Compacting fresh concrete
1. Quickly immerse the vibrator head in the fresh concrete, hold it for several sec-
onds and slowly pull it out again.
2. Immerse the vibrator head in all areas of the formwork and compact the fresh
concrete.
Note:

Compact especially intensively in the area of formwork corners. In these areas,
the reinforcement rate is the highest.

Avoid contact of the vibrator head with the concrete reinforcement. The following
damages are possible if the vibrator head comes into contact with the concrete
reinforcement:

The connection of the concrete to the reinforcement can be lost.

The machine can be damaged.

The result of the compacting depends on the following points:

Holding time of the vibrator head in the concrete.

Diameter of the vibrator head.

Consistency of the concrete.

Reinforcement rate.
If you use a vibrator head with a smaller diameter, the compacting time to
achieve the same results as with a vibrator head with a larger diameter will in-
crease.

Indications that the concrete is sufficiently compacted:

The concrete no longer sets.

Air bubbles no longer or rarely rise.

The sound of the vibrator head is not changing anymore.
