Description:
Portland Cement 52.5N (EN 197-1 CEM I) is a high-quality cement ideal for demanding construction projects requiring superior strength and durability. This cement grade is designed to offer a compressive strength of 52.5 MPa (minimum) after 28 days, making it perfect for high-rise buildings, roads, bridges, and industrial applications. It meets international standards and ensures excellent performance in both normal and challenging environments.
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.
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.
