Good Vibrations
Vibrating Pokers
The application of vibration by mechanical means is a long recognised method of improving the structural integrity of mass poured concrete.
How do Concrete Vibrating Pokers Work to remove Air from Concrete? The vibrating action of the head causes the surrounding concrete to vibrate. As the aggregate and cement slurry of the concrete vibrates the mix becomes more fluid. This allows air that will have been trapped in concrete during the mixing process to form bubbles that then rise to surface, out of the concrete resulting in the desired smooth finish.
Why Vibrate?
- Ensures greater durability & a smoother finish
- Reduces incidence of honeycombing and surface air voids
- Vibration gives greater density
- Compressive strength is increased buy the removal of entrapped air
- It improves bonding with reinforcing steel and at construction joints
