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.

how to increase C3S & reduce freelime in clinker - Page 1

2013-12-4 · re how to increase C3S & reduce freelime in clinker. Dear All. I am thinking to increase the % of Petcoke to 90% instead of 80% in the fuel mix. It will reduce the silica content by from fuel ash & will automatically result in more lime for combination & will result in more C3S & less C2S.I think it will also give reduction in free lime.

Conversion C2S to C3S - International Cement Review

First, C2S and free CaO dissolve in clinker melt. Then, calcium ions migrate toward the C2S through chemical diffusion. Finally, the C3S is formed and crystallized out of the liquid. Without a liquid phase, the diffusion of Ca ions towards C2S would be extremely slow, and that of C2S almost impossible at commercial clinkering temperatures.

However, C2S beta is the most used and expected due to its reactivity; it is the most common in cement. α shows a slower reactivity and γ does not react. C3A is also well known to have two possible polymorphs in cement like cubic or orthorhombic phases.

Cement hydration: the role of adsorption and crystal

The finely powdered mixture of clinker and gypsum is marketed as standard Portland cement (PC, often called ordinary Portland cement), which is then mixed with water. The mass ratio of water to cement, w/c, typically ranges from 0.3 to 0.5, although sufficient water to fully react with cement would require w/c to be about 0.38 or greater.
