White Portland cement is used to manufacture white concrete for prestigious construction projects and decorative work in conjunction with white aggregates. White concrete typically takes the form of prefabricated cladding panels, because using white cement for structural purposes is not economical.
White Portland cement is also used to manufacture brightly colored concretes and mortars in combination with inorganic pigments. When used with pigments, ordinary cement creates colors that may be appealing but somewhat slow. Bright reds, yellows, and greens can be easily created with white cement. It may also be possible to make blue concrete at some cost.
The cement mixer will add the pigments. Instead, many suppliers sell ready-mixed painted cement to ensure repeatable quality, utilizing white cement as a basis. WOPC’s whiteness is calculated as the powdered content with a reflection cost of more than 85%.
Monocouche renders are a strong achievement in the use of WOPC and additional pigments. In some nations, an off-white clinker is developed at a price just a little above standard gray clinker, which provides a reflectance quality over 70 when the floor. If combined with field blast furnace slag up to 60 percent depending on use and early strength it is possible to produce a cement with a representation of more than 80. Mixed cement may cost less than General Purpose Portland cement (gray) manufacturing but usually generates a premium as it is priced to contend with white Portland cement.
Other main features of White Portland Cement are given below:
- The color of cement in white cement is a particularly important problem. Nevertheless, the accuracy of light and sound are the main concerns.
- The appearance of white cement is determined by the nature of the raw materials and the production process.
- This concrete is constructed of very limited iron oxide and manganese oxide raw materials. Such oxides have an effect on white Portland cement whiteness and undertone.
- China clay is commonly used for white concrete combined with chalk and calcareous.
- The oil used as gas for the kiln in white cement to prevent contact of coal ash.
- Different measures must be added to the white cement manufacturing process.
Uses of White Cement
- It finds its use in architectural design, interior and exterior decorations, walls, ornamental concrete items such as idols because of its whiteness, while grey cement is mainly used for construction purposes.
- Used inroads due to the high reflectivity property to add visibility to median highways.
- White cement is also used for the manufacture of precast members in large quantities. The white Portland cement makes use of beautiful precast parts.
- They ‘re also commonly used to make cast stones look attractive.
- White cement is a comparatively costly form of cement and is therefore only used selectively.
- Used for colored concrete to create brightly colored concretes and mortars use inorganic pigments.
