The mix proportions ratio of concrete details the proportion of cement, sand and water it needs to make that particular strength of concrete. For example M20 grade of concrete is the mix ratio 1:1.5:3. The "1" is cement, "1.5" is fine aggregate and "3" is coarse aggregate. This mix applies to all grades of concrete.
