Strength of Concrete vs Grades of Cement

To design a concrete mix of the desired strength with available materials, the strength of cement is required at 7 days (IRC:44-2008) 4 or at 28 days (IS:10262-1982) 5. Based on the strength values of cement, w/c ratio is directly read from the available charts given in IRC-44 & IS-10262.
