Portland Pozzolana Cement (PPC) – Calcined Clay Based is a blended cement designed to improve durability, workability, and long-term performance while reducing clinker consumption. In this variant, calcined clay acts as the pozzolanic material instead of fly ash, making it particularly relevant in regions where fly ash availability is limited.

Calcined clay based PPC supports sustainable construction by lowering carbon emissions and enhancing resistance to chemical attack. In India, this cement is regulated by the Bureau of Indian Standards (BIS) under IS 1489 (Part 2). As per the Cement (Quality Control) Order, 2003, BIS (ISI Mark) certification is mandatory for the manufacture, sale, and import of this cement.

At Standphill India, we provide expert guidance and end-to-end support for manufacturers navigating the BIS certification process for Portland Pozzolana Cement (Calcined Clay Based), ensuring compliance with IS 1489 (Part 2).

What is IS 1489 (Part 2)?
