Mix ratios, consisting of cement, sand, and coarse aggregate, vary across different grades of concrete. For example, M20 grade concrete has a mix design ratio of 1:1.5:3, while M15 grade concrete has a mix design ratio of 1:2:4. Higher-grade concrete generally requires a greater proportion of cement to achieve its desired strength.
