The effect of the 2/15 fluorite/gypsum ratio on the clinker was more noticeable at 1300 °C. Xray diffraction (XRD) TOP. Table 4 and Figures 4, 5, and 6 show the identification and quantification of clinker phases with and without mineralizers. In order to ensure a good fit of the calculated pattern to the observed data, we looked for a weightedprofile Rvalue (Rwp) below 10% for all samples.
The finely powdered mixture of clinker and gypsum is marketed as standard Portland cement (PC, often called ordinary Portland cement), which is then mixed with water. The mass ratio of water to cement, w/c, typically

China's CN: Cement, Lime Gypsum: Gross Profit Ratio data is updated monthly, averaging % from Dec 2006 to Oct 2015, with 83 observations. The data reached an alltime high of % in Sep 2011 and a record low of % in Aug 2015.
A metered proportion of crushed, dried limestone is fed to the finish grinding mill, along with clinker and gypsum. In almost all cases, the limestone used in PLC is the same limestone used as a raw material for cementmaking at that plant.

Supersulfated cements contain about 80% ground granulated blast furnace slag, 15% gypsum or anhydrite and a little Portland clinker or lime as an activator. They produce strength by formation of ettringite, with strength growth similar to a slow Portland cement.

The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process. Portland cement, the most widely used cement type, contains 95% cement clinker.
Portland cement Wikipedia. Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to .
carried out. The raw materials were ground together at ratio of 50 % clinker, 30 % calcined clay, 15 % limestone and 5 % gypsum. Four blends of cement were produced and used for carrying out the various tests. In addition to these four blends, a laboratory cement blend was produced using industrial grade metakaolin, MetaCem 85 and limestone A with same clinker and gypsum as the trial blends.
The Sulfoaluminate Belite clinker can be produced by burning limestone, bauxite and gypsum at around 12000C. For production of Sufoalluminate Belite cement the Lime Saturation Factor (LSF) requirement is low around, which reduces the consumption of limestone stone in manufacture.

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. Gypsum is added to control the "setting of cement".
Srikanth has given a good answer but there is a lot more to making cement than simply adding gypsum to Portland cement clinker. Pure Portland cement clinker, if ground on its own would be difficult to use in most normal construction applications because of the setting time.
Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C 1500 °C The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum.
