Air Entraining Admixtures - North America

Air-entraining admixtures facilitate the development of a stable air-void system within concrete that increases the durability of the concrete. These admixtures impart air entrainment that results in: Increased resistance to deterioration from cyclic freezing and thawing Improved workability and cohesiveness of concrete placement; Reduced ...

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 ...

Effect of Air Entrained Concrete on Strength of Concrete

It is claimed that, the place-ability of an air entrained concrete having 7.5 cm slump is better than a non-air entrained concrete with a slump of 12.5 cm. By and large, the compressive strength of concrete is reduced by use of air entrained admixture, as shown in Fig. 1.
