Understanding Concrete Grades . Based on strength, concrete is classified into different grades like M5, M7.5, M10, M15, M20 etc. In concrete grades, the letter "M" stands for "Mix" and the following number stands for characteristic compressive strength of concrete in 28 days in the Direct Compression test.
