This is a tool which will create vibrations so that concrete mixture will be settled properly. by using this you can avoid air gaps in the concrete mixture. Mostly used at the time of molding and pillar construction.
Vibrator plays a vital role at the time of molding. In the below picture vibrator is not used for some portion of the beam. Vibrator will remove all the air bubbles and helps in making strong concrete.
molding was not properly done.
If you are constructing pillars there should not be any gaps. Concrete has to be packed properly. so after placing the concrete mixture mason has to use this instrument to pillars and beams
So always insist to use vibrator for pillar, beam and molding purposes.
