What is a Concrete Vibrator?
A concrete vibrator is a machine used for construction-based purposes. These machines can come in several different shapes and sizes. Some are small and run strictly on battery power, while others are much larger with a primary power source stemming from electric power cords. Choosing the right concrete vibrator can help settle your concrete for long-term stability and maintenance.
Why Use a Concrete Vibrator?
Using vibration to assist concrete during its settling period has proven a worthwhile method that aids in long-term durability. As wet concrete is poured, air bubbles become trapped within the mixture creating cavities or honeycomb-like spaces. Left untouched, “honeycombing” can compromise the cement’s longevity and strength. Vibrators force the trapped air out of the mixture leaving the final product a more compact and level slab. It is not uncommon to see small bursts of air surfacing from the wet mixture when the vibrator is being used correctly.
What Kind of Concrete Vibrator Do You Need?
The length and depth of your project determines what vibrator is best for your needs. There are many types of concrete vibrators, each with its own head size.
The practicality of internal vibrators makes them the most commonly used choice available.
Internal vibrators are typically better priced and offer unparalleled maneuverability due to their size and weight. High frequency concrete vibrators perform a power conversion of single-phase energy into three-phase energy, which is a beneficial feature due to the power consistency it provides for large-scale projects. These vibrators are generally used for commercial sites and for projects done by the Department of Transportation.
External concrete vibrators are an optimal choice for any vertical project, such as walls or other areas that require maximum reinforcement. They can also be useful for downsizing mistakes that can be caused by other types of internal vibrators.
Internal gas vibrators are clearly the best option when electricity is either not available or presents a safety hazard on the work site. They also work well for distinct locations such as curbing, gutters and construction joints that call for additional precaution.
Vibratory screeds are a suitable, user-friendly option due to the operator’s ability to remain standing in an upright position. Ease of use and a reputation for being lightweight makes the screed a good choice for large or small, indoor or outdoor projects, such as patios, driveways, and indoor or outdoor basketball courts.
The value of using a concrete vibrator for your next project cannot be overstated. While there are many components to consider in order to achieve a positive end-result, this is certainly not one to ignore. The outcome of any concrete pour is highly dependent upon the use of proper tools and at what stage they are used along the process.
