· Compaction of concrete or Vibration of concrete can be performed in five different methods they are. Vibrating the concrete internally by inserting an internal vibrator into concrete mass. Vibrating the concrete while fixing the shuttering using Shutter formwork vibrators. By Vibrating the entire mass of concrete using a vibrating table.

· If you work with concrete, here’s why you need a concrete vibrator: Improved strength: The better you compact your concrete, the denser it will be. Vibrating concrete gives it a higher compressive strength, which creates more durable concrete. Remove air: When you pour concrete, air bubbles can get trapped inside.
