Approximately 15 to 30% of ordinary Portland cement is replaced with fly ash in Portland pozzolana cement.
The compressive strength of Portland pozzolana cement is more for long term use compared to ordinary Portland cement.
Ordinary Portland cement is one of the widely used cement.
For residential construction, we prefer Portland pozzolana cement as compared to ordinary Portland cement. We use ordinary Portland cement only for commercial purposes.
Three grades of cement are available 33, 43, and 53.
33 grade of cement means the compressive strength of cement after 28 days of curing should be at least 33 mega Pascal not more than that value.
43 grade of cement was the compressive strength of cement after 28 days of curing should be at least 43 Newton per mm square or more than that.
Similarly, 53 Grade of cement means compressive strength of cement after 28 days of curing should be at least 53 Newton per mm square or more than that value.
Thank you.
