Sika® AIR

AEA – Air Entraining Agent

Sika® AIR is an air-entraining agent based on synthetic surfactants. Its efficiency is based upon the entrainment into the mix of a high number of correctly sized and evenly distributed air bubbles.

  • Increased freeze-thaw resistance.
  • Reduced bleed water.
  • Improves concrete workability.
  • Increases cohesion and reduces the risk of segregation.
  • No effects on setting time.

Usage

Sika® Air is used to:
  • improve resistance to freeze-thaw action in hardened concrete;
  • increase cohesion, reducing the concrete’s tendency to bleed in the plastic state;
  • improve compaction of low workability mixes including semi-dry concrete.
 

Advantages

  • Increased freeze-thaw resistance.
  • Reduced bleed water.
  • Improves concrete workability.
  • Increases cohesion and reduces the risk of segregation.
  • No effects on setting time.

Consumption

Recommended dosage

Typical dose rate for general concrete production ranges within 50-150 ml  per cubic meter of concrete. For low slump concrete (<65 mm slump) and pavement type concrete, specific concrete that contain high volumes of fly ash, substantially higher dose rates of Sika Air may be required to achieve the desired air content. Typical dose rates for high volume fly ash or low slump concrete range from 100-600 ml per cubic metre of concrete.

Optimum dosage depends on the type of concrete, site conditions, mix proportions and desired plastic and hardened concrete properties. Laboratory and/or field trials are essential in determining the optimum dosage. Factors affecting air content include sand, cement, fly ash, aggregates and combinations with other admixtures.
