Study on the enhancement of thixotropic properties of steel slag-based digital concrete by metakaolin

open access: yesCase Studies in Construction Materials
To improve the utilization rate of waste steel slag, metakaolin was preferably selected as a thixotropic enhancer to prepare a high-thixotropic steel slag-based digital concrete slurry applicable to the digital concrete process.

Unusual Time Dependent Rheological Behavior of a Concentrated Suspension

open access: yesApplied Rheology, 2017
The time dependent rheological behavior of a concentrated CaCO3 particle suspension is studied. The particles are suspended in a mixture of three industrial products: two resins, composed of styrene monomer, a styrene-butadiene-styrene block copolymer ...

Spatial-Temporal Phenomena in the Flows of Multi-Component

open access: yesApplied Rheology, 2015
Measuring the rheological properties of multi-component (and multi-phase) systems meets with many special problems which are absent in flows of homogeneous materials. Such complex fluids have inherent structure and all the peculiarities of their behavior

Anti-thixotropic dynamics in attractive colloidal dispersions: a shear restructuring driven by elastic stresses [PDF]

open access: yesarXiv
Due to rich rheological properties, dispersions of attractive colloidal particles are ubiquitous in industries. Specifically, upon experiencing a sudden reduction in shear rate, these dispersions may exhibit transient behaviors such as thixotropy-where viscosity increases over time-and anti-thixotropy, characterized by an initial viscosity decrease ...

Physical Aging and Thixotropy in Sludge Rheology

open access: yesApplied Rheology, 2008
Sewage sludge presents a dual rheological behaviour with an abrupt change between the two regimes. Using a new technique of reconstruction of the velocity profile, the behaviour can be modelled by a unique equation including liquid and solid components ...

Self-compacting concrete with reduced formwork pressures

open access: yesActa Polytechnica CTU Proceedings
Self-compacting concrete (SCC) is normally characterized with high pressures exerted on the formwork during casting. The pressures can easily exceed bearing capacity of a regular formwork when casting a high structural member in one step.
