| Abstract: | Systematic studies including mineral composition and structure,physico- chemical properties and thermal properties have been conducted on Gaomiaozi bentonite,Xinghe County,Inner Mongolia Autonomous Region.The compac- tion characteristics of bentonite and the influence of additive to bentonite have been discussed.The analysis of mineral composition and structure show that the bentonite ores are dominated by montmorillonite.Preliminary studies of the characteristics of ores indicated that Na-type bentonite from the deposit has good absorption,excellent swelling and high cation exchangeability.The com- pressibility of bentonite will be improved by adding the additives such as quartz sand.The studies indicated that the characteristics of Gaomiaozi bentonite can satisfy the requirement of buffer/backfilling materials for HLW repository and the ores can be selected as the preferential candidate to provide buffer/backfill- ing materials for HLW repository in China. |
