This page is a short introduction. The Understanding Cement book/ebook contains a more detailed description of the hydration process and the hydration products. Clinker is anhydrous (without water) having come from a hot kiln. Cement powder is also anhydrous if we ignore the small amount of water in any gypsum added at the clinker grinding stage.

Cement Clinker is an intermediate product used in manufacture of Portland and Blended Cements in Cement. Portland cement clinker is ground (usually with the addition of a little gypsum, that is, calcium sulfate dehydrate) to a fine powder and used as the binder in many cement products. As a whole it is a good project for entrepreneurs to invest.

The range of clinker composition may be fairly wide if the amount of liquid phase increases slowlyC~s). A clinker with about 25% liquid phase from a raw-mix is generally considered an ideal raw-mix for kiln lining, fuel saving, rapid C3S formation through the dissolution of CIS and CaO, and economical clinker grinding.
