The method of mechanical activation of hydrated lime in a vibrating activator of bunker type was offered in this work. The influence of design features and angle of fixing of vibrating blades on the speed and degree of dispersion of hydrated lime was investigated by measuring the change in the logarithmic decrement of mass attenuation during vibro-activation. The effect of the duration of the vibro-activation process on the dispersion in the system «hydrated lime--water» was studied. The efficiency of lime dispersion was shown in the case of mounting the blades at the angle of 860 for 40-60 minutes. Comparative studies of the strength of cement stone showed that the addition of vibro-activated hydrated lime in an amount of 2 wt.% leads to an increase in the strength of lime-cement compositions.
