| 摘 要： | 本文以西北粘土为对象,对其压实行为、热传导、膨胀特性,以及吸附和渗透性能进行了初步研究,借以探讨西北粘土在高放废物处置中用作回填材料的可行性。试验表明,以西北粘土为基材,经过适当的热改性和吸附改性,在初始含水量约为9%,于70MPa 下成型,用作高放废物处置中的回填材料是可行的。

| Abstract: | A preliminary examination on the physical and chemical properties,such as compactability,thermal Conductivity,swelling capacity,adsorbability and permeability,of north-western clay werecarried out.Some additives were tested for improvingthe thermal and adsorptive properties.The clay-based material,when compacted under the pressure of 70 MPa with initial water content of 9%,wasconsidered suitable to be used as backfill material in high level radioactive waste disposal. |
