Grades of Cement

43 Grade Cement

53 Grade Cement

Compressive Strength

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.

Initial Strength

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.

Fineness

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.

Price

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.
