In East and Middle Anatolia, where several heavy industrial plants are planned to be constructed, vast areas are covered by gypsiferous layers. In this investigation, geotechnical properties of the gypsum layer, encountered at the Sivas IVth Iron and Steel Complex Site, are investigated and an attempt is made to propose solutions to some of the geotechnical problems anticipated at the site. In the research several physical, chemical and engineering properties of gypsum, the changes caused by the environmental conditions on its mechanical behaviour and crystal structure, its stress-strain-time behaviour and effect on foundation concrete are investigated and recommendations on the precautions to be taken are presented.read more

Characterization and modeling of long-term stress–strain behavior of water confined pre-saturated gypsum rock in Kurdistan Region, Iraq
TL;DR: In this article, the effects of soaking time and confined water pressure on the strength of rock due to dissolution of gypsum, rock samples with 96% of the content collected from Kurdistan Region in northern Iraq were investigated.

An experimentally verified model of the seepage progress due to dissolution of soluble particles in foundations subject to intergranular flow
C. M. Baena,M. Á. Toledo +1 more
TL;DR: In this article, a finite element method is used to calculate the solution front advance (the zone where the dissolution is taking place) of gypsum and limestone dams, with the main aim of delaying the dissolution process and avoiding damage or loss of functionality during dam lifespan.

Geomechanical Characterization of Evaporitic Rocks
TL;DR: In this article, the main physical and geomechanical properties of evaporitic rocks (evaporites) are discussed. But the authors focus on sedimentary rocks of chemical origin composed mainly of chlorides, carbonates and sulfates such as halite, gypsum and anhydrite.

Temperature effect on gypsum-bearing soil and supported (building) foundations: The case of the Central Storage Facility of Villar de Cañas, Spain
TL;DR: In this article, the authors examined the processes for the case of the Central Storage Facility for high-level radioactive waste planned in Spain, which would impose a thermal load over a long period of time due to the disposal of spent nuclear fuel.

Gypsum and anhydrite in foundations of hydraulic structures
A. N. James,A. R. R. Lupton +1 more
TL;DR: In this paper, the authors examined quantitatively and predictive methods put forward on the basis of laboratory measurements, which lead to the conclusion that gypsum tends to be less dangerous than anhydrite.
