The constituents needed to produce Ordinary Portland Cement (OPC), the most used type of cement, are clinker and gypsum. The OPC contained approximately 9397% of the share of clinker (Feiz et al., 2015). During the grinding process, a small amount of the gypsum is added to the mix to control the hydration rate of the cement setting process.

Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.
