Kalsiumsulateilla

Kalsiumsulateilla, also known as calcium sulfate hemihydrate, is a chemical compound with the formula CaSO4·0.5H2O. It is a white, crystalline powder that is commonly used in various industrial and construction applications. The compound is formed when calcium sulfate dihydrate loses half of its water of crystallization.

In the construction industry, kalsiumsulateilla is primarily used as a retarder in cement and concrete mixtures. It slows down the setting and hardening process, allowing for better workability and longer mixing times. This property makes it valuable in large-scale construction projects where precise timing is crucial.

Additionally, kalsiumsulateilla is used in the production of plaster and gypsum board. It is also employed in the manufacturing of certain types of paper and as a desiccant in various industrial processes.

The compound is relatively non-toxic and has low environmental impact, making it a preferred choice in many applications. However, like any chemical, it should be handled with care to avoid inhalation or skin contact.
