Presented and theoretically justified ways of improving the technology of centrifugation, to increase the uniformity of the concrete structure in the cross section, for example, by way of separate introduction of the components of concrete, the essence of which in the manufacture of spun goods consists in the introduction into the molding unit prior to the stage of compaction of coarse aggregate. The results of physical and mechanical tests of centrifuged concrete, showing that the layer-by-layer introduction of the concrete mixture components by the first method leads to an increase in the compressive strength in all layers of centrifuged concrete

Keywords: concrete, centrifugation, uniformity of structure, layer-by-layer introduction of components, compaction, water absorption at capillary suction, strength
