Different Grades of Cement and its importance

Grade of Cement:-

There are different grades of cement, Grade of Cement is nothing but the strength of cement (How much strength a person has to lift a weight, is same related to the How much Strength does cement can yield or bear.) 

We all know that the cement is the primary ingredient of the concrete which means the strength of cement is directly proportional to the strength of concrete. So, one should have enough knowledge about the grade of cement and how it affects the construction. 

The grade is the metric to measure the strength of cement. There are different grades of cement. The strength of cement increases as the grade of cement increases.  Fineness of cement increases with the increase of grade. Grade of cement is chosen as per the one requirement and type of work.

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. 

  1. 33 Grade 
  2. 43 Grade 
  3. 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 This grade of cement is outdated and no one is using in recent times. 33 Grade of cement is not suitable for making more than M20 grade of concrete.

Where to use 43 grade of cement?

This type of cement is used in making Plain Cement Concrete (PCC) and for plastering the walls, brickwork mortar, Precast items like tiles, Cement pipes.

Compressive Strength of 43 Grade Cement is 43N/mm2.

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.
