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 specialized works, such as pre-stressed concrete and certain items of precast concrete requiring consistently high strength concrete, 53 grade OPC is found very useful. 53 grades OPC produce 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.
+ Pre-stressed concrete components
+ Runways, concrete Roads, Bridges etc.
