Study of Nano-Additives Influence on Physical Properties of Bentonitic Clay
The interaction between bentonitic clays and exchangeable cations Na+, К+, Ca++, and Mg++ is studied theoretically. It is stated that the insertion of exchangeable cations into the interlaminar space leads to reducing of the interlayer distance as compared with that calculated for the undoped clay. At that, the clay particles having Mg++ on their surface demonstrate more stable structure upon the increase of moistening. The calculation results for Mg++ compare well with the experiment performed.
