Manual vs Machine Concrete Mixing

[tendlu]

Hello,

Is it OK to do manual mixing of concrete for the columns? In other words, is there any downside to doing manual mixing as opposed to doing machine based mixing?

Please comment.

There will be slight variation of concrete ratio when doing a manual mixing , but that is 'ok' when it comes to column - is what I have observed.
most people go for machine mixing - when it involve large quantity/area
