OPC 43 :- The 43 grade OPC is the most popular general-purpose cement in the country today. The production of 43 grade OPC is nearly 50% of the total production of cement in the country. This OPC43 continues to gain strength after 28 days.
OPC 53 :- The 53 grade OPC is higher strength cement to meet the needs of the consumer for higher strength concrete. As per BIS requirements the minimum 28 days compressive strength of 53 grade OPC should not be less than 53 Mpa. Therefore, there is a vast difference in setting time of these cements. It sets very quicker and has low initial setting time. These types of cement can be used where rapid hardening is not needed.
