What action is taken with the pressure method bowl after each lift of concrete is consolidated?

After each lift of concrete is consolidated, the correct action taken with the pressure method bowl involves tapping it 10-15 times with a mallet. This tapping is essential because it helps to remove any trapped air bubbles and ensures the concrete is properly settled and compacted within the bowl. Proper consolidation is critical for achieving accurate measurements of the density and the performance characteristics of the concrete being tested.

Tapping helps create a uniform surface and can positively influence the results by making sure the concrete fills the bowl evenly without voids, which could misrepresent the concrete's actual properties. This step is part of the standard procedure in ensuring that the consolidation is effective, aiding in the accuracy of subsequent measurements or assessments required in concrete inspections.
