Oztec's "High
Efficiency RubberHead" Outperforms any other type of vibrator
Epoxy coated rebar presents a particularly
troublesome problem. Steel heads act like an electric hammer, striking any
rebar or forms they contact, over 10,000 times per minute, with a force
from hundreds to over 2,000 pounds per blow. Contact with a steel vibrator
head of as little as one second can chip enough coating to subject the
steel to deep rust. Oztec's patented High Efficiency "RubberHead"
vibrator head not only meets DOT non-metal head specifications for
protecting coated rebar and expensive forms, but exhibit some very special
and unique properties. The High Efficiency "RubberHead" urethane
dimpled construction sends strong shock waves off the entire length of the
head, with a larger radius of action, producing denser concrete with less
voids to patch.
Oztec's patented
"High Efficiency RubberHead":
| • |
Will
outperform any other type of vibrator…round, square, hi-cycle,
etc…Any Type! |
| • |
Will
protect epoxy coated rebar and expensive forms. |
| • |
Is
outstanding in low slump (to "0" slump) concrete. |
| • |
Essential
in large pours of very stiff concrete. |
| • |
Makes
concrete denser with less voids to patch. |
| • |
Vibrates @
12,000vpm, never drops below 10,500vpm when lowered deep into low
slump concrete. |
| • |
Provides
Superior Action. |
| • |
Is an
absolute must for Architectural concrete where cosmetic surfaces
are essential. |
| • |
All Oztec
vibrators meet or exceed ACI specification # 309 |
Why the Oztec
"RubberHead" outperforms any other type of Vibrator.
(a.) When a smooth vibrator head (round, square or any other shape) is
lowered into a relatively stiff concrete batch, the front or nose of the
vibrator drills a hole. It pushes away concrete faster than it can return.
Result, shock waves produced mostly from the vibrator's front end.
(b.) Oztec's patented "RubberHead"
has a large number of openings which allow wet concrete to cool the inner
shell. These openings act like "suction cups", which keeps
concrete in contact with the entire length of the vibrator head, sending
strong shock waves into the mass.
