The analysis of published data and our experimental results showed that the existing estimates of gypsum solubility in water (Cm↑) at 25°C range from 0.0147 to 0.0182 M. Such a scatter (more than 20%) is the result of a combined influence of experimental conditions and ability of gypsum to form supersaturated solutions. This influence appears most noticeable during gypsum dissolution in a dispersed state. Under such conditions, equilibrium is determined with a precision of no better than ±4.5… 
The Kinetics of Gypso Anhydrites Dissolution in Water: Experimental Studies
Experiments on the kinetics of gypso anhydrites dissolution in water (25°С, 0.1 MPa) resulted in the development of a model of the process in the form of balance equations of dissolution kinetics for
Experimental Study on Early Age Characteristics of Lime-GGBS-Treated Gypseous Clays under Wet–Dry Cycles
Gypseous soils are capable of presenting ground construction challenges to civil and geotechnical engineers due to their unpredictable deformation characteristics. These undesirable responses are
Short- and Long-Term Effects of Lime and Gypsum Applications on Acid Soils in a Water-Limited Environment: 3. Soil Solution Chemistry
Aluminum (Al) toxicity imposes a significant limitation to crop production in South Western Australia. This paper examines the impact of surface-applied lime and gypsum on soil solution chemistry in
Short- and Long-Term Effects of Lime and Gypsum Applications on Acid Soils in a Water-Limited Environment: 1. Grain Yield Response and Nutrient Concentration
Surface (0–10 cm) and subsoil (soil layers below 10 cm) acidity and resulting aluminum (Al) toxicity reduce crop grain yields. In South Western Australia (SWA), these constraints affect 14.2 million
