Difference between 43 Grade Cement and 53 Grade Cement

Ordinary Portland Cement (OPC) is graded according to their strength. The grade indicates the compression strength (Mpa) of the concrete that will attain after 28 days of setting.

Compression Strength:

Cement grade indicates the compression strength of the cement concrete after 28 days of setting. 43 Grade Cement attains compression strength of 43 Mpa (megapascals) in 28 days of setting compared to 53 Mpa attained by 53 Grade cement.

Initial Strength:

53 Grade cement is used for fast paced construction were initial strength is to be achieved quickly. 53 Grade cement has fast setting compared to 43-grade cement. 53 Grade attains 27 Mpa in 7 days compared to 23 Mpa by 43-grade cement.

Uses & Application:

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.

Prices:

53 grade cements are 2-3% costlier compared to 43 grade cements.

Brands:

Birla Cement, Ultratech Cement, ACC Cement, Zuari Cement, Coromandel Cement, Ramco Cement, Dalmia Cement are some of the well-known brands in Southern India.
