Yes, shutter vibrator is relevant for a circular pier.

• Shutter vibrator is used to compact concrete and remove air voids.

• Circular piers also require proper compaction of concrete.

• Shutter vibrator helps in achieving uniform and dense concrete in circular piers.

• It ensures better strength and durability of the pier.

• Example: In the construction of a circular bridge pier, a shutter vibrator would be used to ensure proper com
