What is the difference between 43 grade and 53 grade cement?
Here are the major difference between u201c43 gradeu201d and u201c53 gradeu201d cement: OPC 43 Grade Cement 43-grade cement means that the compressive strength of the cement after 28 days is 43N/mm2 when tested as per Indian Standards under standard conditions. This grade of cement is used for plain concrete work and plastering works.43 grade cement is also used to make precast items, such as tiles, blocks, pipes, etc. It can be used where setting time is not a necessary criterion. OPC 53 Grade Cement It is a strong cement where 53-grade means that the compressive strength of the cement after 28 days is 53 N/mm2 when tested as per Indian Standards under standard conditions. 53-grade cement has a fast setting time as compared to 43-grade cement. This grade of cement is not used for ordinary works. It is mostly used for structural purposes as in reinforced cement concrete.
