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 less | The 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. |
