Anhydrite usually occurs in arid places forming from the dehydration of gypsum. Please reconnect, Authors & If the screed is mixed with water in correct proportions that water is required for a chemical reaction. Abstract Gypsum is the dihydrate form of calcium sulfate. Note: Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates.In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant.One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. It is a rare mineral since much of its existing specimen alter to the much more gypsum when altered. At room temperature, insoluble anhydrite dissolves very slowly to the extent of 0.24 g per 100 g of water and does not absorb moisture from the air. Find more information on the Altmetric Attention Score and how the score is calculated. Dissolving gypsum in water or soil results in the following reaction: CaSO. 2H 2 O, is the hydrated form. Answer : The conversion of Gypsum(CaSO4. & Anhydrite is a hard crystal with a hardness rating of 3.5 and approximate density of 3.0. C. Robertson, Richard A, Robie, " and Kenneth G.
