This blog explains BIS certification requirements for Fly Ash Based Portland Pozzolana Cement as per IS 1489 (Part 1), covering composition, applications, mandatory ISI mark, certification process, cost, penalties, and benefits.

Portland Pozzolana Cement (PPC) – Fly Ash Based is one of the most widely used blended cements in India due to its improved durability, environmental sustainability, and long-term performance. PPC is manufactured by inter-grinding or blending Ordinary Portland Cement clinker with fly ash, a pozzolanic material obtained from thermal power plants.

The use of fly ash not only enhances the engineering properties of cement but also supports sustainable construction by utilizing industrial by-products. In India, Fly Ash Based Portland Pozzolana Cement is regulated by the Bureau of Indian Standards (BIS) under IS 1489 (Part 1). As per the Cement (Quality Control) Order, 2003, BIS (ISI Mark) certification is mandatory for the manufacture, sale, and import of PPC.

At Standphill India, we provide expert guidance and end-to-end support for manufacturers navigating the BIS certification process for Portland Pozzolana Cement, ensuring compliance with IS 1489 (Part 1).
