Difference Between 43 Grade Cement And 53 Grade Cement

There are different types of cement used in construction works. Ordinary portland cement is the most widely used cement among them. Portland cement is graded according to their strength where the grade denotes the compressive strength of concrete that will achieve after setting of 28 days in MPa (Mega Pascals) or in N/mm². Ordinary portland is graded 33, 43, and 53. In this article, we will discuss the difference between 43 and 53 grade cement.

Difference Between 43 Grade Cement And 53 Grade Cement:

Both types of cement are good having their own advantages. But there are some differences in properties and strength. Read the complete article to get an idea of which cement is better.

Compressive Strength:

The number 43 and 53 indicates the compressive strength of cement. Their grade difference indicates their strength difference. The strength is determined by the compressive strength test and consistency of standard cement paste.

The compressive strength of 43 grade cement is 43 N/mm² or 43 MPa after 28 days of setting and the compressive strength of 53 grade cement is 53 N/mm² or 53 MPa after 28 days of setting.

Initial Strength:

53 grade cement has a faster setting having a compressive strength of 27 MPa after 7 days but 43 grade cement gets 23 MPa after 7 days.

Fineness:

There is not much difference in composition. Only OPC 53 grade cement has the grinding of clinkers to the maximum extent and this cement grade is finer than grade 43.

Uses And Application:

As cement of 53 grade cement has a faster setting, it is used where earlier strength development is required such as reinforced concrete structures (preferably where the grade of concrete is M-25 and above), cement grouts, prestressed concrete structures of higher grades, runways, concrete roads, bridge, sinstant plugging mortars, etc.

43 grade cement is used in general civil engineering construction work, RCC structures (up to M25 concrete), non-RCC structures, plastering works, flooring, pathways, asbestos products such as sheets, and pipes. etc where initial setting time is not a prime factor.

Price:

Well, the prices of this cement vary from different brand to brand. Normally 53 grade cement is 3-4% costlier than 43 grade OPC.

    • It can be used but setting period is slow as described..But it’s not that 43 grade don’t use in r c c structure…

  1. My house ground level is at level of road. I have a thought of raising the building. Whether it is good to lift the building to achieve the height from the road?
