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.
