A byproduct from the FGD process, gypsum will exit the system as a slurry and enter the dewatering phase. Gypsum can be mechanically dewatered a number of different ways including the use of vacuum filters or centrifuges. Dewatering can result in a gypsum cake product which could have moisture levels as low as 5%.

On the other hand, gypsum is moderately water-soluble, and anhydrite, its associated anhydrous mineral, changes volume and swells when exposed to water (Yılmaz, 2001).Strength loss due to dissolution along with swelling due to wetting should be considered in the strength limit and service limit designs of soils treated with gypsum/anhydrite as well as …
Abstract: Agriculture has failed to be sustainable several times in the history of the world because of soil failure (Rush, 1987). Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soils and over a wide pH range including sodicity. Waste-product gypsum is available in a large ...
