10. OPERATION RECOMMENDATIONS
10.1 Choose the type of vibrator adequate to the dimensions of the structure, the distance
among the reinforcement, and the slump cone. It is recommendable to have an additional
concrete vibrator, based on the scope of your project.
10.2 Before beginning the job, check that the concrete vibrator is in good use and it works
correctly. Use safe practices and protection.
10.3 Pour the concrete in the structure, avoiding high heights. Try to pour levelled the
concrete. The thickness of every layer should be less than 50 cm. Between 30 and 50cm is
recommended.
10.4 Introduce the vibrator vertically in the concrete mass without moving it horizontally.
10.5 Do not use the vibrator to push the concrete horizontally.
10.7 The concrete vibrator should be introduced into the mass at regular intervals.
10.7.1 Intervals should be from 8 to 10 times the diameter of the poker.
10.7.2 Watch the concrete during the process of vibrating to determine the field of action
of the vibrator. This field should be overlapped to avoid areas without vibrating.
10.8 To obtain optimum compacting, plunge it 10 cm into the precedent layer to assure a
good adherence. Different layers should not be big to avoid cold joints while vibrating.
10.9 Do not push or force the vibrator into the mass, as it could be stuck in the reinforce-
ments.
10.10 The time of vibration in each point depends on the type of the concrete, the size of
the vibrator and other factors.
10.10.1 This time can be from 5 to 15 seconds aer the immersion in each point.
10.10.2 The time is shorter for a fluid mass, a vibration in excess can produce segrega-
tion.
10.11 Well vibrated concrete creates a shiny and compact surface around the poker. There
should be no more air bubbles, as well a change in the noise of the vibrator is produced.
10.12 Many flawed structures are produced due to the vibration performed in an disorder-
ly, rushed manner.
10.13 DO NOT push or force the vibrator against the reinforcement.
10.13.1 Keep a minimum distance of 7 cm from the walls.
10.14 Always remove the poker vertically with movements upwards and downwards so the
concrete fills the empty space again.
10.15 DO NOT switch off until you stop the vibration completely.
10.16 The speed when removing the vibratpr should be approximately 8 cm per second.
When the vibrator is nearly out, extract quickly to avoid shaking the surface.
10.17 In order to vibrate slabs, the poker has to be kept at an angle.
10.18 DO NOT keep the concrete vibrator out of the concrete during long periods of time.
10.19 If you do not continue vibrating, turn off the unit.
10.20 Always follow the maintenance and safety instructions.

11. TIPS AND SUGGESTIONS FOR VIBRATION CONCRETE
Proper concrete vibration techniques WILL:
• Produce concrete with the maximum strength and qualities designed in the mixture.
• Bond rebar to maximize concrete strength.
• Slow down the penetration of rust-causing liquids by increasing density.
• Eliminate rock pockets and li lines.
• Minimize patchwork, improving surface appearance by removing trapped air.
Proper concrete vibration techniques WILL NOT:
• Cause segregation.
• Eliminate a significant amount of entrained air.
• Normally damage the lower layers, as long as the concrete in these lower layers
becomes plastic under the vibrating action.
For quality concrete results, we recommend the following:
1. Select the largest concrete vibrator that is suitable for the job at hand.
2. Insert the concrete vibrator vertically. Using it’s own weight, allow it to sink to the
desired depth.
a. DO NOT FORCE, as it may lock in between rebars.
3. Hold the concrete vibrator for 5 to 15 seconds. Then, slowly li it up, remaining behind
the trapped air’s upward movement.
a. Allow around 15 seconds for each 2-foot distance to avoid re-trapping the air.
4. To close the hole formed by the vibrator, move it up and down slightly.
5. To prevent churning air into the top layer, withdraw the vibrator quickly when near the
top.
6. Move the vibrator and re-insert it at a distance of 1 ½ X the “Radius Of Action”. (Shown
in diagrams on page 19)
7. Allow the vibrator to pass 3 to 6 inches into the previous layer. This knits the layers
together, ensuring a strong bond and preventing “li lines” when the forms are removed.
8. Try to limit concrete pours to 2 to 3 feet high. This way, air has less resistance to
escape.
9. DO NOT use the vibrator to move the concrete laterally, as it causes segregation.

11. TIPS AND SUGGESTIONS FOR VIBRATION CONCRETE CONTINUED
Consolidation eliminates the pockets of aggregate and air bubbles. This maximizes
strength and eliminates surface voids, bringing sufficient fine material to the surface and
against forms to produce the desired finish.
Concrete vibrators consolidate concrete by sending out shock waves, which allows aggre-
gate to float freely while pushing lighter trapped air up and out of the mixture.
They allow pouring stiff mixtures of concrete possible. Stiffer mixtures are stronger, more
economical, result in less segregation, less bleeding, and less shrinkage cracks.
When you have consolidated concrete properly, a thin line of mortar will appear along the
form near the vibrator, or the coarse aggregate will disappear into the concrete.
For more information regarding vibrating concrete, refer to publications from the American
Concrete Institute.
