Role of Gypsum in Cement and its Effects
In the intricate process of manufacturing cement, gypsum enters the stage after the formation of clinkers. These clinkers, having undergone cooling, are combined with a small quantity of gypsum before heading to the final grinding phase. For ordinary Portland cement, the gypsum content hovers between 3 to 4%, while quick-setting cement may …

Resistance to Grinding and Cement Paste Performance of
Gypsum (C 0 G 100) is the softest material among the studied; however, it has a sharp feed PSD and low size, which can increase the resistance to grinding. This is seen by gypsum's initial fineness (n = 1.42), which has a narrower PSD than limestone (n = 0.70). The uniformities of the materials were very similar after being ground by the ball ...

Clinker Grinding Techniques in Cement Manufacturing
Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.

Cement Grinding
OPC is produced by the inter-grinding and blending of 95% clinker with 5% gypsum to a fineness of 280 m 2 /kg. PPC is produced by the inter-grinding and blending of 65% clinker with 30% fly ash and 5% gypsum to a fineness of 320 m 2 /kg. Fineness is a controlled parameter for cement to ensure better hydration and strength development.

2 Gypsum dehydration during cement production
The proportions of gypsum, hemihydrate and anhydrite are individually optimized for each type of cement [7]. The dehydration of gypsum to hemihydrate normally takes place during the grinding process in the cement mill. Depending on the mill temperature, the gypsum becomes partially or completely dehydrated to hemihydrate or anhydrite respectively.
