What is 43 Grade CEMENT?
Ordinary Portland cement (OPC) is available in grades such as 33, 43 and 53. The compression strength of cement concrete after 28 days of setting will be measured to certify the cement grade. If you go for 43 grade cement, you will get compression strength of 43 mpa (mega pascals) in 28 days. 43 grade cement is used in general civil engineering construction work. Plastering, pointing, flooring, brick masonry and RCC work will be done very efficiently with 43 grade cement. The design strength of 43 grade cement will be of the order of 430 kg/sq cm.
The drawback with 43 grade cement is that it will attain strength slowly. However, it will attain the same strength that is attained with 53 grade cement after sometime. The hydration process in 43 grade cement will be slow. The heat release will be very less. Proper care should be taken to avoid micro-cracking. Ordinary and small scale consumers can go for 33 grade of cement also as per their needs.
