Sika® Air-260

AIR ENTRAINING ADMIXTURE

Sika® Air-260 is an aqueous solution of a unique, synthetically manufactured surfactant for the air entrainment of concrete. 

Sika® Air-260 provides an enhanced concrete durability with a greater resistance to freeze-thaw cycles.      Sika® Air-260 also provides:   
  • Controllability of the air content,
  • Improved air-void system,
  • Reduced size and number of capillary channels,
  • Improved workability especially in lean or harsh mixes,
  • Reduced bleeding.
   Sika® Air-260 does not contain intentionally added chlorides.

Application

Application Information

Mixing

Measure the required quantity manually or by automated dispenser. Add Sika® Air-260 directly to the mixing water or to the sand stream, do NOT mix with dry cement. Sika® Air-260 may be dispensed on-site directly prior to placement. Care must be taken to mix thoroughly. When used in combination with other admixtures dispense each admixture separately into the mix.

  

Compatibility: Sika® Air-260 can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials.
Consumption

Recommended Dosage

The typical dosage rate of Sika® Air-260 will vary between 7-400 mL / 100 kg of cement or cementitious materials. Various factors will affect the dosage rates. Dosage rates outside of the typical range may be used. 

  

It is recommended to conduct trial mixes with the actual materials to determine the required dosage for optimum performance.

  

To the extent specialized materials (such as microsilica) are specified, extreme ambient project conditions are encountered, or other unusual project conditions require special consideration outside the recommended dosage, please contact your local regional Sika Representative prior to using the Sika admixture.
