Cement Kilns: Clinker Minerals

Alite is the main mineral (>50%) in most modern clinker, and is the characteristic mineral of Portland cement. Alite only becomes stable above 1250°C, and cant form unless the burning temperature gets above that at some stage.

Clinker (cement) - Wikipedia

In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Portland cement clinker - Understanding Cement

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Cement - Wikipedia

Conversely, hydraulic cement hardens by hydration of the clinker minerals when water is added. Hydraulic cements (such as Portland cement) are made of a mixture of silicates and oxides, the four main mineral phases of the clinker, abbreviated in the cement chemist notation, being: C 3 S: Alite (3CaO·SiO 2); C 2 S: Belite (2CaO·SiO 2);

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

3.6 - Mineral and Oxide Composition of Portland …

3.6 Mineral and oxide composition of portland cement. When considering the composition of a portland cement, the most important factors are the relative amounts of each of the cement minerals, the amount of calcium sulfate, and the total amount of alkalis (Na and K).

Cement Kilns: Clinker

Clinker minerals react with water to produce the hydrates that are responsible for cement’s setting and strength-giving properties. Reaction with water occurs only at the surface of the clinker particle, and so only proceeds rapidly if the clinker is finely ground to produce a large reaction surface.

Clinker, during construction of buildings throughout the ages, cement was always preferred as one of the important building materials. It combines with different components such as cement, sand and water, then becomes a mortar, and when used in the structure, it dries after a certain period of time to provide the desired hard floor.

Portland Cement Clinker - an overview | …

Portland Cement Clinker. Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO2 and 2CaO.SiO2), the remainder consisting of aluminium and iron containing clinker phases and other compounds.

Cement mill - Wikipedia

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
