Portland - Pozzolana cement — IS 1489: Part 2 (2015) Testing

Portland Pozzolana Cement (PPC) under IS 1489 (Part 2):2015 is cement manufactured using calcined clay as the pozzolanic material. BIS specifies that the total pozzolana constituent should be between 10% and 25% by mass.

Chemical testing includes parameters such as insoluble residue, magnesia, total sulphur expressed as SO₃, loss on ignition, chloride content and alkali content. These tests help verify whether the cement meets the chemical requirements specified by the standard.

Physical testing covers fineness, soundness, initial and final setting time, compressive strength at specified ages and drying shrinkage. BIS laboratory listings identify these tests for evaluation of PPC under IS 1489 (Part 2):2015.

The standard permits calcined clay pozzolana conforming to IS 1344. A combination of calcined clay pozzolana and fly ash conforming to IS 3812 (Part 1) may also be used with the other specified cementitious materials.

BIS provides a dedicated product manual for Portland Pozzolana Cement – Calcined Clay Based under IS 1489 (Part 2):2015. The product manual is intended for certification activities and for applicants seeking BIS certification.

The testing verifies the chemical and physical quality of calcined clay-based PPC against the applicable BIS requirements. It supports quality control and conformity assessment for cement intended for construction applications.

Calcined clay-based PPC is suitable for building construction and is used in applications such as foundations, mass concrete structures, dams, bridge piers, marine and coastal structures, highways and other infrastructure projects.
