gypsum use in cement manufacturing
How is gypsum used in building?
Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, a hardening retarder in portland cement. Varieties of gypsum known as satin spar and alabaster are used for a variety of ornamental purposes; however, their low hardness limits their durability.

How Cement is Made
There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches.

Why cement is called portland cement? When first made and used in the early 19th century in England, it was termed portland cement because its hydration product resembled a building stone from the Isle of Portland off the British coast.The first patent for portland cement was obtained in 1824 by Joseph Aspdin, an English mason.
