EStudy on Compaction of Concrete by Horizontal Vibration with Low Frequency and Large Amplitude

The noise of the vibrating table at a concrete plant disturbs the workers at the plant and the people who live around it. This paper proposes a new compaction method that is named as the horizontal vibration method. The new method has the ability to replace the vibrating table method. In this method, the mold is shaken in the horizontal direction with the low frequency and large amplitude.

This paper presents the relationship between the amplitudes, frequencies, compaction time of the horizontal vibration and the resulting compaction, then describes the effect of horizontal vibration on the concrete. The results of this study indicate that the good compaction can be attained with the horizontal vibration method.

(a) Horizontal vibration method (slump:21cm+ -1.5cm)

(b) Table vibration method (slump:12cm+ -2.5cm)
