2.Silica SiO 2 Silica or silicon dioxide is the second largest quantity of cement ingredients which is about 17 to 25. Silica can be obtained from sand argillaceous rock etc. Sufficient quantity of silica helps for the formation of di-calcium and tri-calcium silicates which imparts strength to the cement.

Ferrite is a fluxing agent. It reduces the melting temperature of the raw materials in the kiln from 3000 F to 2600 F. Though it hydrates rapidly it does not contribute much to the strength of the cement. Magnesia MgO The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants.
