| Type of Cement | Composition | Setting Time | Strength | Applications | Special Features |
|---|
| Ordinary Portland Cement (OPC) | Clinker + Gypsum | Initial: 30 min Final: 10 hrs | High compressive strength | General construction, concrete, plastering, and masonry work | Available in grades: 33, 43, 53, suitable for fast construction. |
| Portland Pozzolana Cement (PPC) | OPC Clinker + Gypsum + Pozzolanic materials (Fly ash, volcanic ash) | Initial: 30 min Final: 10 hrs | Moderate strength | Dams, marine structures, mass concreting, and long-term projects | High durability, low heat of hydration, eco-friendly. |
| Rapid Hardening Cement | Clinker with increased C3S content | Initial: 30 min Final: 10 hrs | High early strength | Road repairs, precast concrete elements, urgent construction | Gains strength faster than OPC. |
| Sulphate-Resistant Cement | Reduced C3A content | Similar to OPC | Moderate strength | Marine works, sewage treatment plants, foundations in sulphate-rich soils | Resists sulphate attacks effectively. |
| Low Heat Cement | Reduced C3S and C3A, increased C2S | Slower than OPC | Moderate strength | Dams, large concrete structures, and mass concreting | Minimizes heat of hydration to prevent cracks. |
| White Cement | High purity limestone with minimal iron and magnesium | Similar to OPC | Similar to OPC | Decorative purposes, tiles, and architectural designs | High whiteness, aesthetic finish. |
| Coloured Cement | White cement + Pigments | Similar to OPC | Similar to OPC | Floors, walls, and decorative applications | Available in different colors. |
| Hydrophobic Cement | OPC + Waterproofing additives (e.g., stearic acid) | Similar to OPC | Similar to OPC | Cold weather construction, water tanks, and underground structures | Resists water during storage. |
| Expansive Cement | OPC + Sulphoaluminate clinker | Similar to OPC | Moderate strength | Repairs, grouting, and shrinkage-compensated structures | Prevents shrinkage cracks. |
| High Alumina Cement (HAC) | Limestone + Bauxite | Initial: 3-4 hrs Final: 5 hrs | High strength | Chemical plants, refractory concrete, and high-temperature-resistant structures | Resists heat and chemical attacks. |
| Blast Furnace Slag Cement (BFSC) | OPC Clinker + Gypsum + Granulated Blast Furnace Slag | Initial: 60 min Final: 10 hrs | Moderate strength | Marine structures, bridges, foundations, and mass concreting | High durability, eco-friendly, resists alkali-silica reaction. |
| Quick Setting Cement | OPC with reduced gypsum content | Initial: 5 min Final: 30 min | Moderate strength | Underwater construction, tunneling, and grouting | Sets faster than OPC. |
| Masonry Cement | OPC Clinker + Limestone + Plasticizers | Similar to OPC | Low strength | Masonry, plastering, and finishing works | High workability, smooth finish. |
| Air-Entraining Cement | OPC + Air-entraining agents (e.g., resins, fatty acids) | Similar to OPC | Moderate strength | Frost-resistant concrete for cold climates | Improves freeze-thaw resistance. |
| Oil Well Cement | OPC with retarders for high-temperature and high-pressure conditions | Slower than OPC | Moderate strength | Oil well casing, high-pressure pipelines | Resists high pressure and temperature. |
| Geo-Polymer Cement | Industrial by-products (e.g., fly ash, GGBS) activated by alkaline solutions | Initial: 90 min Final: 24 hrs | High strength | Eco-friendly construction, green buildings | Very low carbon footprint, eco-friendly. |
