Products OPC Cement - 53 Grade Cement

53 Grade OPC Cement

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.
  • The physical and chemical requirements of 53 Grade OPC as per BIS Requirement are given in Table below
