Shrinkage property of bentonite-sand mixtures as influenced by sand content and water salinity
TL;DR: In this article, changes to material properties occurring when bentonite was modified by addition of sand and exposure to different pore water salinities were considered, and the shrinkage of bentonite-sand mixtures may degrade the performance of a clay barrier constructed in waste disposal facilities.

Chemical interaction and hydraulic performance of geosynthetic clay liners isothermally hydrated from silty sand subgrade
TL;DR: In this paper, the effects of the silt aggregation, compaction density, and water content of the subgrade on the hydration of five different geosynthetic clay liner (GCL) products were reported based on a series of laboratory column experiments conducted over a six-year period.
