Study of the microstructure of a collapsible soil flooded with NaCl saline

Abstract

Collapsible soils are unsaturated soils which may undergo inter-granular rearrangement with abrupt and significant volume reduction after wetting. The large settlement resulting from the soil collapse pushed for deep studies of these types of soils. The experimental study consists to illustrate the influence of the salt concentration, compaction energy and moisture content on the change of microstructural characteristics of the reconstituted soil and reduction of the collapse potential.
