Types Of Cement
1. Ordinary Portland Cement (OPC)
Most common type of cement.
Used for general construction work.
Comes in grades like 33, 43, and 53 (based on compressive strength in MPa at 28 days).
Example: OPC 43 grade is widely used for RCC structures.
2. Portland Pozzolana Cement (PPC)
Made by blending OPC with pozzolanic materials (fly ash, volcanic ash, etc.).
Advantages:
Low heat of hydration → good for mass concrete.
Resistant to chemical attacks.
Better long-term strength.
Ideal for dams, marine structures, and sewage works.
3. Rapid Hardening Cement
Gains strength faster than OPC.
Used when early formwork removal is required.
Suitable for roads, bridges, and urgent repair works.
4. Low Heat Cement
Generates less heat during hydration.
Used in mass concreting like dams to avoid cracking.
5. Sulphate Resistant Cement (SRC)
Resistant to sulphate attacks in soil or water.
Ideal for coastal areas, chemical plants, and sewage structures.
6. White Cement
OPC manufactured with low iron content → white color.
Mainly used for decorative purposes, flooring, and plastering.
7. Colored Cement
White cement mixed with pigments.
Used in architectural finishes, tiles, and precast decorative elements.
8. Blast Furnace Slag Cement (BFSC)
Contains ground granulated blast furnace slag.
Resistant to chemical attacks and has lower heat of hydration.
Suitable for marine structures, foundations, and pavements.
9. Oil Well Cement
Special cement for high temperature and high pressure wells.
Used in oil and gas drilling.
10. Hydrophobic Cement
Repels water → used in wet or humid conditions.
Helps in waterproof construction.
