Epoxy Coated Rebar Damage
  Oztec's "High Efficiency RubberHead™" Outperforms

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 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.

RADIUS OF ACTION
The most important bit of information needed for complete consolidation.
Radius of Action is the distance from the center of the vibrator to the outer edge, where complete consolidation takes place (see diagram). For quality concrete, Oztec lists conservative values for "Radius of Action". Complete consolidation is necessary for low slump concrete with close meshed reinforcement bars, high strength concrete, and architectural concrete. Radius of Action can be twice the listed values when slump is high or super plasterizers are used. It is important these values are used only as a general guide. Specifications are subject to change.
