Effects of Xanthan Gum Biopolymers on Gypseous Soils Characteristics
Tikrit Journal of Engineering Sciences, 2020 Gypseous soils are problematic soils that cause large deformations in the constructions that are built on it. Therefore, many binders have been used to reduce this impact.

TREATMENT OF COLLAPSIBILITY OF GYPSEOUS SOIL
Journal of Engineering, 2008 A series of double odometer tests are conducted to study the compressibility and collapse ofgypseous soil taken from west of Baghdad governorate. The gypsum content of the soil used isnearly 25%. Four different types of additives are selected to reduce the collapse strain of this soil.These additives are cement, bentonite, calicium chloride and ...

Geotechnical Behaviour of Gypseous Soil Treated by Geopolymer Additives
Diyala Journal of Engineering Sciences, 2023 Gypseous soil is well-known for its numerous engineering problems. When this soil is exposed to water, the gypsum in the soil dissolves, causing the buildings built on it to collapse; so, treating gypseous soil is important for improving its engineering

Stability Behavior of Lime Stabilized Gypseous Soil [PDF]
Engineering and Technology Journal, 2013 In arid and semi-arid zones, gypsum (CaSO4.2H2O) is one of the soluble of the common minerals that found in soils. In Iraq, gypseous soils is a worldwide stability problem that causes extensive damage upon wetting, and occur in certain areas characterized by variation of climatic conditions.
