Different grades of Cement:
No matter whats the brand of cement is, There are three different grades of Ordinary Portland cement which are available in the market.
- 33 Grade
- 43 Grade
- 53 Grade
33 Grade of Cement:
As per Indian Standards, IS 269 – 2015, 33 Grade of cement means the Compressive Strength of cement after 28 days is 33N/mm2. This grade of cement is outdated and no one is using in recent times. 33 Grade of cement is not suitable for making more than M20 grade of concrete.
43 Grade of Cement:
As you already know 43 grade of cement means the Compressive strength of cement when tested under the CTM is 43N/mm2 as per Indian Standards, IS 8112 – 2013. Concrete of grade upto M30 grade can be made using 43 grade of cement
53 Grade of Cement:
This is the high grade of cement where anyone can easily buy from the market. The Strength of cement having the Compressive strength of 53N/mm2 is called 53 grade of cement. The setting time of cement is quicker when compared with the 33 and 43 grade of cement. Any grade more than M25 is easily achievable by using 53 grade of cement.
