Collapsible soils are present in arid and semi-arid regions in an unsaturated state and are
considered to be one of the problematic soils that face engineering and geotechnical …

This paper investigates the effect of the soaking process on gypseous sand soils. The recent
research investigates the time-based soaking method on high gypsum contents (29%) of soil …

This paper presents laboratory experiments on the effect of matric suction on the
compressibility of unsaturated gypsum sand soil. The samples were obtained from Al-Najaf …

This study looks into the influence of matric suction on the volume change of gypsum sand
soil in unsaturated conditions. The specimens were collected from Al-Najaf, Iraq, and …

Gypseous soil covers approximately 30% of Iraqi lands and is widely used in geotechnical
and construction engineering as it is. The demand for residential complexes has increased …

This study examines the impact of varying soaking durations on collapse potential (CP)
within gypsum sand soil containing 29% gypsum content. It explores the enhancement of CP …

Whenever collapsible soils occur, whether by natural processes or human activities, they
pose serious engineering and geotechnical issues [1]. The effects of the rains were minimal …

This paper investigates the water volume changes in gypseous sand soils within the change
in matric suction and under different stress levels. The present research aims to examine …

This study aims to analyze the behavior of soils containing gypsum, specifically focusing on
the impact of gypsum content and different soil parameters. Several physical tests and …

Water level rise as well as inundation to gypseous soil medium can lead to a substantial loss
of volume of the soil, with or without adding load. Macromechanical behavior of gypseous …
