| Summary: | The article addresses the problem of the quality improvement in respect of the concrete mix preparation in the context of intensive mechanization and automation. The co-authors suggest new processes to improve the performance reliability of the operating element of a mixer through the improvement of the wear resistance of its blades. The build-up of the wear-proof layer has boosted the durability of the components of the operating element of a mixer. The logical relationship between the mechanized and automated operations enabled the co-authors to adjust the optimal composition of the concrete mix. The use of composition adjusting devices, operating in the automatic mode, has substantially optimized the process of batching the mix components and the water content in the concrete mix. The co-authors provide a diagram describing the dependence between the mean square value of the outgoing signal of vibration acceleration and the mixing time until the mix is ready. The co-authors have identified that the higher the moisture content, the smaller the mixing time, and, hence, the higher the capacity of a mixer. A hybrid approach to the mix quality improvement has also reduced the operating expenses.
