In this article, we will discuss the difference between 33, 43, and 53-grade cement.

 

  1. Introduction  

The grade of cement refers to the compressive strength obtained by cement after the curing of 28 days.

 

  A. 33-Grade Cement  

The grade of cement that has a compressive strength of 33 N/mm² is known as 33-grade cement.

 

  B. 43 Grade Cement  

The grade of cement that has a compressive strength of 43 Mpa, 28 days after casting is known as 43-grade cement.

 

  C. 53 Grade Cement  

55-grade cement has a compressive strength of 55 N/mm² tested after curing for 28 days.

  2. Difference between 33, 43 and 53-grade cement  

The difference between 33, 43 and 53-grade of  cement is discussed below;

 

         33 Grade           43 Grade           53 Grade
Its compressive strength is

3 days=16 N/mm^2

7 days=23N/mm^2

28 days=33N/mm^2

Its compressive strength is

3 days=22N/mm^2

7 days=33N/mm^2

28 days=43N/mm^2

Its compressive strength is

3 days=33N/mm^2

7 days=43N/mm^2

28 days=53N/mm^2

Initial strength is lessThe initial strength is medium. Initial strength is high.
The strength of 43 Grade will increase even after 28 days.The strength of 43 Grade will increase even after 28 days.The strength of cement does not increase after 38 days.
Used for general construction work under normal environmental conditions.Non-structural works like flooring, plastering, etc.Used where higher strength is required like Runway RCC work, concrete bridge, etc.
