19.08.2021The 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.

When making your own concrete it's important to use the correct concrete mixing ratios to produce a strong, durable concrete mix. Some basic mixing ratios for concrete are 1:2:3, 1:3:3, 1:2:4. These mixing ratios are based on the proportions of cement : sand : stone in that order. The ratio you use will depend on what psi strength you need.
