Power Concrete Vibrators Construction Vibrator Concrete Vibrator Electric Hand Held Cement Bubble Remover with 1M 1.2M 1.5M Hose (Color : 1m Rod, Size : 800w Hand-held Vibrator)

Product Information

Immersion-types are the most common type of concrete vibrator. As the name suggests, it gets immersed in the concrete in various locations, consolidating it locally. This concrete vibrator consists of a long, tube-shaped steel enclosure with a rounded tip, called a rod. Inside, a vibrating electrical element moves in an elliptical pattern at high frequency. Attached to a flexible electrical hose, which is, in turn, connected to an electrical motor, this unit is mobile and versatile. When pouring fresh concrete, some trapped air is inherent to the mixture. A concrete vibrator removes these air bubbles, consolidating the concrete in the process. Does vibrating concrete make in stronger? For standard 25-30MPa concrete with workability equal to 100-140mm slump, using a poker immersion vibrator, this amounts to about 3 seconds per inch of concrete depth. Immersion or Needle Vibrators are most commonly used vibrator for concrete. It consists of a steel tube (with one end closed and rounded) having an eccentric vibrating element inside it. This steel tube called poker is connected to an electric motor or a diesel engine through a flexible tube. They are available in size varying from 40 to 100 mm diameter. The diameter of the poker is decided from the consideration of the spacing between the reinforcing bars in the form-work.

The technology is similar to a standard concrete vibrator, but in this case, the Rebar shaker is slipped over the reinforcement bar and “shakes” or transmits vibration to the concrete.The length and depth of the civil project determine which type of concrete vibrator is right for use. There are many types of concrete vibrators, each with its own head size.

The Concrete Vibrators force the trapped air out of the mixture leaving the concrete to be more compact and level slab. It is not uncommon to see small air bubbles coming from the wet part of the concrete where the concrete vibrator is used properly. If the concrete mixture is designed with low workability, the over vibration causes additional power consumption, resulting in energy dissipation.The usefulness of internal concrete vibrators makes them the most widely used option available. Internal concrete vibrators are commonly used for commercial areas and projects undertaken by the Department of Transportation.
