Raw Material Preparation

Preparation of cement raw materials Alite approximately Ca 3 SiO 5 provides almost all the early strength strength up to seven days of curing of cement and a moderate amount of late gt 7 days strength Belite approximately Ca 2 SiO 4 provides very little early strength and a large amount of late strengthSo it can be seen that these small compositional changes have a large effect...
