عربىAn internal concrete vibrator is a tool used to remove air pockets from concrete. Before the concrete hardens, vibration helps reduce voids and improves the overall quality of the final product.
The vibration of the concrete can be done with an internal or external vibrator. Internal vibrators are better suited for applications where the vibrator needs to be used on multiple forms. A single internal vibrator can be placed at regular intervals throughout the concrete.
When choosing a concrete vibrator, make sure you choose the right model for the job. Some models are powered by gasoline, and others are operated by electricity. There are also hand-held models for smaller jobs.
You can purchase a high speed internal concrete vibrator for pre-fabrication. This is a great choice for vertical projects. It can have a rated power of up to 1000W. However, you will need a voltage match and a power cable.
To properly use an internal concrete vibrator, it must be inserted into the concrete at an interval of six inches. This can vary depending on the depth of the concrete member.
Vibrating the concrete can also help eliminate voids. The area affected by the vibrator is a factor in the amplitude of the vibration. If you need a higher frequency, you may need a larger diameter internal concrete vibrator.
You will want to check the vibration time on your concrete vibrator. Vibrating between five and fifteen seconds will help minimize voids and bug holes.
