One of the most important, albeit lesser known, tools for construction projects is the concrete vibrators. But, why exactly do you need these devices in the field?
For one, concrete vibrators are a building code requirement. So, it is no wonder that there are concrete vibrators for sale online and in shops. Also, these tools give a smooth finish to surfaces. They work by vigorously shaking freshly poured concrete to eliminate thousands of air bubbles, preventing the material from forming weakly.
Here are the common types of concrete vibrators:
These are the most commonly used vibrators and known as immersion, poker, or needle vibrators because of a flexible tube attached to their power units. They come in different sizes, so they are ideal for most applications. More importantly, the power can be provided by an electric motor, compressed air, or petrol engine.
Mostly used in thin, congested sections, form vibrators are also called as external vibrators. They are attached externally and may be shifted as the process progresses. However, this method of vibration can be more costly as they consume more power than the other types of vibrators.
Typically placed directly on the concrete mass, surface vibrators are ideal for shallow surfaces (with a depth not more than 250mm). In addition, they work best for very dry mixes.
Vibrating tables are a perfect tool when you’re dealing with harsh and stiff precast concrete mixes. Made of rigid steel platforms on steel plates, the vibrating tables are durable and can be powered by electric motors.
Yes, a few shakes here and there can make a whole lot of difference in a construction project. With the right type of a concrete vibrator, surfaces can be as smooth and as strong as it should be.
