Clinkerization Cement Plant Optimization
Clinkerization. The process of clinkerization signifies conversion of raw meal into clinker minerals mainly consisting of C4AF (Aluminoferite), C3A (Aluminite), C2S (Belite) and C3S (Alite) phases along with small percentage of free lime CaO, MgO, Alkalies, Sulphates etc. The conversion taking place in kiln system as raw meal is heated gradually to

The influence of P2O5 on clinker reactions ScienceDirect
1984-1-1 It has been claimed that 2.5% P20s in cement mixes is the upper limit allowed for producing satis- factory cements. This is based on Nurse's relation that for each I% P20s added to a cement mix C~S is lowered by 9.9% and C2S raised by 10.9%.

2018-9-18 Raising of C2S content renders clinker harder to grind, reduces early strength, decreases resistance to freezing and thawing at early ages and decreases heat of hydration. The hydrolysis of C2S proceeds slowly. At early ages, less than a month, C2S has little influence on strength and hardness.

2021-8-4 Clinker, when added with gypsum (to control the setting properties of cement and ensure compressive strength) and ground finely, produces cement. Clinker can be stored for long periods of time in a dry condition without degradation of quality, hence it is traded internationally and used by c ement manufacturers when raw materials are found to be scarce or unavailable.
