OPC vs PPC Cement For Civil Engineering Student
🔹 OPC (Ordinary Portland Cement)
Gains strength quickly.
Ideal for RCC works, beams, columns, and slabs.
Higher heat of hydration.
Faster setting and construction progress.
🔹 PPC (Portland Pozzolana Cement)
Gains strength more slowly but improves over time.
Better durability and crack resistance.
Lower heat of hydration.
Suitable for masonry, plastering, dams, and mass concrete works.
Key Difference:
OPC is preferred when early strength is needed, while PPC is preferred for durability and long-term performance
