Cement Clinker - an overview ScienceDirect Topics

CEM I is ground cement clinker with a proportion of a gypsum and anhydrite mix or an alternative sulfate source (the amount limited by the SO 3 content of the cement) and is allowed to contain up to 5% of a Minor Additional Constituent (MAC). A MAC is defined in EN 197 as, ‘Specially selected, inorganic natural mineral materials, inorganic mineral materials derived from the clinker process or constituents as

Clinkerization - Cement Plant Optimization

Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.

What are Cement Clinkers? (with pictures) - wiseGEEK

2021-2-1  Cement clinkers are made from bauxite. The most commonly used cement in the world is Portland cement, which is formed at high temperatures that chemically combine the ingredients into new components, including calcium silicates and calcium aluminates. When the cement clinkers are ground with approximately 5% gypsum, they form Portland cement.
