Removal of the air bubbles is complete after you have worked the tool
throughout each effective range, the concrete stops shrinking, and the mortar
has risen evenly to the surface, giving off a light appearance. Gently remove
the operating tool not to leave holes.
NOTE:

Vibrating too long in a single place causes concrete segregation.
•
When the coarse aggregates segregates when placing concrete, shovel
out the coarse aggregate and put it where there is plenty of mortar. Then
