When it comes to choosing the right cement for house construction, both Ordinary Portland Cement (OPC) and fly ash-based cement have their merits. Let’s explore their characteristics:

  1. OPC (Ordinary Portland Cement):

  2. Fly Ash-Based Cement (PPC):

    • Composition: PPC (Portland Pozzolana Cement) contains 75-77% cement clinker, 20% fly ash, and 3-5% gypsum.
    • Advantages:
      • Heat of Hydration: PPC has a slower rate of heat of hydration, which reduces the risk of cracks and shrinkage.
      • Workability: It offers better workability and finishing due to the spherical shape and fine size of fly ash particles.
      • Durability: Fly ash refines the concrete pores, making it less porous and more durable.
    • Recommended Use:

Remember that both OPC and PPC can be substitutes for each other, but quality control and best construction practices are essential. Choose the cement type based on your specific project requirements and budget considerations! 🏠🔍
