Vee Bee Consistometer

Vee bee consistometer test is named after the Sweden developer V Bahrmer and it is covered by IS: 1199–1959. It is used to determine workability of concrete using consistometer. It is usually performed on dry and fresh concrete and it is not suitable for very wet concrete.

Vee bee consistometer test carries out the relative effort measurement to change the mass of the concrete mix from one definite shape to another definite shape (from the slump conical shape to the cylindrical shape) by conducting vibration process. This effort is known as remoulding effort and the measurement of the effort is done by time measurement in seconds. It is called as Vee Bee Seconds.

When the concrete mix having slump value more than 50 mm remoulds quicker where measuring the time is not possible, the time
