What is the problem of over vibration of fresh concrete?
For proper compaction of concrete by immersion vibrators, the vibrating part of the vibrators should be completely inserted into the concrete. The action of compaction is enhanced by providing a sufficient head of concrete above the vibrating part of the vibrators. This serves to push down and subject the fresh concrete to confinement within the...

Consolidation of concrete—required or not?
Section 5.3.2.5 of ACI 301 states that unless otherwise specified, consolidate concrete by vibration. This applies to concrete slabs as well. In the Optional Requirements Checklist in ACI 301, Section 5.3.2.5 permits other methods of consolidation, too: “Specify if consolidating of concrete by methods other than vibration will be permitted.”.
