Concrete Vibrating Table

Concrete Vibrating Table

1.     Purpose

 Vibrating table is used for proper compaction of concrete while casting specimens for compressive strength determination.

 2.     Procedure

 i.     After preparing the concrete mix, put moulds on the vibration table platform.

ii.   Fill concrete in the mould in layers of 50 mm deep.

iii.  In placing each scoopful of concrete, move the scoop around the top edge of the mould as the concrete slides from it, in order to ensure a symmetrical distribution of the concrete within the mould.

iv.  Let each layer compact by vibration.

v.    After compacting concrete in 3 layers, finish the surface of the concrete level with the top of the mould.

vi.  Stop the table and remove the mould from it.
