Type: article
Abstract: The article discusses the problems associated with the mixing efficiency of concrete mixtures in gravity con-crete mixers, which are widely used in construction sites due to their simplicity of design and mobility. Mod-ern requirements for energy efficiency and quality control accuracy require the development of advanced methods that can ensure high homogeneity of concrete mixtures with minimal energy consumption. Consid-erable attention is paid to the influence of the geometry of the drum and the working bodies of the concrete mixer on the mixing process. Various approaches to mathematical modeling have been described, which take into account the physical and mechanical properties of the concrete mixture and the nature of its movement during rotation. The analysis of the rheological properties of concrete mixtures shows their signifi-cant impact on the mixing efficiency. Studies demonstrate that the proper selection of the drum rotation speed, the angle of inclination of the blades and the duration of mixing allows for an optimal balance between the various physical forces acting on the particles. Prospects for further research are highlighted, including the development of complex models that would take into account various factors and would allow predicting the behavior of the mixture in real conditions.
