Vibroacoustic monitoring of the homogeneity and workability of concrete mixes by their hydromechanical state in the process of mixing

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.
