The hydration of cement is an exothermic process. This means that a considerable amount of heat is evolved in this chemical reaction, which is termed as the heat of hydration. This heat surges the temperature of the paste. The instant water is added, the temperature suddenly hikes up due to the aluminates reacting with water (initial reaction).
Reactions which take place as the feed passes through the kiln are reviewed below. They can be considered under three broad headings: Decomposition of raw materials - temperatures up to about 1300 °C. Alite formation and other reactions at 1300 C-1450 °C in the burning zone. Cooling of the clinker.
Hydration. Introduction. Portland cement is a hydraulic cement, hence it derives its strength from chemical reactions between the cement and water. The process is known as hydration. Cement consists of the following major compounds (see composition of cement ): Tricalcium silicate, C 3 S. Dicalcium silicate, C 2 S. Tricalcium aluminate, C 3 A.
ball cement reactions; The Cement Manufacturing Process - Advancing Mining.

This reaction takes time, because the partial pressure of carbon dioxide in the air is low. The carbonation reaction requires that the dry cement be exposed to air, so the slaked lime is a non-hydraulic cement and cannot be used under water. This process is called the lime cycle. Conversely, hydraulic cement hardens by hydration when water is ...
