Stored Clinker on the Ground

Dear all !

I have a problem about "Mutated allotropic from b-C2S( beta - Belite) to y- C2S (gama- Belite) in low temperature ( below 100 degree celsius).

In my Plant, If Clinker is so much in Silo, we have to move over to the ground and Stored it more half year.                                                                                                                                 Phenomenon: The early strenght normally increase (1 & 3 days , but 28 days is dropped.        And I had tested LOI in its, it's similar to Clinker in silo ( <0.5 %) and not humid (<0.1%) and chemical composition is the same new Clinker (Silo), That mean it well-Stored.

I'm afraid it was Mutated allotropic from b-C2S( beta - Belite) to y- C2S (gama- Belite) in low temperature ( below 100 degree celsius).

Who can help me make this trouble.

Thanks!
