Premium Portland Cement Clinker / Type II and I For Cement Production And Construction Color: Grey Lead time (days) 30 To be negotiated Application: Office Building Design Style: Contemporary Type: Cement Clinker Hardening Feature: Rapid Hardening HCSA BINDER is a hydraulic binder based on calcium sulphoaluminate, rather than calcium aluminates which are the basis of CALCIUM ALUMINATE CEMENT or calcium silicates which are the basis of PORTLAND CEMENT. The difference gives HCSA BINDER properties particularly suited to formulators of products such as self-leveling or self-smoothing compounds, rapid hardening screeds, tile adhesives, non-shrink grouts, rapid setting and special mortars.

Cement Clinker

Description: Our Cement Clinker (EN 197-1 CEM 1 52.5 N) is engineered for high-performance cement production, adhering to international standards. This clinker is characterized by its optimized chemical and mineral composition, ensuring superior strength, workability, and durability in cement formulations. It is ideal for producing Ordinary Portland Cement with high early strength, making it suitable for demanding construction projects. Chemical Composition: Silicon Dioxide (SiOâ??): 21.02% Aluminum Oxide (Alâ??Oâ??): 6.11% Ferric Oxide (Feâ??Oâ??): 3.89% Calcium Oxide (CaO): 65.78% Magnesium Oxide (MgO): 0.99% Sulfur Trioxide (SOâ??): 0.80% Chloride (Cl): 0.048% (Max

Natural Gypsum: Gypsum (CaSO4.2H2O) is a naturally occurring mineral mined from deposits formed by ancient sea beds as a raw material, white when pure, but commonly grey, yellow, red or brown, owing to impurities. The anhydrous form (CaSO4), anhydrite, is common. We are enlisted amongst the topmost INatural Gypsum Importers and Exporters from India. Applications: Gypsum has many industrial applications in its raw or Calcined forms, especially in the building and construction industries. Uses of Raw Gypsum are principally as: - a retarder for Portland cement - a fertilizer or soil conditioner - mineral filler - oxidizing agent in glass manufacture or other industrial applications. Most gypsum is calcined and used in the manufacturing of plaster products. Wallboard and plaster requires gypsum contents greater than 85%, although producers prefer a minimum of 94–95% along with whiteness in color. The major consumers of the Gypsum at present are Cement Industry. By weight about 4% to 6% Gypsum in crushed condition is utilized in Portland Cement Manufacture after mixing with cement/clinker. Gypsum acts as a retarder and controls the setting time of cement. Imported Gypsum from Iran: Natural Gypsum is one of the most superior qualities and consistent material available for Import and Export. Natural Gypsum has adequate whiteness, high purity as well as it is low in cost which makes it absolutely feasible for white cements as well as Plaster Of Paris manufacturing and for the Cement Industry all together. One more important quality that distinguishes Natural Gypsum from others is its hardness which is less as compared to other sources and allows different industries to easily grind the same for processing into final product which in turn results in to reduced power consumption for manufacturing industries.
