Aug 06, 2013· re CEMENT MILL PERFORMANCE WITH CLINKER QUALITY VARIATION. Hello Dharmesh, I agree with 123red. The number, distribution and size of belite (C2S) clusters have a significant effect on clinker grindability. This is because C2S is the least brittle clinker mineral and therefore the most diffiicult to grind.

Since calcium silicates (C3S and C2S) - are the main cement compounds (occupies about 75% of cement weight) - they are responsible for the final strength of the hardened cement paste. With time: -The rate of hydration decreases continuously. -The size of unhydrated cement particles decrease.
The tri- and di-calcium silicates (C3S and C2S, respectively) comprise over 80% by weight of most cement. It is known that C3S is the most important phase in cement for strength development during the first month, while C2S reacts much more slowly, and contributes to the long-term strength of the cement.
