Will you use external concrete vibrators?

Industrial & Manufacturing Blog

Concrete is one of the most versatile building materials available. Perhaps you have been thinking about using concrete in the foundations of your new structure or, maybe, you want to use precast concrete formwork as a part of your structure. Whatever your concrete needs may be, one thing that you must know is that concrete must be thoroughly vibrated to remove the air bubbles and ensure that it is consolidated. When you want to vibrate concrete, you must choose between internal concrete vibrators and external concrete vibrators.

Internal or external

There are many occasions when you should place the concrete vibrators directly into the concrete, but there are other times when it is best to use external concrete vibrators. External concrete vibrators have several advantages that you may not have considered. Internal vibrators tend to only consolidate the area where they are placed. This means that with internal vibrators, it can be difficult to consolidate any inaccessible areas. When you use external concrete vibrators fixed to the outside of the formwork, the concrete is consolidated as a mass.

Creating a good quality finish

Another reason to consider using external concrete vibrators is when you need a particularly good quality finish. If you don't want to carry out further processing on the concrete after consolidation, external concrete vibrators are the right option for your project. External vibrators are often the fastest and most precise way to achieve the right level of consolidation but you must select the best vibrators and vibration frequency for the thickness of concrete have. If you aren't sure which external vibrators to choose, your supplier can explain the different vibrator speeds and how they could be used on your project.

Attaching external concrete vibrators

If you decide to use external concrete vibrators, you must ensure that the vibrators are attached firmly to the formwork with the appropriate equipment. Your supplier should provide the needed clamps and other fastening equipment with the vibrator, but if you aren't sure that you have what you need, always ask. It is better to ask what might appear to be a silly question than to make a mistake that could end up setting back your project by weeks. While vibrating concrete isn't especially complex, it's important to get it right as it affects the strength and durability of whatever you are building. Your supplier can answer any questions that you have and ensure that you leave their premises with the best vibrators for your project.
