Název v původním jazyce

Analysis of the migration process of concrete layers during compaction

Popis výsledku v původním jazyce

The article describes the behavior of a fresh concrete exposed to the effects of vibration. The individually deposited layers of concrete mix are able to migrate in the vertical and horizontal direction in the specimen or structure. This phenomenon is simulated using successively deposited layers of colored concrete of defined height. The specimens were exposed to vibrations of variable frequency and amplitude. The degree of interconnection between the layers is determined by using regular sections across the specimens to observe the differences in the movement and interconnection of the layers for different consistencies of the concrete mix. The results summarized in this paper present new results of continuous research aimed at a more detailed description of the vibration behaviour of fresh concrete, as this phenomenon is relatively marginally addressed in the current standards.
