What difference between OPC 43&53 cement. What will happen if use 43 OPC instead 53 OPC for M35.

Question

Accepted Answer

OPC 43 and 53 cement differ in their compressive strength. Using 43 OPC instead of 53 OPC for M35 concrete may result in lower strength.

OPC 43 cement has a compressive strength of 43 MPa, while OPC 53 cement has a compressive strength of 53 MPa.
The higher compressive strength of OPC 53 cement makes it more suitable for structural applications.
Using OPC 43 cement instead of OPC 53 cement for M35 concrete may result in lower strength and potentially compromise the structural integrity of the construction.
It is important to follow the recommended cement grade specifications to ensure the desired strength and durability of the concrete.

Accepted Answer

OPC 43 means that the cement is expected to reach a compressive strength of 43 MPa in a cube cast by 28 days. Similarly, OPC 53 reaches 53 MPa by 28 days. There is a contrasting difference in the setting times of these cements. OPC 53 sets quicker than OPC 43 and has a quite low initial setting time

Accepted Answer

Cement consumption is more.
