OPC43 grades are majorly used for wall plastering works, Non-RCC structures, pathways, etc. Things to be kept in mind that 43 cement brand follows to IS 12269 standard code. (OPC)43-grade cement achieves a compression strength of 43 Mpa (megapascals) in 28 days of setting.
2. Ordinary Portland Cement (OPC)53 Grade Cement:
OPC53 grades are used in RCC, cement grouts, instant plugging mortars and other construction works with pre-stressed concrete of higher grades. This grade of cement is used for fast-paced construction where you can achieve quick initial strength. 53 Grade attains 27 Mpa in 7days. 53 Grade cement follows to IS 8112 standard code.
Difference Between 43 Grade OPC cement and 53 Grade OPC Cement
43 Grade Cement
53 Grade Cement
After 28 days of setting, 43 grade cement has a compressive strength of 43 N/mm2 or 43 MPa.
After 28 days of setting, 53 grade cement reaches a compressive strength of 53 N/mm2 or 53 MPa.
After 7 days, cement grade 43 reaches 23 MPa.
A compressive strength of 27 MPa after 7 days is achieved by 53 grade cement, which sets more quickly.
Grade 43 cement is comparatively less finer than Grade 53 cement.
OPC 53 Grade Cement is finer than grade 43 cement and has clinker grinding to the fullest extent.
Uses & Application
Where initial setting time is not a major consideration, 43 grade cement is used in basic civil engineering construction work, RCC structures (up to M25 concrete), non-RCC structures, plastering operations, flooring, walkways, and asbestos products such as sheets and pipes.
Because cement of grade 53 cement sets more quickly, it is used in construction projects that call for earlier strength development, such as reinforced concrete structures (ideally where the concrete's grade is M-25 and above), cement grouts, higher-grade prestressed concrete structures, bridges, concrete roads, and instant plugging mortars.
The prices of this cement can vary from brand to brand. Normally 43 grade cement is 3-4% cheaper than 53 grade OPC.
Normally 53 grade cement is costlier than 43 grade cement.
