PORTLAND CEMENT 32.5 - 42.5 N/R - 52.5 - CRS PACKING : BULK - 25/50 Kg - Big Bag / Pallet CERTIFICATIONS : ISO 14001-2015 AFAC AFNOR INTERNATIONAL AND CE ORIGIN : ALGERIA
Our Cement is a fine powder, obtained from the calcination at 1,450 C of a mix of limestone, clay, and iron ore. The product of the calcination process is clinker the main ingredient of cement that is finely ground with gypsum and other chemical additives to produce cement. We offers an array of blended cements which have a lower CO2 footprint resulting from their lower clinker content due to the addition of supplementary cementitious materials. The use of blended cements reinforces our strong dedication to sustainable practices and furthers our objective of offering an increasing range of more sustainable products.
42.5 Portland Grey Cement
We offer white cement and is available in 25 kg bag or jumbo bags.
PORTLAND CEMENT TYPE I/II Low Alkali ASTM C150 Mill sheet will be provided upon request. 52.5 and 42.5 Monthly capacity: 52.5 - 150000.0 MTs 42.5 - 500000.0 MTs
We manufacture this type of cement with limestone, low iron content kaolin clay, and gypsum. Customers use our White Portland Cement in architectural works requiring great brightness and artistic finishes, to create mosaics and artificial granite, and for sculptural casts and other applications where white prevails.
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.
We offer high quality white cement (52.5) for 50 kg bag or as per customer requirement. Our materials are good for construction projects and decorative works.
Microsilica (silica fume) is a by-product from silicon metal or ferrosilicon industries, is an amorphous silicon dioxide SiO2. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete. White Cement advantages: Sustainability: Solar Reflectance Index (SRI): Floors finished with white or pastel color concrete will have a much higher SRI than floors with gray concrete, therefore they will reflect light better, and generate energy savings for the lifetime of the floors. Reduction of Heat Island effect: By constructing buildings with white concrete roofs or light-colored roof tiles, the Heat Island Effect is reduced from surfaces generating less heat and improved reflectivity. Architectural Concrete: White Portland Cement is ideal for decorative concrete and Architectural Concrete applications, Masonry and Cementitious Building Products. A key advantage of using white cement for these applications is that it provides a base color that can be tinted to custom colors to meet any color spectrum demand.
