Compacting fresh concrete
1. Hold machine at the protective hose with both hands.
2. Quickly immerse the vibrator head in the fresh concrete, hold it for several
seconds and slowly pull it out again.
3. 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 ar-
eas, the reinforcement rate is the highest.
Avoid contact of the vibrator head with the concrete reinforcement. The fol-
lowing 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
increase.
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.
