  • Cement Kilns: Clinker Thermochemistry

    The clinker manufacturing process requires a large input of energy. Part of this is due to heat losses from a process that is less than 100% efficient, but even in an efficient process, the chemical reactions involve an input of energy - an endothermic enthalpy change that can be derived from thermochemical first principles. The chemical reactions in a kiln system occur in stages as the ...

  • 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. For more information see the following pages ...

  • Clinker quality depends on raw material …

    Because consistent clinker quality is so critically important in making high-performance concrete to avoid devastating building failures, cement manufacturers are investing in new technology to improve the process. A recent article in Cement International (verlagbt.de) described how a cement company sought to stabilize the quality of their raw meal to regulate clinker quality.

    Clinker quality requires a mass ratio (CaO)/(SiO 2) which is less than 2, a C 3 S contents are above 50% and a lime saturation factor is between 90 and 98% [2]. Determining the content of free lime is especially important to judge doneness and clinker quality [3-5]. The free lime limit isn't the same for all cements; it depends on several factors, especially the temperature reached during ...

  • Cement Kilns: Special Clinkers

    A typical good-quality sulfate resisting clinker might contain 76% alite, 5% belite, 2% tricalcium aluminate, 16 % tetracalcium aluminoferrite, and 1% free calcium oxide. Because it usually has a high ferrite content, it is dark in colour. Because alkali-bearing clay is displaced from the mix by sand and iron oxide, such clinkers usually have reduced alkali contents. Alkali contents are ...
