Vibrating Concrete Walls

Honeycombing occurs when concrete has.

Vibrating concrete walls. Reduce cold joints honeycombing and bugholes by training workers how to place and vibrate concrete in walls. Poured concrete can have problems that greatly affect the overall quality of the pour such as bug holes honey combing and cold joints. Area of influence for concrete vibrators. In concrete vibration external vibrators are electric or pneumatic concrete vibrators that mount to the exterior side of form work and cover a large area and usually you can space them 6 apart.

When vibrating a wall the important consideration is to make sure that all of the concrete is exposed to the vibration.

If problems occur however corrective action can minimize their recurrence.

One such a problem is honeycombing. Formwork vibration is commonly used in precast concrete construction and involves mounting the vibrators to the outsides of the concrete forms for larger pours the external form vibrators are often spaced 6 feet apart. The basic principles of placement and vibration are the same for any placing equipment used. Watch this video to see an example of how the area of influence of the vibration affects the concrete within the wall.

With surface vibration large vibrators sometimes called jumpers are directed manually onto the surface of the poured concrete. 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. In the construction industry there are many challenges regarding concrete quality. Problems that commonly occur when using shoring equipment are mitigated by use of a concrete vibrator which consolidates concrete and refines the pouring process.

One of the most important steps when pouring concrete is the consolidation or vibration of concrete. The use for external vibrators include floor to ceiling walls beam and one sided blind walls. Concrete vibrators if used properly will help consolidate concrete and will reduce the number of air pockets inside the concrete mass you can use internal vibrators or external vibrators depending on the application and where the concrete is being placed.
