Collapse deformations of gypsum sands
Conclusion Gypsum silty sands with water-saturation under loading acquire collapsibility properties, whose magnitude depends on the water content, the dry density, the content of water-soluble salts, and the pressure. For sands containing highly soluble salts and gypsum, $ ε_{Sl} $ varies from 0.004 to 0.16, and for sands containing highly soluble salts amounting to 2.5–2.7%, $ ε_{Sl} $=0.002–0.10. For $ w_{0} $>0.1, gypsum silty sands are practically noncollapsible.
