Vibrating A Concrete Wall

The basic principles of placement and vibration are the same for any placing equipment used.

Vibrating a concrete wall.

You will save time and money by using external concrete vibrators. Vibco concrete vibrators vibrate all types of concrete forms to provide exceptional consolidation and finish quality. Vibration every 15 minutes can prevent concrete from setting as quickly so that concrete bonds together until fresh concrete can be obtained to continue the pour. Vibrating is a critical step on many concrete construction projects.

Vibrators work by allowing air to float up and out of the concrete so the tip should not be withdrawn faster than the air can move upward about 3 inches per second. Honeycombing occurs when concrete has. If the wall is poured in multiple lifts the vibrator tip should go deep enough to penetrate 3 to 6 inches in the previous layer. One such a problem is honeycombing.

Using admixtures minimizes segregation.

Concrete sets up in about an hour and a cold joint is formed between the fresh concrete and the more hardened concrete weakening the overall structure. Reduce cold joints honeycombing and bugholes by training workers how to place and vibrate concrete in walls.

When concrete is poured it might have hundreds or even thousands of air bubbles which can substantially weaken the concrete structure. When vibrating a wall the important consideration is to make sure that all of the concrete is exposed to the vibration. For thin walls where an insertion at the center of the wall would be sufficient to reach both walls a good rule of thumb would be to choose a vibrator with a radius of influence equal to 3 4 the total thickness of the wall. If problems occur however corrective action can minimize their recurrence.
