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.

Thixotropy and dilatancy

open access: yesClay Minerals, 1966
AbstractThe matric potential of water in gels of five-sixths neutralized aluminium montmorillonite (bentonite) and aluminium kaolinite changes during periods of shear and periods of rest. Shear increases the potential of water in bentonite gels, and in kaolinite gels containing little water, but decreases the potential in kaolinite gels containing more

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.

Assessment of proprioceptive decline in chronic ankle instability: a comparative evaluation of sub-modalities

open access: yesFrontiers in Sports and Active Living
PurposeRecurrent ankle sprains in chronic ankle instability (CAI) individuals are strongly linked to impaired proprioception, but the specific mechanisms underlying these impairments remain incompletely understood.
