Cement Manufacturing Process - YouTube

The water causes the hardening of concrete through a process called hydration. Hydration is a chemical reaction in which the major compounds in cement form chemical bonds with water molecules and become hydrates or hydration products. Details of the hydration process are explored in the next section.

Portland cement clinker thermochemistry. A wide range of temperature values are found in the literature. Despite the importance of the reaction, the state of knowledge is still poor, perhaps because it is difficult to determine equilibria in a reaction that is not smoothly reversible, and also because of the extraordinary difficulty in getting calcite samples of adequate purity.

HYDRATION OF CEMENT It is the reaction (s eries of chemical reactions) of cement with water to form the binding material. In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass -the hydrated cement paste.

Manufacture of Portland cement

Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions
