Reviewed the processes of preparing concrete mixes and transporting construction mortars in mechanised construction production systems, taking into account the effects of vibration on the working vessels of the process equipment.

Modern construction production technologies are characterized by a high level of mechanization and integration of technological operations, within which concrete mixing, pumping, and plastering equipment operate as an interconnected technological system. Efficiency of such systems largely depends on coordinated operating modes of their components, rheological properties characterizing concrete and mortar mixtures, as well as dynamic characteristics inherent to drives and control systems. At the same time, during plastering unit operation, adhesion of construction mixtures to internal bunker surfaces occurs, which leads to disruption of uniform material supply and reduction in equipment productivity. An effective way to eliminate this phenomenon involves applying vibration to bunker walls, which ensures stabilization of mixture transport. Therefore, consideration of vibration processes in mathematical models describing mechanized systems for preparation and supply of construction mixtures represents a relevant scientific and practical task.
