Concrete grades based on different international codes

Oct 24, 2018  Different concrete grades based on different international codes. The concrete grades are normally indicated as M30 or C30 or C30/37 and so on depending on the code. The alphabet ‘M’ or ‘c” refers to it as a ‘Concrete Mix’ and the number that follows indicates the characteristic strength of that that mix in MPa at 28 days.

Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.
