[ Modeling of cement clinker chemistry and engineering of cement manufacturing process : State of the art ] ... During clinker formation in the rotary kiln, reactions such as decarbonation of CaCO 3 and MgCO 3, clinkerization reactions and formation of a liquid phase take place in the kiln. These reactions may be endothermic or exothermic. The combustion of fossil fuel and/or alternative fuels ...

Clinker — Wikipédia

Le clinker est un constituant du ciment, qui résulte de la cuisson d'un mélange composé d'environ 80 % de calcaire (qui apporte le calcium) et de 20 % d'aluminosilicates (notamment des argiles qui apportent le silicium, l'aluminium et le fer). La « farine » ou le « cru » est formée du mélange de poudre de calcaire et d'argile. Cette cuisson, la clinkérisation, se fait à une ...

Alite formation Alite forms by the transition of some of the belite to alite and also directly from free lime and silica to alite. This occurs rapidly once the clinker temperature is above about 1400 °C.

Cement - WikipediaTraduire cette page

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is only behind water as ...

Belite - WikipediaTraduire cette page

Relatively high belite reactivity is desirable in Portland cement manufacture, and the formation of the unreactive γ-form must be rigorously avoided. This is achieved by rapid cooling, forming crystals that are small, distorted and highly defective. Defects provide sites for initial water attack. Failure to cool the clinker rapidly leads to inversion of belite to the γ-form. The γ-form has ...

Parametric Studies of Cement Production ProcessesTraduire cette page

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

It has been found that a change in granulometry of raw meal has a significant impact on the formation rate of the clinker phases. Subsequently, the grindability of the clinker and the strength of the cement are influenced, especially in the short-term hydration.
