Different Methods for Mixing Concrete - Gharpedia.com
Hand mixing is a cheaper method of mixing concrete but recommended only for very small works. Proper mixing of material is achieved in machine mixing only and hence used for big projects. Ready mix concrete requires less time as compared to site mixing (hand or machine mixing) and quality of concrete is also better than the site mixing.
Mixing Of Concrete - Hand Mixing And Machine Mixing
In this method of mixing, about 10% more cement is used to make good the cement lost due to possible water flowing out of the mix and also to make good strength characteristic to inferior result of hand mixing. 2. Machine Mixing: On large works where concreting work is quite large, machine mixing of concrete proves economical.

Batching, Mixing, Placing and Compaction of Concrete
Methods of Compaction of concrete Vibration: To compact concrete you apply energy to it so that the mix becomes more fluid. Air trapped in it can then rise to the top and escape. As a result, the concrete becomes consolidated, and you are left with a good dense material that will, after proper curing, develop its full strength and durability.
