PLATE WATER ABSORPTION METHOD FOR BENTONITE

2016-11-11  Plate Water Absorption is a relatively good quality index for bentonite performance in iron pelletizing. However, Plate Water Absorption, measured by the conventional method, is not sufficient as it largely depends on pelletizing conditions. Due to the large complexity of interfering factors, plate values should be evaluated

Sorption Water by Modified Bentonite - ScienceDirect

2015-1-1  Natural bentonite modified with a subsequently addition of 5, 10 and 15% of Calcium and the purified bentonite (BQ, BQp BQ 5, BQ 10 and BQ 15) achieved a maximum absorption of humidity of 0.27, 0.44, 0.46 , 0.71 and 1.01 g water/g sample, respectively. Desiccants mixtures were obtained by simple mechanical mixing.

Properties Bentonite

Sodium bentonite, with sodium cation prevalence (Na+) allows water to penetrate through the platelets, forcing them apart, thus leading to swelling. Conversely, calcium bentonite, with calcium cation prevalence (Ca2+), while getting hydrated in much the same way, due to its strong positive charge, has lower absorption properties, not permitting ...

ISO - ISO 10769:2011 - Clay geosynthetic barriers ...

ISO 10769:2011 specifies a method for determining the water absorption of bentonite. The bentonite component is a part of clay geosynthetic barriers (GBR-C). Water absorption depends on the specific surface of the fine particles and the surface activity of the bentonite. The test provides an index value for production control testing of GBR-C.
