“…These indices cannot provide a reliable assessment of the efficiency of concrete mixtures compacting as they do not take into account a number of important parameters: the direction and type of the vibratory action, the geometric dimensions of the formed product and physical and mechanical characteristics of the concrete mixture. A specified theory, presented in papers [7], [8], [9], [10], [11], [12], [13], 14] in detail, describes the mechanism of propagation of resilient-plastic waves of deformation and breakage of structural links in a concrete medium, its plastic flow and displacement of air out of the mixture structure and formation of a dense structure under the impact of vibration. The authors substantiate the efficiency of formation of concrete products from harsh and plastic concrete mixtures based on the stresses occurring in the concrete medium, which break the structural links with a certain frequency of vibratory action.…”

Purpose. The creation of the compacting vibratory process theoretical basis enabling the assessment of the efficiency and the choice of rational modes of the vibration influence on the concrete mixture, based on the minimal energy input in the process of its compacting. Methodology. The paper contains the description of the mechanism of compacting under the action of external vibration forces whereat a variable tensely deformed condition occurs in the concrete mixture. In this case the primary structural links break, the links between its separate elements weaken, the final movements of mineral particles result in the creation of a more compact packing. As the basic factor determining the character of the compacting process, the authors propose to use the product of voltage and the velocity of the vibratory action, which presents the power of the vibratory action on the compacted medium. Results. The authors have obtained analytical expressions enabling the determination of the growth of the concrete mixture density in time function depending on the type of the vibratory load and the power of the applied vibratory action on the compacted medium. The paper contains the theoretical and experimental values of the specific work that provides compacting up to the values required by the technological norms depending on the consistence of the concrete mixture at vertical and horizontally directed vibrations. Conclusions. The authors have specified the existing hypothesis and proposed a more general power hypothesis of the process of vibratory compacting of concrete mixtures, applicable to the description of the vibration process and concrete media treatment by various vibratory mechanisms, tools and machines. One can use the obtained results to set the rational modes and duration of the vibratory action on the compacted medium depending on the amount and type of the specific work of compacting and also to determine the basic parameters of vibration machines of various technological purpose.

“…Thus, pulsation of the delivery pressure in the mortar pumps is caused both by the structural features of their drives [6] and internal (rheological [7,8]) properties of the building mortars. Moreover, at the stage of designing new mortar pumps, it is necessary to develop such a design of the drive and entire mortar pump which would provide minimal pulsations of the delivery pressure [9].…”

“…At the same time, the frictional forces arising inside the concrete mixture between its individual constituents during the reorientation of mineral particles and their convergence, deformation, redistribution of the binder were not taken into account. Therefore, in order to justify the rational parameters of the vibrating machine and determine the necessary mode of vibration action, it is necessary to accurately determine the change in the physico-mechanical characteristics of the compacting medium, take into account the effect of the emerging forces of resistance of the concrete mixture under influence vibrations of the vibrating machine [16], [17]. The aim of this work is to study the process of vibrating machine with a compacting medium interaction and to determine the regularities of its oscillations during different consistency concrete mixtures compacting…”

Dynamic system calculation scheme "Vibrating machine is compacting medium", where the latter is represented as a system with distributed parameters is compiled. As a result of the wave equation of oscillations solution, the law of compacting medium deformation over the entire thickness of the concrete layer is determined depending on the increasing density of the molded mixture, its physico-mechanical characteristics, the thickness of the concrete layer, the mass of the oscillating part of the vibrating machine, the frequency and amplitude of the disturbing force, elastic suspension stiffness and coefficient inelastic resistance. Changes in the compacting concrete medium resistance forces during the vibration compaction, depending on its consistency are determined.
