Rheological and texture analysis methods for quantifying yield value and level of thixotropy [PDF]

open access: yes, 2017
This study compares different methods for the assessment of yield stress and level of thixotropy in semisolid emulsions, using three instruments: an air-bearing controlled-stress rheometer, a T-bar viscometer and a texture analyser. The following methods

Multiscale Modeling of Thixotropy in Soft Clays

open access: yes, 2019
Thixotropy is a material property that describes how a substance can 'soften' upon continues deformation and heal back to the 'thicker' state over time when left to rest.

Analytical modelling of thixotropy contribution during T/C fatigue tests of asphalt concrete with the VENoL model

open access: yes, 2021
The classical modelling of fatigue tests carried out in the laboratory on asphalt concrete consists in predicting the decrease in the overall complex stiffness modulus.

Thixotropic evaluation of bentonitic clay dispersions modified with nonionic surfactants for organic drilling fluids

open access: yesCerâmica
The use of nonionic surfactants to modify the surface of bentonite is still quite restricted, although many advantages of that method can be found in the literature, like superior stability and low toxicity.

The influence of calcium nitrate on the plasticizing effect of cement paste

open access: yesJournal of Civil Engineering and Management, 2016
The rheological properties of the cement pastes have been determined using a rotational viscometer under a special testing routine by increasing and retaining a steady rotation speed of the viscometer cylinder up to certain values and for a certain time.

Investigation on the Flow and Thixotropic Properties of Alkali-Activated Concrete

open access: yesBuildings
Alkali-activated materials (AAMs) offer an eco-friendly alternative to traditional Portland cement, yet their rheological properties, particularly in concrete mixtures, remain largely underexplored.

Muscle Thixotropy: More than Just Cross-Bridges? Response to Comment by Campbell and Lakie [PDF]

open access: yes, 2007
Although Campbell and Lakie in a Comment to the Editor in this issue of Biophysical Journal suggested that exclusive cross-bridge action is behind muscle thixotropy, recent findings and our preliminary observations suggest that additional mechanisms ...
