Measuring and modeling the shrinkage characteristics of plastic clays

Clayey soils are generally used as liner material in landfill to prevent ground water pollution. The swelling and shrinkage soils are affected the change in the water content. Significant shrinkage caused by loss of pore water in clays may cause enormous damage to liner systems. This study presents...
