| Description | Bentonite is a clayey rock, which is planed to be used as an engineer barrier at building a deep storage of nuclear waste. The bentonite sample from the deposit Rokle and two reacting media, both natural and synthetical waters, were used for the experimental study of the mineral stability in aqueous environment at temperature of 95 C. From experimental data, changes of chemical composition of the system were quantified. Based on the program Geochemists Workbench, the model of bentonite-water interaction was derived. Major changes in the composition of water takes place during the first three months and the composition of water has very little effect on stability and properties of bentonite. |
