The research relevance is determined by the need to improve construction production technological set operational efficiency ensuring concrete mix preparation and plastering mortar delivery under variable operating conditions. The study objective is to establish relationships between mixing equipment kinematic parameters, construction medium rheological characteristics, and conveying system geometric parameters and the technological set generalized efficiency indicator. The study uses mathematical modelling methods of construction mix mixing and transportation processes considering their structural-mechanical properties and equipment energy characteristics. An extremal dependence of the generalized efficiency indicator on mixer working body rotational speed was established, and the influence of mixture rheological parameters and pipeline system geometric characteristics on pressure loss and material delivery stability was determined. The obtained results enable substantiation of rational construction mix preparation and transportation technological set operating modes considering process energy and technological indicators.
