Since ancient times, people have used hydrated lime to build houses and high buildings. Today, the massive architectural works and high-rise buildings are constructed more and more. Why appear firm architectural construction? That is cement â??important hydraulic binder in building process, helping to link projects together, forming a solid mass. With modern advanced machines and science, abundant human resources. Portland cement is the most common type of cement in general use around the world, used as a basic ingredient of concrete, mortar, stucco, and most non-specialty grout. It is a fine powder produced by heating materials in a kiln to form what is called clinker, grinding the clinker, and adding small amounts of other materials. Several types of Portland cement are available with the most common being called ordinary Portland cement (OPC) which is grey in color, but a white Portland cement is also available.
Cement is a crucial building material used in construction to bind other materials together. It is a powder made from a mixture of materials, such as limestone, clay, shells, silica, and iron ore There are several types of cement, each with its own specific properties and uses. The most common types include like portland 32.5/42.5/52.5
It is a crucial ingredient if you want to achieve pure white concrete or mortar. Without its integration, standard portland cement alone will produce concrete and mortar that is grey adding titanium dioxide pigments can lighten the colour, but no concrete can be truly white without the addition of white cement mix. In this guide, we ll explore the uses and benefits of white cement, alongside other dyeing options for cement mixes.

white Portland Cement, named White Cement, is hydraulic binding materials adding gypsum and grinding into fine particles. Pure whiteness keep lightness. It's used widely in various construction and decoration ie. Painting, sculpting, flooring, terrazzo products, and also white and colored concrete components.

White cement is a hydraulic binder produced for decorative purposes by grinding white clinker, which is obtained from a mixture of special-quality clay (pyrophyllite, kaolinite) and limestone, with gypsum. It is a type of cement used in binding of elements such as tiles, ceramics in luxurious architectural structures. It is one of the products with the highest strength and whiteness in the market. This product is for buildings that require high strength, for general use and structures with aesthetic purposes. Its basic distinctive properties are high strength gain, aesthetic and decorative features, smooth surface and elegant appearance. It has a minimum whiteness rate of 85%. It has a stable shade in addition to its high level of whiteness, which provides a great advantage in the production of building elements. It can be used in colored concrete and mortar. Thanks to its high level of whiteness and fine structure, it is used in the production of building chemicals.
