I think the answer is 10-25mm for vibration.

Low workability- (25mm-50mm) slump- light reinforcement requires mechanically operated vibrator.
Medium workability- (50mm-100mm) slump- standard reinforcement requires hand-operated vibrator.
Medium workability- (50mm-100mm) slump- standard reinforcement requires hand-operated vibrator.

The mechanical vibrator is powered by a motor. Whereas normal vibration is carried out by a human using rods of suitable dia.

25 - 50 mm = mechanical vibrator.

Vibrated concrete 12 to 25.

Slump value less than 25 mm -> power driven.
Slump value - 25 - 50 mm -> hand driven.
Slump value - 50 mm -> Mechanical vibrator.
Slump value - 100 mm -> Normal vibrator.
Slump value - 25 - 50 mm -> hand driven.
Slump value - 50 mm -> Mechanical vibrator.
Slump value - 100 mm -> Normal vibrator.

Right answer @Shiva.
It should be less than 25 mm for power driven vibrators.
And 25-50 mm for hand driven vibrators.
It should be less than 25 mm for power driven vibrators.
And 25-50 mm for hand driven vibrators.
