Transparent model concrete with tunable rheology for investigating flow and particle-migration during transport in pipes Open
The article describes the adaption and properties of a model concrete for detailed flow studies. To adapt the yield stress and plastic viscosity of the model concrete to the corresponding rheological properties of real concrete, the model …

Experimental Insights into Concrete Flow-Regimes Subject to Shear-Induced Particle Migration (SIPM) during Pumping Open
In this paper, the authors have focused on shear-induced particle migration (SIPM), its effect on concrete flow patterns, and lubricating layer formation during pumping. For this purpose, various volume-fractions ϕ of aggregates were selec…

Measuring Rheological Properties of Cement Pastes: Most common Techniques, Procedures and Challenges Open
The science of rheology is increasingly used to describe the properties of fresh cement paste. Compared to standard workability tests, rheological properties allow for more fundamental investigation, more precise phenomenological descripti…

Rheological characterisation and prediction of pumpability of strain-hardening cement-based-composites (SHCC) with and without addition of superabsorbent polymers (SAP) at various temperatures Open
The paper at hand presents the results of an investigation into the rheological behaviour of strain-hardening cement-based composites (SHCC) with and without the addition of fresh superabsorbent polymers. The effect of temperature variatio…
