Describe the hand mix process of concrete on the floor?

Let’s discuss some important precautions that we should keep in our mind while doing hand mixing of concrete. They are as follows ;

• Hand mixing should be used for small concrete preparation
• Hand mixing platform should be watertight and it should be impervious
• Mixing platform should be of concrete platform or brick floor to avoid the addition of extra water in our concrete
• Water should be added in some interval in concrete while hand mixing
• Avoid large sizes of buckets for the measurement purpose
• Labours should wear a mask to avoid some respiratory diseases

Steps to follow for doing hand mixing of concrete :

• Doing proper batching of all the ingredients of concrete and spread them evenly
• Add cement with Sand and mix them for throughout
• Mixing process should continue until we get the homogeneous colour
• Then add coarse aggregate into it and again mix it appropriately
• For mixing forward and backward movement of shovel have to be done
• Then at the centre, one hollow circular space is formed for the addition of water
• While doing hand mixing 5 to 10% of the extra amount of cement should be added
• PPE( Personal Protective Equipment) should be wear by labour while doing hand mixing
