Effect of Additives on the Performance of the Fire-Clay Refractory Bricks

Eurasian Chemico-Technological Journal, 2010
This work studied the effect of additive materials – ceramic powder, bentonite, and clay-on the performance of fire-clay refractory bricks. The results showed that as the percentage of ceramic powder, clay, or bentonite increased up to 1.5%, shrinkage of

Settling of bentonite in gelatine solutions [PDF]

, 2011
New Zealand has a sizeable meat by-products processing industry, associated with significant aqueous effluent called stickwater. Stickwater has a biological oxygen demand of 50-150 g O₂/l and has to be treated prior to disposal.

Enhanced Rheological and Filtration Performance of Drilling Fluids Using Fe3O4/Saponin/Cu(II) Nanocomposites: Synthesis, Characterization, and Application

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Drilling fluids used in high‐performance well operations often struggle to maintain rheological stability, colloidal dispersion, and filtration control under harsh downhole conditions. This study engineered a multifunctional Fe3O4@Saponin/Cu(II) nanocomposite to address these challenges.

Molecular Insights Into the Water Freezing on Kaolinite Surfaces: The Key Role of Surface Properties

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Unfrozen water content is a key factor governing the physical properties of frozen soils, and variations in mineral surface properties play a critical role in determining this content. However, the fundamental physical mechanisms of how different mineral surfaces affect soil water freezing remain poorly understood.

Modelling the thermo-mechanical volume change behaviour of compacted expansive clays [PDF]

, 2009
Compacted expansive clays are often considered as a possible buffer material in high-level deep radioactive waste disposals. After the installation of waste canisters, the engineered clay barriers are subjected to thermo-hydro-mechanical actions in the ...

Impact of Al3+ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior

ChemistryOpen, EarlyView.
The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...
