文摘

Volumetric shrinkage behavior of four Indian bentonites was established using various laboratory techniques. The limitations of the studied VSC techniques were evaluated using VSC models and by establishing Sr based SWCC data. The VSC techniques suffered from several limitations in accurately establishing the SWCCs for engineering applications. The present study recommended using clod technique with modifications for establishing Sr based SWCCs.
