White Portland cement is made like ordinary Portland cement, except that its raw materials do not contain iron oxide, so you should not use clay, but in this case, the cost goes up, so use the same raw materials and give it chloride. Calcium or calcium chloride is added, which is combined with iron oxide in a cement kiln to give iron chloride, which is a gas that jumps and turns white in color.
White cement should not contain more than 0.02% by weight of iron oxide. Up to 8% by weight of calcium chloride or calcium chloride is added and then the white cement clinker is ground with gypsum to obtain white Portland cement. Also, for the preparation of colored cement, clinker grinds white cement with a maximum of 2% of mineral paints or soft stones of colored stones.
