Cement - Wikipedia
By far the most common type of cement is hydraulic cement, which hardens by hydration of the clinker minerals when water is added. Hydraulic cements (such as Portland cement) are made of a mixture of silicates and oxides, the four main mineral phases of the clinker, abbreviated in the cement chemist notation, being: . C 3 S: Alite (3CaO·SiO 2); C 2 S: Belite (2CaO·SiO 2);

Re: clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and . This means that c.1.55 tonnes of raw mix are required and c.0.55 tonnes of CO2 are lost due to calcination of the CaCO3 in the raw material. The clinker factor is therefore 0.65 x the amount of raw mix.
