Portland pozzolana Cement-Fly Ash Based. The Portland Pozzolana Cement is a kind of Blended Cement which is produced by either inter-grinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or grinding the OPC clinker, gypsum and Pozzolanic materials separately and thoroughly blending them in certain proportions.

The blended cement is made by grinding together approximately 55% of low-calcium fly ash, 45% of ASTM Type III Portland cement clinker, and a small amount of gypsum. This blended cement, being factory produced, would eliminate the cost of additional silos at the job site and result in a more uniform concrete.
