the best quality cement is to check for its grade. A grade determines the strength of 

the cement after 28 days of application. 33 grade, 43 grade, and 53 grade are the three 

grades of OPC used in India. The 33 grade cement means that the compressive 

strength of the cement is 33N/mm2 when tested as per Indian Standards under 

standard conditions. The other grades are also defined the same way.

 In that 3 grade of cement the most sutiable grade for 

high-rise building
