The method of monitoring of the homogeneity and determination 
of the workability index of a concrete mix from the level of vibroacoustic 
vibrations excited in the mixer in mixing of concrete has been described. 
The vibration-level values dependent on the hydromechanical state of 
a concrete mix and its rheological characteristics in the process of mixing 
and formation of its vibroacoustic image have been measured at the check 
point of the lining of the concrete mixer and have mathematically 
been processed.

Keywords: concrete mix, viscoplasticity, homogeneity, vibration.
