The article presents the results of experimental studies on the compaction process of polystyrene concrete mixture using a specially developed combined impulse-vibration installation. The relevance of the research is due to the need to increase the density and compressive strength of lightweight concrete products by improving the compaction technology. The aim of the study is to determine the effective compaction parameters (gap between frames, mass of the loading device, and duration of action) and to evaluate the influence of horizontal vibrations on the strength of the products. The research methods included experimental design, physical modeling, and analysis of results using response surface methodology. It was found that the use of combined loading allows for an increase in compressive strength by 5–7% compared to traditional impulse compaction. The obtained results can be used to optimize technological parameters for the production of wall elements made of polystyrene concrete.
