VEBÉ TEST

STANDARD: ASTMC143, BS1881

This  test  method  is  a  variation  of  the  simple  slump  test and  subjects  the  concrete  to  vibration  after  removal  from the  slump  cone.  The  time  taken  for  the  concrete  to  be recompacted  is  taken  as  a  measure  of  workability.

The small  vibrating  table  operates  at  a  fixed  amplitude  and frequency,  and  in  the  test  a  plastic  disc  is  placed  into contact with the upper surface of the concrete.

The  test  is  completed  when  the  lower  surface  of  the  disc has been completely coated with cement grout.
