polymorphs in cement like cubic or orthorhombic phases. Moreover, more to the polymorph coexistence, some trace phases are present (lime, portlandite, periclase.) and some additives are added in cement to improve final properties. Gypsum is one of them and will control the milling dehydration process; this phase is often accompanied

Manufacturing cement is highly energyintensive. First, energy is used in the form of fuel to fire the rotary kilns to produce the cement clinker. Second, electrical energy is used to operate various units – in particular raw material and cement grinding systems. Today, electrical energy consumption in cement works makes up over 10 per cent ...

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction. The ideal temperature to further avoid moisture attraction ...

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime, for example, results in undesirable effects such as ...
