What are the raw materials used for the production of Portland pozzalana cement?What are the main stages of manufacturing Portland pozzalana cement?
The raw materials required for manufacture of PPC are OPC clinkers with 10 – 25 % of Pozzolanic material. The Pozzolanic material used are calcined clay (IS: 1489 part II of 1991) or fly ash (IS: 1489 part I of 1991).
The main stages of manufacturing Portland pozzalana cement are:-
