ASTM C231: Testing Air Content of Concrete With a Type B ...

This tests purpose is to get the air content of a sample of concrete using a pressure meter. In the meter you have a known volume of air at a known pressure in a sealed air pot with an unknown volume of air being contained inside the sample of wet concrete. You set it to the percentage of air (your initial pressure) where the pressure is equalized inside the chamber, fill it with concrete and water so that the only air left is the air inside the concrete, and then release the pressure inside of

Air-Entrained Concrete - Portland Cement Association

These air pockets relieve internal pressure on the concrete by providing tiny chambers for water to expand into when it freezes. Air-entrained concrete is produced using air-entraining portland cement, or by the introduction of air-entraining agents, under careful engineering supervision, as the concrete is mixed on the job.

Effect of Air Entrained Concrete on Strength of Concrete

Typically, it may be assumed that a loss of 5% in compressive strength of concrete occurs due to each 1% by volume of entrained air in the concrete mix. In order to estimate water-cement ratio required for an air entrained concrete, an allowance for strength reduction is incorporated in the mix design and higher target mean strength is assumed.
