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.

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.

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
