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 …

Gypseous soil is located in dry and semi-arid areas in unsaturated conditions and this type
of soil becomes a serious issue for engineering and geotechnical when it becomes wet. the …

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 …

Gypseous soils are soils that contain sufficient quantities of gypsum that are considered
collapsible soil. The present study's objective is to predict the shear strength parameters (c …

This paper shows the different in the volumetric strains between the Oedometer tests with
different soaking durations and the unsaturated triaxial tests. The disturbed samples were …

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 …

Gypsum soils suffer from engineering problems of collapse, which occurs when an increase
in moisture causes significant soil deformation in the constructions. There is no sufficient …

Gypsum is a soluble bonding substance that is one of the soil's problematic components in
Iraq's west. This component dissolves during the wetting process. The behavior of bonded …

Accurate prediction of the soil shear strength parameters is essential in the reliable
geotechnical design of civil engineering structures. This recent paper investigates the effect …

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 …
