White Portland Cement

ASTM C-150 Type 1
Type 1 Portland Cement is a general purpose cement suitable for all uses where the special properties of other cements are not required. White Portland cement is made of selected raw materials containing negligible amounts of iron and magnesium oxides - the substances that give gray cement its color. White Portland cement is used primarily for architectural purposes such as decorative concrete, terrazzo, stucco, grout, masonry mortar, cast stone and swimming pool plaster.
