Use

Sika AER meets the requirements of ASTM C260 for Air Entraining Admixtures.

Characteristics and Advantages

Durability: Air entrainment is recognized as the most effective prevention against concrete scaling in exposed environments. Air entrained concrete delivers particular benefits in the form of increased concrete durability. This is important in colder climates where frost and freeze-thaw cycles can cause scaling and damage to the concrete surface. Air entraining agents help to prevent scaling by creating millions of microscopic air voids that water trapped in the concrete can expand into when the concrete freezes, thus preventing cracks caused by the natural expansion. Entrained air voids in the concrete will also increase durability in harsh environments where concrete is exposed to deicing salts, marine salts and sulfates.
Workability and Placeability: Workability and placeability are also improved by the lubricating action of the microscopic bubbles in the concrete. The concrete flows better, bleeding and shrinkage is reduced because lower water content is needed for desired workability

Use

Sika Multi-Air is recommended for all normal, low and very high slump concrete exposed to freeze-thaw conditions in the presence of de-icing salts and/or sea water.

Characteristics and Advantages

Sika Multi-Air primary advantage is to entrain an effective air void matrix with excellent stability. Sika Multi-Air Liquid’s exhibits the following characteristics:

• Reduces potential deterioration due to freeze-thaw cycles
• In a saturated condition
• In the presence of de-icing salts
• Reduces bleeding and segregation
• Improves cohesiveness, workability and finishing characteristics

Use

Air entrainment is recognized as the most effective means to prevent concrete damage, including scaling, caused by repetitive freeze-thaw action. Air entraining agents help to prevent scaling by creating microscopic air voids in the concrete that entrapped water can expand into when it freezes. This prevents expansive cracking and scaling. Air voids entrained in the concrete will also increase durability in harsh environments where concrete is exposed to deicing salts, marine salts and sulfates. Additionally, air entraining admixtures also improve workability and placing of a concrete mix while reducing bleeding.
