53 Grade of cement
53 Grade of cement :
The 53 grade of cement is used for general civil construction works which is under normal expose(environmental) conditions. the average compressive strength of cement mortar attained after 28 days (6724 hours) in mega pascals (Mpa) of at least three mortar cubes of face area ( 50 cm squared) composed 1 part of cement and 3 parts of sand(conforming to IS 12269) by mass and P/4 (P is the percentage of water required to produce the past of standard consistence as per IS standards) + 3 percentage( of combined mass of cement plus sand )of water,prepared, stored and tested.
53 Grade OPC is a higher strength cement to satisfy the requirements of the buyer for higher strength concrete. As per BIS requirements the minimum 28 days compressive strength of 53 Grade OPC shouldn't be less than 53 MPa. For certain specialized works, like 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 you look after cement may be achieved with the utilization of 53 grade OPC.
-
53 Grade OPC will be used for the subsequent 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.
