Price On RequestPortland Pozzolana Cement (PPC) is manufactured by blending
pozzolanic materials, OPC clinker, and gypsum either grinding them
together or separately. Today Portland Pozzolana Cement is widely in
demand for industrial and residential buildings, roads, dams, and
machine foundations. Pozzolana is an important ingredient in PPC which
is commonly used in the form of:
Fly ash
Volcanic ash
Silica fumes
Calcined clay
PPC is resistant to harsh water attacks and prevents the
formation of calcium hydroxide at the time of cement setting and
hydration. It withstands aggressive gases, thermal cracks, wet cracking,
etc. The BIS quality specifications for Pozzolana materials used in PPC
have been mentioned below:
Fly ash IS 3812:1981
Calcined clay IS 1344:1981
PPC is used in heavy load infrastructure and constructions
such as marine structures, hydraulic structures, mass concreting works,
plastering, masonry mortars, and all applications of ordinary Portland
cement.
The OPC 43 grade cement 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:
General civil engineering construction work
RCC works(preferably where grade of concrete is up to M-30)
Pre-cast items such as blocks, tiles, pipes etc
Asbestos products such as sheets and pipes
Non-structural works such as plastering, flooring etc.
The compressive strength of cement when tested as per IS code shall be minimum 43 MPa.
