Concrete Air Entraining Agent Used For Ready Mix Concrete

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 ...

Entrained Air: Now You See It, Now You Don't | American ...

Jul 26, 2018 · Air entrainment is usually obtained by incorporating a chemical admixture while mixing concrete on the job site. The chemical agents used are categorized as surfactants or soaps. These chemicals help stabilize bubbles within the concrete mix. The network of bubbles reduces internal stresses within the concrete by providing spaces for water to ...

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.
