Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) 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 behind only water as the planet's mostconsumed resource.

Cement milling is an essential process in the manufacturing of cement. There are several types of cement mills that are used in the milling process, including ball mills, vertical roller mills, roller presses, and horizontal ring roller mills. Each type of cement mill has its unique characteristics that make it suitable for a particular purpose.

Fortunately, the b structure is easily stabilized by the other oxide components of the clinker and thus the g form is never present in portland cement. The crystal structure of bC 2 S is irregular, but considerably less so than that of C 3 S, and this accounts for the lower reactivity of C 2 S.

Materials ground Portland clinker is the main constituent of most cements. In Portland cement, a little calcium sulfate (typically 310%) is added in order to retard the hydration of tricalcium aluminate. The calcium sulfate may consist of natural gypsum, anhydrite, or synthetic wastes such as fluegas desulfurization gypsum.
