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 concrete is

Measuring Rheological Properties of Cement Pastes: Most common Techniques, Procedures and Challenges
Publikováno v:
RILEM Technical Letters, Vol 2, Pp 129-135 (2017)
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 description of flow

The article at hand builds on previously published work (Secrieru et al., 2017) [1] by providing a detailed discussion on the formation of a lubricating layer (LL) and the flow type during pumping of cement-based materials. It is demonstrated that kn

This study quantifies the changes in the rheological properties of fresh concrete while focusing on lubricating layer (LL) formation during pumping. Full-scale pumping experiments were carried out on ready-mix concrete accompanied by the state-of-the

For the first time, a first-order physical correlation between pumping parameters (pressure and flow rate), granular skeleton properties (particle diameter and packing properties) and LL properties (thickness and viscosity) is proposed. This correlat
