The goal of this work is to describe mixing process of mortars in concrete mixer drums in terms of energy balance of "drum mixer-concrete mixture" system as discrete and continuum models. The analysis of existing studies and publications of the movement of building mixtures particles for internal mixing tools, such as blades and the inner surface of the drum has been made. The main problem is highlighted, namely, that of the methodology of analysis and evaluation of the efficiency of the mixing apparatus of the blades, analysis of the movement of particles in the mixture. Methodology. Researches in this work are of analytical character. Results. Using the results of these studies allows to improve mixing process by taking into account the workflow criteria proposed. Mixing processes similarity criteria based on assumptions simultaneous processes of dispersion, mass transfer, physical and chemical transformations are studied. Analytical studies highlight that as a...
