Generally, the type of work adopted will decide the method of batching.
If we have small work of construction, then in that case volume batching adopted, otherwise weight batching adopted for large work.
1- volume batching- it should not be adopted for large work because it involves bulking of sand (or fine aggregate). And thumb rule says that the weight of sand having bulking is much less than that of no bulking having the same volume. So, in this case, there are more chances of theft. So it should not be generally preferred.
2- weight batching: it must be adopted for large work because of accurate batching quantity. Further, it doesn’t show the bulking problem.
The cement should be batched by weight only irrespective of the batching method.
**Conclusion: weight batching is more accurate and gives desired strength.
