White Cement is a hydraulic binder produced by grinding Portland-Cement clinker with a controlled amount of calcium sulfate and usually with some magnesium oxide. It is used in situations where the presence of colored impurities would be undesirable or where the higher cost of white cement is offset by aesthetic or technical considerations.
The whiteness can be evaluated in terms of pigmentation, brightness and contrast, which in turn determine the whiteness index (WI) and the yellowness index (YI). White Cement differs from grey cement in its chemical composition, which requires special care during clinkerization. The clinker includes less iron and manganese oxides than those required for grey cement. In addition, raw materials are carefully selected to minimize the amount of chromium and vanadium oxides present as contaminants in the raw mix.
It is important to note that while white cement is manufactured to meet certain specifications based on physical properties, it should not be confused with paint. White cement used alone or with aggregates does not produce bright white concrete.
White Cement produces clean, bright colors, especially for light pastels. Concrete masonry units made with white portland cement create clean, sharp lines for architectural design effects such as scored surfaces. Performance characteristics
I am sure you want to know what is the white cement price 1kg. This is like any other type of cement available in the market and the prices are similar to that of ordinary gray Portland cement.
White cement is used for aesthetic purposes, use in decoration and for prestressed concrete. White cement or white ordinary Portland cement (WOPC) is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness.
Obtaining this color requires substantial modification to the method of manufacture, and because of this, it is somewhat more expensive than the gray product. It still looks like ordinary Portland cement once it hardens. The color of that hardened concrete is dependent on the choice made by the purchaser regarding color of the fine aggregate, whether natural sand or crushed stone.
White cement has essentially the same properties as gray cement, except for color. It is readily available throughout North America. The color of white cement is determined by its raw materials and the manufacturing process. Metal oxides, primarily iron and manganese, influence the whiteness and undertone of the material.
White Cement
White cement is the main raw material for making white concrete and mortar. It can also be made into colored cement by adding pigments. White cement is known for its whiteness and high strength, and it can be used in various industries such as building materials, ceramics, etc.
The Manufacturing Process of White Cement
Cement production process: The cement production process includes three steps: raw material preparation, clinker burning and cement grinding. Among them, the preparation of raw materials accounts for about 35%, the clinker burning accounts for 50% ~ 60%, and the grinding accounts for 10% ~ 15%. The new dry process is adopted in the production. Most of the raw materials are crushed by a crusher (fine crusher), then conveyed to a vertical roller mill for grinding, mixed with a certain amount of gypsum to form a powder ground material called mixed material, collected from the fine powder collector, and then sent to rotary kiln clinker burning . After cooling in the clinker cooler, and added with appropriate amount of gypsum, fly ash or slag powder, it is finally ground into cement in a cement mill.
Raw material preparation
The raw materials used in white cement manufacturing are limestone, sil
White cement is a type of special cement, belongs to decoration cement.In general, Portland cement is greyish-green, as the name suggested, white cement is white. In the cement manufacturing process, in order to get white color, we should add vitamin C or process white cement clinker with light calcium carbonate.
Nowadays, more and more people start to pay attention to the appearance of buildings and indoor decoration. White cement is more shiny than general Portland cement. Therefore, it’s the best choice for building exterior wall, faceplate, etc.
White cement price will be higher than grey Portland cement price because of its lower consumption. And it’s also hard to produce white cement because raw material for making white cement are few in the nature. The most common method is adding some pigment when making grey Portland cement and mixing them evenly. It can not only save energy but also reduce manufacturing cost and make full use of resources at the same time.

White cement is a value-added product that can be used instead of grey cement for its heat-reflecting properties and superior aesthetic appearance. White cement is made using the same process and materials as grey clinker, the only difference being the fuel used for firing. In white cement manufacture, natural gas is preferred because of its clean burning characteristics. Fuel oil or coal may also be used.
White cement differs from grey cement in terms of raw materials, manufacturing process, physical properties and end-use applications. The following are the key differences between white and grey cement:
Raw Materials
Raw materials used to produce white clinker contain less iron oxide and manganese oxide than those used to produce grey clinker. Low levels of these oxides are necessary to avoid colouration of the finished cement. Iron oxide and manganese oxide are removed by adding pure iron ore or manganese ore during grinding, or by blending imported high grade clinker with domestic clinker. In addition, small amounts of other minerals (e.g., titanium dioxide) may be added as an additional whitening agent.
