The concrete vibra-
tor descends during
vibration inside the
concrete by its own
weight making verti-
cal penetrations to a
depth of 8 to 10 times
the diameter of its vi-
bratory head.
It is recommended to
introduce the vibrator
of about 10 to 15 cm
in the previous con-
crete layer to obtain a
better bond between
layers
When the bottoms of the frames are inclined
fill first with concrete to achieve a horizontal
surface and start to vibrate in the deepest part
of the structure.
Because the most powerful vibrations are gen-
erated at the tip of the head and decrease
towards the top, no increase in the vibrating
effect is obtained if the vibrating head of the
concrete is placed in a horizontal position.

It is recommended,
for more efficiency in
vibration work, not to
tilt the vibrator more
than 45 ° (45 ° maxi-
mum).
It is very important that when pulling the con-
crete vibrator out of the mix, this movement
is as slowly as possible to allow the space oc-
cupied by it to be now occupied by concrete.
• Never turn off the vibrator motor when it is
inside the concrete mix, always turn off the en-
gine when the vibrator is out of the concrete
mix.
• It is important that the vibrator head does
not intentionally strike the grille or rods, as the
contact with these materials decreases the life
of your vibrator.
• Never use your vibrator to transport the con-
3th Layer
crete sideways because it risks separating or
vibrating the mix.
• The recommended vibration time is 10 to 20
seconds per insertion.
IMPORTANT: Vibrating more time to a con-
crete mix does not provide better results, but
increases the risk of separation of the elements
that make up the mixture.
A simple way to realize that the
concrete is well vibrated is when
on the surface around the vibra-
tor head it looks shiny and no
air bubbles come out of it.
