Portland Pozzolana Cement (PPC)
The Portland Pozzolana Cement is a kind of Blended Cement
which is produced by either intergrinding 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.
Pozzolana is a natural or artificial material containing
silica in a reactive form. It may be further discussed as
siliceous or siliceous and aluminous material which in
itself possesses little, or no cementitious properties but
will in finely divided form and in the presence of moisture,
chemically react with calcium hydroxide at ordinary
temperature to form compounds possessing cementitious
properties. It is essential that pozzolana be in a finely
divided state as it is only then that silica can combine
with calcium hydroxide (liberated by the hydrating Portland
Cement) in the presence of water to form stable calcium
silicates which have cementitious properties. The pozzolanic
materials commonly used are:
Volcanic ash
Calcined clay
Fly ash
lica fumes
OPC is environment friendly as well as economical
Ordinary Portland Cement (OPC-53, OPC-43, OPC-33)
OPC-43 GRADE
The 43 grade OPC is the most popular general-purpose cement
in the country today. The production of 43 grade OPC is
nearly 50% of the total production of cement in the country.
The 43 grade OPC can be used for following applications:
