Characteristic
43 Grade OPC.
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:

• General Civil Engineering construction work
• RCC works(preferably where grade of concrete is up to M-30)
• Precast 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. The physical and chemical properties of this cement are given in the table:

Comparison of Strength Characteristics of 43 Grade OPC
53 Grade OPC.
53 Grade OPC is a higher strength cement to meet the needs of the consumer for higher strength concrete. As per BIS requirements the minimum 28 days compressive strength of 53 Grade OPC should not be less than 53 MPa. For certain specialised works, such as prestressed concrete and certain items of precast concrete requiring consistently high strength concrete, the use of 53 grade OPC is found very useful. 53 grade OPC produces higher-grade concrete at very economical cement content. In concrete mix design, for concrete M-20 and above grades a saving of 8 to 10 % of cement may be achieved with the use of 53 grade OPC.

53 Grade OPC can be used for the following applications:

• RCC works(Preferably where grade of concrete is M-25 and above)
• Precast concrete items such as paving blocks, tiles building blocks etc.
• Prestressed concrete components
• Runways, concrete Roads, Bridges etc.
