Abstract
The paper presents scientific basis of development of nanobentonite and the results of investigations using progressive research methods as well. The researches were carried out on bentonite upgrading obtained from Alpout field of Gazakh region and its properties studied. It has been defined that the mass content of bentonite may be increased from 70 up to 97 % via content cleaning from foreign substances, while the size of bentonite particles comprise 85-130 nm, and after upgrading 8-10 nm. Moreover, if the size of montmorillonite and bentonite crystalls in the initial sample were 13.3-19.5 nm, after upgrading process they were within 8.3-10.0 nm. The process of bentonite swelling has been studied. It was specified that the swelling of both raw and upgraded bentonite takes place in two stages. More intensive swelling of upgraded bentonite was observed in both stages. It was justified that the relations occurred via metal ions (cations) in interlayer distance with oxygen atoms contained in montmorillonite molecule are broken down due to the hydration process.
