Which grade of OPC is best?

Ordinary Portland Cement (OPC):

Grade 33 refers to the cement attaining compression strength of 33 Mpa in 28 days of setting. This is same for 43 and 53 grades of cement. Grade 33 and 43 were used for construction in the past. As per IS standard code Grade 53 grade of cement is recommended for house construction.

Which is the best OPC cement?

Which cement is best 53 grade or 43 grade?

Which is better OPC 43 and OPC 53?

OPC 53 sets quicker than OPC 43 and has a quite low initial setting time. It is used in structures where rapid strength gain is required like large load bearing structures like bridges, huge buildings, etc. OPC 43 on the other hand doesn't set so quickly and has a normal initial and final setting time.

What is meant by 43 Grade OPC?

OPC 43 cement shall conform to IS:8112-1989 and the designed strength of 28 days shall be minimum 43 MPa or 430 kg/sqcm. Even though 43 Grade cements' early strength is less as compared to that of 53 Grade, with time it will attain the same ultimate strength as that of 53 Grade cement.

What is OPC 53 grade cement?

OPC 53 Grade cement is required to conform to BIS specification IS:12269-1987 with a designed strength for 28 days being a minimum of 53 MPa or 530 kg/sqcm. 53 Grade OPC provides high strength and durability to structures because of its optimum particle size distribution and superior crystallized structure.

What is OPC 33 grade cement?

33 Grade OPC cement

They are normally used for general construction purposes. 33 grade cement achieve 33N/mm² (Mpa) at its 28th day after casting. They are commonly used for making concretes which having low strength such as below M20 grade concrete. Note: 33, 43 and 53 are the grades of OPC cement.

Where is 43 and 53 grade cement used?

53 Grade OPC cement is Used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the criteria. 43 Grade OPC Cement is commonly used for plastering works, Non-RCC structures, pathways etc where initial setting time is not of importance.

Is 43 grade RCC cement good?

Unless a project requires very high strength cement, the use of 43 Grade OPC is generally recommended in general civil construction work such as residential, commercial and industrial structures. It is used in RCC works, preferably where the grade of concrete is up to M-30.

Which is better OPC or PPC?

PPC cement is generally used for plastering, brick masonry and waterproofing works. PPC has a lower heat of hydration and it is prone to fewer cracks compared to OPC. PPC has lower strength than OPC but PPC provides better workability and finishing than OPC. PPC provides greater resistance to chemicals.
