Excess alumina weakens the cement. Magnesia: Magnesium Oxide. Chemical formula is MgO. Magnesia should not be present more than 2% in cement. Excess magnesia will reduce the strength of the cement. Iron oxide: Chemical formula is Fe 2 O 3. Iron .

Manufacture of Portland cement

and are, therefore, called hydraulic cement. The name "Portland cement" given originally due to the resemblance of the color and quality of the hardened cement to Portland stone Portland – island in England.

9 Types of Portland Cement and their Applications

The smaller watercement ratio also increases the workability of the cement. White Portland Cement It is similar to Type I Portland cement, except that it is white in color. This is achieved by reducing the percentage of iron (C 4 AF) and magnesium oxide, which impart a gray color to ordinary Portland cement. Since it requires additional care in the choice of ingredients, and to produce white color, this type is .
