RECOMMENDATIONS OF USE OF CONCRETE VIBRATOR
1. Choose the right size of poker for: the size of the job, the spacing of reinforcement, slump of the concrete and the mix design.
2. It is recommended to have an additional concrete vibrator available.
3. Pour the concrete evenly, into the form work, in 300-500 mm thick layers.
Do not use the poker vibrator to spread the concrete.
4. Vibrate the concrete systematically. Make 300-500 mm vertical insertions at
intervals of 8 - 10 times the tube diameter. Where possible, push the poker
vibrator about 150 mm into the previous layer of the concrete, this will help obtain
the best level of bonding between the two layers.
The concrete has been thoroughly vibrated when the surface around the poker
is shiny and no large air bubbles rise to the surface of the concrete. This normally
takes 10 - 20 seconds at each location of the poker.
5. Withdraw the poker slowly so that the concrete can ow into the void left by the
poker.
6. Do not push or force the vibrator against the reinforcement. Keep a distance of
70 mm minimum from the walls.
7. Always remove the poker vertically, so the concrete lls the empty space again.
Do not switch off until the poker is withdrawn. The speed of removal is approximately 80 mm per second. When the vibrator is
almost out, extract quickly to avoid shaking the surface.
Do not keep the concrete vibrator out of the concrete during long periods. If you have stopped vibrating

the concrete, turn the poker off.
