Our plant at Nimbahera (Rajasthan) is amongst the most modern cement plants in the country, and it was set up in technical collaboration with ThyssenKrupp and Pfeiffer ltd., world leaders in cement technology.
Currently, we have three products. Portland Pozzolana Cement (PPC). Ordinary Portland Cement (OPC). Wonder Cement Xtreme. Although each of these products has a different purpose, at their core, they are all consistent when it comes to quality.
This quality is a result of our relentless pursuit of perfection and the tech-focused innovation we are deploying across departments.

Special cement introduction
Special cements are cements that serve some specific function such as altering the setting or hardening behavior of a concrete, producing different colors for architectural effects, imparting superior workability, imparting water retention and plasticity to mortars, resisting the penetration of water in walls or containment vessels or simply reducing the cost of the cementing agent. This article gives descriptions of the basic characteristics of certain special cements and their applications.
Those described include: calcium sulfoaluminate cements, calcium aluminate cements with special setting and hardening properties, cements with special colors (white Portland and buff-colored).
Calcium Sulfoaluminate cement is special cement because of its high-speed bonding, rapid strength development, and a shrinkage reduction. We also called them as CSA Cement in short. Oreworld CSA cements are classified by two types: one is CSA cement and the other is CSA binder which does not add anhydrite but CSA pure clinker powder.
The CSA cements have three grades classified by the strength in three days; CSA42.5, CSA52.5 and CSA 62.5.
Regarding the CSA binder, there are three grades, too. They are CSA binder 52.5, CSA binder 62.5 and CSA binder 72.5. The CSA binder is pure CSA clinker powders that without adding anhydrite. Most of the traders or plants who have their own plants and can mixing the anhydrite like the CSA binder best because it can save production and transportation cost.
The CSA binders can be produced to different types of dry-mix mortars based on CSA cements. For example, self-leveling mortar, concrete repair mortar, tile adhesives, no-shrinkage mortar and etc.
Special cement Characteristics
• Appearance: light grey powder
• Early-high strength
• Rapid setting: initial setting time can reach 12~20 minutes
• Tiny expansion and low shrinkage
• Low degree of shrinkage
• Low alkali: PH value is about 11 and lower than Portland cement.
• No rust to steel
• Freeze-thaw resistance
• Impermeability
• Resistance to sulfate attack
• Low carbon footprint
Special cement Application
• Concretes repair (for example bridges, airport runaways and parking apron, etc.)
• Technical Rapid-Setting Mortars (for example restoration and repairs, etc.)
• Self-Leveling Floor Screeds
• Sprayed Concretes and Shotcretes
• Mining Products, for example: mining roof support materials.
• Plasters & Mortars (i.e. Joints, Sulfate Resistance, No-Shrinkage, etc.)
• Special adhesives, tile adhesives
• Concrete Precast Products
• Glass fiber reinforced concrete (G.R.C.) less
Special cements are cements that serve some specific function such as concretes repair, Self-Leveling, Rapid-Setting Mortars. We provide CSA cement, csa binder, Calcium Aluminate Cement, High Alumina Cement, White Portland Cement and other special cement.

Description of high alumina cement
High Alumina Cement (HAC, sometimes known as calcium aluminate cement (CAC) or aluminous cement) is composed of calcium aluminates, unlike Portland cement which is composed of calcium silicates. It is manufactured from limestone or chalk and bauxite.
Application of High alumina cement
There are two distinct ways to use calcium aluminates: as high-performance binders and as mineral reagents in a variety of industries. High alumina cement concrete and high alumina refractory are two important products.
As binders, high alumina cement is used in concretes and mortars for specialized applications for their properties of resistance to corrosion, abrasion and heat combined with rapid hardening and the ease of controlling grading variations. High alumina cement concrete is a good example for this use.
High Alumina cement is also used in combination with other fine components. Hydraulic binders with new properties are then obtained. In this way, aluminates act as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix.
As reagents, high alumina cement is found in non-hydraulic systems. This is the case in metallurgical treatments (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature melting properties and for trapping molten metal impurities.
High alumina cement package
by 50kgs bag. Store in shady, cool and dry place. Avoid stamp and mix with other substance. less
High Alumina Cement (HAC, known as calcium aluminate cement (CAC) or aluminous cement) is mineral of amorphous calcium aluminate (non-crystalline calcium aluminate). Oreworld Trade is a professional high alumina cement suppliers.
