PPC is manufactured by inter-grinding 65% of cement clinker with 30% of fly ash and 5% of gypsum in a closed circuit ball mill with a high-efficiency separator to achieve the required fineness.
Advantages of Using PPC:
- Using PPC eliminates surface cracks due to low heat of hydration.Setting time is slightly more than OPC, which gives PPC more workable time.
- Strength development continues even after 28 days, giving ultimate higher strength to the concreate.
- Our addition of Fly Ash improves particle size distribution and gives a perfect concrete matrix.
- PPC is less porous than OPC, making it even more resistant to chemical attack.
- PPC is a more eco-friendly type of cement, with less production energy required to make each ton of cement by blending in high strength Fly Ash, a by-product from thermal power plants, which historically was disposed of through environmentally un-friendly, long-term land filling.
- The manufacturing cost of PPC is lower than of OPC.
