Influence of shear stress applied during flow stoppage and rest period on the mechanical properties of thixotropic suspensions [PDF]

, 2008
We study the solid mechanical properties of several thixotropic suspensions as a function of the shear stress history applied during their flow stoppage and their aging in their solid state.

Effect of Bentonite Admixture Content on Effective Porosity and Hydraulic Conductivity of Clay-based Barrier Backfill Materials

Medžiagotyra, 2023
Clay-based barrier wall has been diffusely employed as vertical barriers. Nevertheless, there were few project practices of these walls in China. And few research have been performed to study the impact on the permeability of the addition of domestic ...

Antibacterial Activity of Cetyltrimethylammonium Bromide Modified Silver-Bentonite

MATEC Web of Conferences, 2016
Organo-Ag-bentonite was prepared by the attachment of cationic surfactant cetyltrimethylammonium bromide on silver(A)g-exchanged bentonite. The prepared samples were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy

CHARACTERIZATION OF MODIFIED BENTONITE USING ALUMINUM POLYCATION

Indonesian Journal of Chemistry, 2010
The modification of bentonite by pillarization using aluminum polycation type Keggin [Al13O4(OH)24(H2O)12]7+ has been carried out, by exchange of cation from interlayer with aluminum polycation.

Factors affecting metal mobilisation during oxidation of sulphidic, sandy wetland substrates [PDF]

, 2010
Most metals accumulate as sulphides under anoxic conditions in wetland substrates, reducing their bioavailability due to the solubility of metal sulphides. However, upon oxidation of these sulphides when the substrate is occasionally oxidised, metals can
