عربىA flexible shaft concrete vibrator shakes freshly poured concrete to eliminate air bubbles, which weaken the finished product. Vibrators also consolidate the concrete to make it stronger and more durable.
Various applications for concrete vibrators include precast slabs, foundation work, and large precast concrete tables. It is important to ensure that the vibrator is used correctly to get the best results.
The portable vibrator is perfect for taking-anywhere jobs that require the vibration of slabs, footings, stairways and footpaths. It is powered by a genuine Honda 4-stroke motor and is easy to move around and use.
When using a vibrator, it is important to withdraw the head slowly. If you withdraw the head too quickly, it may not produce enough vibration to fully remove air bubbles.
For maximum effect, insert the vibrator into the concrete vertically or nearly vertically. Then withdraw an inch every second until the air bubbles are completely dissolved.
You should also make sure to penetrate previous lifts or layers of concrete before the vibrator is inserted into the current layer. This helps prevent cold joints, which can occur when insufficient bonding occurs between the new layer and the old one.
When a concrete vibrator is not used properly, it can cause structural failure and unevenness in the concrete surface. This is especially true in the case of internal vibrators, which are usually inserted at random intervals throughout the pour.
