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.
- 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.
Usage
Sika® Air-260 is designed for use in concrete requiring air entrainment and protection from freeze-thaw damage or the harmful effect of de-icing salts. Sika® Air-260 is specifically designed for use in high slump or SCC, but is suitable for use in a variety of concrete mixes.Advantages
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.
Packaging

Application
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.
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.
