The constant increase in requirements for reinforced concrete constructions of buildings and structures, ensuring their durability and operational reliability requires the use of multi-component concrete mixes with the mandatory use of additives of various nature, the functionality of which can be enhanced by modification with nanomaterials. Obviously, the production of high- tech concrete mixes with cyclic repeatability of specified characteristics largely depends on the technology adopted. The article presents the results of experimental studies on evaluating the properties of concrete mixtures and concretes, depending on the order in which the initial components are fed into the concrete mixer during mixing. Based on the data obtained, it is concluded that it is necessary to carefully develop methods for preparing concrete mixtures, including the process of loading components into a concrete mixer, which will improve the quality of construction products and reduce their cost.
