This method is a mechanical variation of the simple slump test that includes determination of the workability of concrete.

The concrete is formed in a slump cone positioned in a container. It is vibrated at a fixed amplitude and frequency after the cone is removed, on a small vibrating table.

A plastic spacer disc on the top surface of the wet concrete allows the operator to judge when the compaction is complete.

The time to complete the required vibrations gives an indication of the workability of the concrete, which is expressed in Vee-Bee degrees
