摘要
密实砂-膨润土混合物作为高放废料地质处置的缓冲材料,人们越来越关心它的性质。通过大量的试验,研究了密实砂-膨润土的膨胀特性,阐明了其膨胀过程和方式,得出了一些有意义的结论。
As buffer materials for repositories of high-level nuclear waste, compacted sand-bentonite mixtures are becoming more attract- ing. Based on a number of swelling tests, the swelling process fo compacted sand-bentonite mixtures are explained, and some useful con- clusions are presented.
