Mechanical Behavior of Gypseous Soil Treated with Lime

Geotechnical and Geological Engineering, 2020
Gypseous soil is a problematic soil that is very sensitive to moisture variations and loses its strength upon saturation. Lime stabilization is traditionally used to enhance gypseous soils for civil engineering constructions. Studies on gypseous soils stabilized with lime have shown that the effectiveness of the treatment is largely dependent on the ...

Soil–Water Characteristic Curve of Gypseous Soil

Geotechnical and Geological Engineering, 2014
The soil–water characteristic curve (SWCC), also known as soil–water retention curve, is a key tool in assessing the behavior and properties of unsaturated soil. The SWCC of gypseous soil with 0, 5, 15 and 25 % gypsum content was determined, using tensiometric plate, osmotic membrane and vapour equilibrium techniques, with suction pressures ranging ...

A study on leaching of collapsible gypseous soils

International Journal of Geotechnical Engineering, 2019
A leaching study to investigate the characteristics of gypseous soil from Baher Al-Najaf in Iraq on samples taken from three sites with different gypsum contents was performed in this work.

Influence of Acetic Acid on Gypseous Soil

Materials Science Forum, 2020
Gypseous soil disturbed in many regions in the world. Existence of this soil with high gypsum content caused many damages to the buildings and structures that built on it due to dissolve and leaching of the gypsum slates by the flow of water through the soil mass. Therefore, it is necessary to study the properties of such soil.

Volume Change Behavior of Gypseous Soil

Journal of Materials in Civil Engineering, 2017
The susceptible characteristics of gypseous soil with variations in water content pose several engineering problems due to volume change behavior. A series of oedometer tests have been performed to understand the swell strains and compressibility of soil containing varying gypsum content after curing for different periods.

Deformability of gypseous soil in Iraq

2009
The main aim of this paper is to find the effect of soaking and to evaluate and document the natural and soaked deformabilities of compact Iraqi natural and soaked gypsiferous soils. In the text of this paper the two words gypseous and gypsiferous and the two words deformability and stiffness modulus are used interchangeably.

Compressibility Characteristics of Gypseous Sandy Soils

Geotechnical Testing Journal, 1994
Abstract Soils containing gypsum as a cementing agent are affected considerably when subjected to changes in water content. Seepage through sandy gypseous soil causes serious damage to foundations built on such soils. A testing program was conducted on undisturbed soil specimens with three different gypsum contents to study the ...

Treatment of collapse of gypseous soils by grouting

Proceedings of the Institution of Civil Engineers - Ground Improvement, 2013
Gypseous soil is a collapsible soil, which causes large deformations in buildings that are constructed on it. Various methods have been used to minimise this effect, such as replacing the gypseous soil or using soil stabilisation (grouting or soil improvement).

Comparison between artificial gypseous soil with free gypsum soil

2018 1st International Scientific Conference of Engineering Sciences - 3rd Scientific Conference of Engineering Science (ISCES), 2018
In this study, three samples of soils are prepared in the laboratory. The first sample is natural gypseous soil bring form Wady Sheshen region in Salahaddin governorate. The second sample Gzypsified soil prepared in laboratory as correct method and the third sample prepared by mixing of gypsum treated in a facility for building purposes with the same ...

Hydrogeological Properties of Gypseous soils in South Africa

South African Journal of Geology, 2019
Abstract Gypseous soils occur in the western arid and semi-arid regions of South Africa and Namibia. These soils exhibit a complex nature and abnormal behaviour due to their gypsum content and as such they have become more prevalent in research.
