What are common signs of inadequate consolidation, and how should the inspector respond?

Inadequate consolidation shows up as voids and honeycombing in the concrete, which are direct signs that the mixture hasn’t been compacted enough to fill around the aggregate and remove air pockets. The proper response is to take corrective action on the spot: re-vibrate the area with the right energy, rework or rake the surface to help the paste fill the spaces, and if the voids are too large or widespread, remove and replace the affected portion to meet the required density and strength. Cracks can arise from other causes like shrinkage or movement, a slightly rough surface can result from finishing techniques, and over-tamping is not a recommended remedy because it can cause segregation or surface damage.
