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.

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.
