If you want to install concrete in a smooth and professional manner, an external concrete vibrator will do the trick. But you have to know how to use this tool correctly. You have to know the proper way of mounting it, the length of the vibration period, and the size of the area it needs to influence. An expert in concrete vibration will be able to help you choose the right vibrator for your project.
The style of concrete vibrator you choose will depend on the type of concrete you're using. For example, internal vibrators are more suitable for simple applications where you don't need perfect surface quality. On the other hand, an external vibrator will be more suitable for applications with rebar or large concrete pieces. Also, different vibrators have different frequencies and amplitudes. For instance, a high-frequency, low-amplitude vibration is suitable for stiff concrete and high-mortar mix.
There are two main types of external concrete vibrators. The first type uses a high-frequency motor with a speed range of 6000-12000 rpm. This type is usually used in areas without a three-phase power supply. The second type uses a DC motor and an aluminum housing. It can be used on conveying equipment or in prefabricated buildings.
When using an external concrete vibrator, it's important to ensure that the concrete is fully mixed and agitated. Otherwise, excess vibration can cause structural failures. It can also affect the final product's sheen. In addition, excessive vibration may cause the aggregates and water to separate.
