What Is a Concrete Vibrator?

A Concrete Vibrator is a machine used for construction purposes in civil projects. Concrete Vibrators come in a variety of shapes and sizes. Some Concrete Vibrators are smaller, more efficient, and at battery power, while others are much larger with a primary power source based on electric power lines.

Choosing the right concrete vibrator can help resolve your concrete stability and long-term maintenance. Using Concrete Vibrator to help the concrete during settling period show a beneficial method that helps long-term durability of the concrete.

When wet concrete is poured, air bubbles become trapped inside the mixture forming cavities or spaces that look like honeycombs. If the air bubble is left untouched, “honeycombing” can jeopardize the longevity and strength of the concrete.

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.

Types of Concrete Vibrators:

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 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.

Different types of concrete vibrators are as follows.

• Internal Concrete Vibrator.
• Exterior Concrete Vibrator.
• Internal Gas Concrete Vibrator.
• Screed Concrete Vibrator.
• Rebar Shaker.
• Vibrating Table.

#1. Internal Concrete Vibrator-

Internal concrete vibrators have the best price and offer unparalleled mobility due to their size and weight. High-frequency concrete vibrators perform the power conversion of a single-phase into three-phase power, which is a beneficial feature due to the consistency of the power supply for large projects.

#2. Exterior Concrete Vibrator-

Exterior concrete vibrators can be a good choice for any vertical project, such as walls or other areas that require high reinforcement. Exterior concrete vibrators can also help reduce the mistakes that other types of internal vibrators can cause.

#3. Internal Gas Concrete Vibrator-

Internal gas concrete vibrators are obviously the best option when electricity is not available or poses a safety risk on the construction site. Internal gas concrete vibrators also work well in different areas such as curbing, gutters, and construction joints that require extra caution.

#4. Screed Concrete Vibrator-

Concrete vibratory screeds are an ideal, easy-to-use method due to the operator’s ability to remain standing in an upright position. Easy to use and reputation for lightweight makes Concrete vibratory screed a great choice for large or small projects, indoor or outdoor, such as patios, driveways, and indoor or outdoor basketball courts.

#5. Rebar Shaker-

The Rebar Shaker simply slipped over the top of the rebar, vibrates, and consolidates grout in 5 to 7 seconds. Tremendous savings in man-hours, from filling and refilling cells, clean-up, and lost time due to injury from slips and falls are realized through the use of the Rebar Shaker.

#6. Vibrating Table-

Concrete Vibrating Table is used for consolidating fresh concrete when forming cylinder and beam molds. The power cable to the vibrating table is user-supplied.

Concrete Vibrator Alternatives:

• Rebar shaker is another great Concrete Vibrator alternative to various traditional concrete vibrators.
• 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.
• Rebar shaker can be found in a wide range of sizes and can lead to significant savings in working hours and reduced cleanup activities. This tool will reduce the time it takes to pour concrete into a cell or a very tight space.

Advantages of Concrete Vibrator:

• The following are the Advantages of using a concrete Vibrator.
• The honeycomb structure caused by air bubbles can be avoided when using a Concrete Vibrator.
• A structure with heavy reinforcement can be easily compacted by using a concrete Vibrator.
• When Concrete Vibrator is used while constructing of a building, it becomes dense and waterproof.
• A low water-cement ratio can be used in construction when using a concrete Vibrator.
• The pace of work is increased when using a concrete Vibrator.
• A high aggregate cement ratio can be used when using a concrete Vibrator.
• When Concrete Vibrator is used while constructing a building, it improves the bond with reinforcement steel and gives greater strength to the building.
• When Concrete Vibrator is used while constructing a building, it provides a greater bond on construction joints which gives great durability to the building.
• A concrete vibrator reduces the amount of cement required by using dry mixes and improves the building finish.

Disadvantage of Concrete Vibrator:

• The following are the disadvantages of using a concrete Vibrator.
• When a concrete mix is ​​built with low workability, excess concrete vibration causes more energy consumption, which leads to energy dissipation.
• If the concrete vibrator is left on the concrete for too long, a water film will be on the concrete floor and the cement will often sink which results in lower strength on the concrete surface.
