Abstract Experiments were conducted to investigate how specimen preparation (crushing and sieving) affects the swell index (SI) of bentonite-polymer (B–P) composites and the relationship between SI and hydraulic conductivity of B–P GCLs. Seven B–P and one Na–B GCLs were used in this study. Tests were conducted using DI water and synthetic municipal solid waste incineration ash leachates. Specimens were prepared using the ASTM D5890 and two alternative methods prior to SI testing. For both Na–B and B–P composites,

试样制备对膨润土-聚合物 GCL 溶胀指数的影响

摘要 通过实验研究了试样制备（破碎和筛分）如何影响膨润土-聚合物 (B-P) 复合材料的膨胀指数 (SI) 以及膨胀指数与 B-P GCL 的水力传导率之间的关系。本研究中使用了七个 B-P 和一个 Na-B GCL。使用去离子水和合成城市固体垃圾焚烧灰浸出液进行了测试。在 SI 测试之前，使用 ASTM D5890 和两种替代方法制备样品。对于 Na-B 和 B-P 复合材料，
