The first letter in grade “M” is the mix and 30 is the required strength in MPa. Based on various lab tests, the grade of concrete presence in Mix Proportions. For example, for M30 grade, the mix proportion can be 1:1:2, where 1 is the ratio of cement, 1 is the ratio of sand and 2 is the ratio of coarse aggregate based on volume or weight ...
Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. 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.

When we teach mix design courses, the most frequent comment we get is, “Just give me a mix design.” To do so would be regarded as improper, foolish even. No one does this because a successful concrete mix design at one plant will not always work at another. All concrete is, and always should be, considered localized to a specific manufacturer.
