whether PPC or OPC is preferable for the construction of elevated water storage tank
Satish:
PPC (Portland pozzolana cement) is preferred over OPC (Ordinary Portland cement) for water storage applications [1].
The fly ash used in PPC helps with handling the thermal strain that occurs in large masses of concrete used in dams. As a result there is less cracking and the final product is more impermeable to water intrusion.
