Sodium activation and mechanism of the performance difference of two montmorillonite samples

QIU Jun1,ZHANG Yan-gui2,LU Xian-jun1(1.College of Chemical and Environmental Engineering,Shandong University of Science and Technology,Qingdao Shandong 266510,China;2.Laiwu Institute of Supervision and Inspection on Product Quality,Laiwu Shandong 271100,China)  
Na-bentonite has better properties than Ca-bentonite.Therefore,sodium activation of Ca-bentonite is an effective ways of improving properties and applying values of Ca-bentonite.In this paper,the two key parameters,sodium carbonate dosage and slurry concentration,were studied,and the structure and the properties of Na-montmorillonite were tested at the same time.The mechanism of the difference of the performance of the two montmorillonite were also analyzed.
