9 Types of Portland Cement and their Applications
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 complex and expensive to manufacture.
