Air Pressure Meter | Deslauriers, Inc

The Pressure Meter is used for measuring the amount of entrained air in freshly mixed concrete. The test method equalizes a known volume of air in the pressure chamber, with the unknown value of entrained air in the meter’s concrete filled base. The amount of entrained air is then read on the meter’s gauge as the direct percentage of air entrained in the sample.

Adjusting Air Entrainment| Concrete Construction Magazine

Feb 17, 2009 · Ideally they are spaced no more than about 0.008 inches apart or less. When air entrainment is added to concrete, there is some effect on slump, and compressive strength is reduced by about 500 psi in a standard 6-bag (564-pound) mix. There are two kinds of air in concrete: entrapped and entrained. Entrapped air is a result of the mixing process.
