Special Cements

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).

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.)
