Air Entraining Agents-Capcoair SLA

Plastit AEA is a chloride-free admixture based on synthetic surfactants and is supplied as a dark brown solution. Plastit AEA acts on the interface of the cement/aggregate particles and mixing water to produce microscopic air bubbles evenly distributed throughout the concrete

Properties And Effects
  • Provides concrete with resistance to freezing and thawing Improves cohesion, reduces segregation and bleeding Gives dense, uniform, close textured surface to concrete Excellent air bubble stability Consistent performance, even with changes in aggregate quality and ambient temperature Effective in low workability concrete Suitable for use in Middle East conditions.
Applications
  • To produce air entrained concrete for increased durability, resistant to damage by frost and de-icing salts, and to improve the cohesion and workability of concrete mixes where poorly graded aggregates must be used, and in any situation where bleeding, segregation or sand runs occur Typical applications include Concrete roadways Bridge decks Airport runways and taxiways Other extensive areas of concrete exposed to potential frost damage
Scope and Method of Use

The optimum dosage Plastit AEA to meet specific requirements should always be determined by trials using the materials and conditions that will be experienced in use. The normal dosage range is between 0.2 to 0.6 kg/100 kg of cementitious materials

Physical and Chemical Properties
  • Appearance Brown Liquid
  • Specific gravity 1.02 gr/cm3 at 20°C
  • Chloride Nil to BS5075
  • Air entrainment Typically between 2% and 6% additional air is entrained at normal dosages
  • Alkali content Typically less than 5.0 g. Na2o equivalent/liter of admixture. A fact sheet on this subject is available
Maintenance And Safety
  • Packaging Plastit AEA is available in 20 kg containers and 200 kg drums Storage Plastit AEA has a minimum shelf life of 12 months provided the temperature is kept within the range of 5°C to 35°C. Should the temperature of the product fall outside this range then contact CAPCO for advice. Freezing point: Approximately -2°C
