The method is a mechanised variation of the slump test and includes determination of workability of fresh concrete by performing vibration to concrete after removal of the slump cone. The assembly is mounted upon a small vibrating table operating at a fixed amplitude and frequency.
The time to complete the required vibration gives an indication of the concrete workability. The set consists of vibrating table, slump cone, graduated rod with transparent plate, filling cone and tamping rod.
