What is the purpose of adding gypsum in cement?

Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.

Abstract The constant use of natural gypsum as setting retarder in cement has led to the reduction of its high purity stock in Greece. The aim of this project was to investigate the possible displacement of natural gypsum (CaSO 4 ·2H 2 O) in cement (CEM I and CEM II types) with alternative setting retarders such as i) anhydrite, ii) phosphogypsum and iii) FGD gypsum.

Role of gypsum on microstructure and strength of soil

It has been observed that the unconfined compressive strength of soil deteriorates on the addition of gypsum for both short-term and long-term periods. The variations in strength have been attributed to changes in mineralogical and microstructural changes with the formation of new minerals such as zeolite.
