This method is a mechanical variation of the simple slump test which includes determination of the workability of concrete. The concrete is formed in a slump cone positioned in a container and it is vibrated after removing the cone on a small vibrating table operating at a fixed amplitude and frequency. A plastic spacer disc, in which, contact with the upper surface of the wet concrete guides the operator to judge when the compaction is complete. The time to complete the required vibrations gives an indication of the workability of concrete, which is expressed in Vee-Bee degrees.
