VEE-BEE test

AIM

To determine the workability of fresh concrete by using a

Vee-Bee consistometer as per IS: 1199 - 1959.

APPARATUS

VEE-BEE CONSISTOMETER

PROCEDURE

i) A conventional slump test is performed, placing the slump

cone inside the cylindrical part of the consistometer.

ii) The glass disc attached to the swivel arm is turned and

placed on the top of the concrete in the pot.

iii) The electrical vibrator is switched on and a stop-watch is

started, simultaneously.

iv) Vibration is continued till the conical shape of the concrete

disappears and the concrete assumes a cylindrical shape.

v) When the concrete fully assumes a cylindrical shape, the

stop-watch is switched off immediately. The time is noted.

REPORTING OF RESULTS

The consistency of the concrete should be expressed in

VB-degrees, which is equal to the time in seconds, recorded in

Para v), above.
