Portland pozzolana cement — IS 1489 (Part 1) (2015) Testing

The applicable BIS standard is IS 1489 (Part 1):2015 – Portland Pozzolana Cement – Specification: Part 1 Fly Ash Based. BIS currently lists this standard on its official website, while its product manual provides guidance for certification and conformity assessment.

Testing helps manufacturers verify that PPC meets the specified chemical and physical performance requirements. It supports quality control, BIS conformity and reliable product acceptance by customers and construction projects. Certko can support testing requirements for IS 1489 (Part 1):2015 through appropriate laboratory testing services.

The BIS product manual identifies Ordinary Portland Cement conforming to IS 269, Portland cement clinker conforming to IS 16353 and fly ash conforming to IS 3812 (Part 1) as relevant raw materials for fly-ash-based PPC.

Yes. Portland Pozzolana Cement covered under IS 1489 (Part 1):2015 is subject to mandatory BIS certification. Manufacturers must demonstrate conformity with the applicable requirements before using the BIS Standard Mark under the relevant certification scheme.

Testing includes chemical parameters such as insoluble residue, magnesia, sulphur content, loss on ignition, chloride and alkali content. Physical testing includes fineness, soundness, setting time, compressive strength and drying shrinkage, with test methods referenced to relevant IS 4031 and IS 4032 parts.

As specified in IS 1489 (Part 1):2015, the fly ash constituent in Portland Pozzolana Cement shall be 15% to 35% by mass of the cement. The fly ash used should conform to the applicable requirements of IS 3812 (Part 1).

Testing helps manufacturers confirm that fly-ash-based PPC meets specified chemical and physical requirements before supply or certification. It supports quality control, regulatory conformity and reliable cement performance. Certko can assist businesses in arranging relevant IS 1489 (Part 1):2015 testing through suitable testing laboratories.

Commonly listed tests include fineness, Le Chatelier and autoclave expansion, initial and final setting time, compressive strength at specified ages, drying shrinkage and chemical parameters such as chloride, sulphate, magnesia and alkali content.
