Air Entraining Agents-Plastit® AEA

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

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.

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

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
