What is the effect of concrete vibrations?
Concrete vibrations should be based on the length of the vibrating rod and the effective radius of the vibration, the order of layered vibrations, vibrating rods moving distance can generally be about 40cm (small cross-section structure and reinforced joints to tap the degree).
Vibration rod inserted into the lower layer has been the depth of concrete should be not less than 5cm, strictly control the vibrating time, usually about 20 seconds, to prevent leakage or vibration
Because it is necessary to remove the bubbles in the concrete, tamping, so that the concrete dense combination of concrete to eliminate honey and other phenomena.
The main role is to improve its strength, to ensure the quality of concrete components.
