Acceleration distribution on vibration forms

For large-area compaction forms, in particular, a uniform introduction of the compaction energy on the interface between form wall and concrete mix, plays a large role. The vibration oscillation has here proved to be a good assessment criteria. To assess the uniformity of acceleration distribution, an approach that has been harmonized with the compaction technology used must be taken. In what follows, a uniformity index is proposed. It is a single numerical value based on mathematical principles, easy to use in practice.
