of shear history (shear rate variation over time) on the cement paste agglomeration state and the rheological properties of cement paste were evaluated with the Reiner–Riwlin approach to enable a model-based description.
Book ChapterDOI
Numerical Simulation of the Flow Behavior of Newtonian Fluids in a Wide Gap Rheometer by CFD
TL;DR: In this article, wide gap coaxial rheometers with vane-in-cup systems are used to determine rheological properties of cement paste, mortar and concrete, but they exhibit serious oversimplification, e.g., torque contributions of other parts than the vertical cylinder equivalent surface or neglecting of stress peaks.
Book ChapterDOI

TL;DR: In this article, a new model system of spray-dried particles was developed for the characterization of cementitious materials by Colloidal Probe Atomic Force Microscopy (CP-AFM).
