IS 1489 (Part 1)
Portland Pozzolana Cement-Part1 Fly-ash based
Summary
Portland Pozzolana Cement (Fly Ash Based) is a blended cement made by inter-grinding Portland cement clinker with fly ash. It offers improved durability, better workability, lower heat of hydration, and enhanced resistance to chemical attack, making it suitable for mass concrete and long-lasting construction.
Why BIS Certificate is Mandatory for PORTLAND POZZOLANA CEMENT – FLY ASH BASED ?
BIS certification is mandatory for Portland Pozzolana Cement to ensure compliance with Indian Standards for strength, durability, and safety. Cement is a critical construction material, and BIS certification prevents substandard products, ensures structural safety, protects consumers, and maintains uniform quality in construction projects across India.
