RubberHeadTM
Oztec's "High
Efficiency RubberHeadTM" 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 "RubberHeadTM" 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 "RubberHeadTM" 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 RubberHeadTM":
- 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 "RubberHeadTM"
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 "RubberHeadTM"
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.
