The cement is the most demanding and essential raw material used in various production and construction activities. The cement industry has witnessed a steady growth in the market as different range of products using cement are manufactured. It is a binder, a raw material substance that serves as an adhesive to other materials. Cement mixed with water and fine aggregate produces mortar, sand and gravel to create concrete. It is the most-consumed resource and is widely available in the market. * Portland Cement is the most common type of cement used for concrete, and stucco. Types Of Cement We offer include: Ordinary Portland Cement Portland Pozzalana Cement White Cement Portland.
Origin :- Vietnam . Turkey
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.
