Air Meter Calibration: A Step-By-Step Guide - Gilson Co.

Air entrained concrete mixes have greatly enhanced freeze/thaw durability and service life over plain concrete. Still, too much air content causes a significant reduction in strength, and too little is ineffective. Since the percentage of air specified is critical to how the mix performs, accurate tests for concrete air content are essential.

It measures the air content in fresh mix concrete. The test procedure equalizes a known volume of air in the pressure chamber, with the unknown value of entrained air in the concrete-filled base. The amount of air entrained is then read on the meter's gauge as the direct percentage (to the nearest 0.1%) of air entrained in the concrete.

Identifying a Problem Through ... - Concrete Construction

Air entrainment: The total air will be checked throughout and examined at the surface to see if surface air was removed during finishing. As a contractor, the best procedure to follow during construction is to have your own air meter, preferably a pressure meter for normal concrete, and to make your own air tests at least twice during a day's pour.

How to Use Air-Entrained Concrete ... and Why You Should Use ...

The strength of air-entrained concrete depends on the water/cement ratio as it does in non-air-entrained concrete. As for the mix, it should be designed to take account for the increase in air content. The water content for an air-entrained mix will be 3 to 5 gallons per cubic yard less than for a non-air-entrained mix having the same slump.

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.
