Cemairin 260

Air-entraining admixture

Cemairin 260 is an air-entraining admixture for concrete, formulated from selective polymers to create highly stable microscopic air bubbles which distribute uniformly in the concrete mix.

This effect can be used to improve the resistance of concrete mixes against freezing and thawing, severe weathering and de-icing compounds.

  • Improves the durability of concrete against frost and severe weathering conditions.
  • Significantly improves the cohesion of concrete mixes.
  • Improves workability.
  • Chloride-free.

Cemairin 260 is suitable for use in the following applications:

  • In areas where there is a potential for frost damage such as roadways, airport aprons and runways.
  • Can be used with conventional ready mix concrete as well as concrete mixes which include micro-silica, fly ash as well as GGBS.

Cemairin 260 is available in 275 gal (1,041 litre) IBC totes. Bulk supply in tanker trucks is also available upon request.


Cemairin 260 has a minimum shelf life of 12 months from date of manufacture if stored at temperatures between 35°F and 122°F (2°C and 50°C).


The recommended dosage of Cemairin 260 to achieve air content in range of 3 - 7% is ½ to 4.5 fl oz/100 Ib (32 - 292 ml/100 kg) of cement or cementitious materials in the mix including GGBFS, PFA or micro-silica.

Representative trials should first be conducted to determine the optimum dosage of Cemairin 260 to meet the performance requirements by using the materials and conditions in actual use.


Cemairin 260 complies with ASTM C260 standard.
