3.Area cone beside concrete and put tamping rod
across the top of the cone
6.Measure down from the bottom of tamping rod of

1. 1. Same as slump testSame as slump test
2. 2. After the Slump test we can start ve-be testAfter the Slump test we can start ve-be test
3. Switch on the electrical vibrations and start the
stopwatch. Allow the concrete to remold by
spreading out in the cylindrical container. The
vibrations are continued until the concrete is
completely remolded, i.e., the surfaces becomes
horizontal and the whole concrete surface adheres
uniformly to the transparent disc.
4. Record the time required for complete
remolding seconds which measures the workability
expressed as number of Vee-Bee seconds.

19. ADvAntAgEs:
1. The Vebe consistometer is a dynamic test and can The Vebe consistometer is a dynamic test and can
be used on concretes that are too dry for the slump be used on concretes that are too dry for the slump
test. test. 
2. Test results are obtained
directly. 
DisADvAntAgEs:
1. Due to the need to ensure that all vibration is
kept within the test device, the size of the test device
makes the Vebe consistometer generally unsuitable
for field use. 
2. The test device only works for low slump
concretes.
