Sika® Air-260
Sika® Air-260 is an aqueous solution of a unique, synthetically manufactured surfactant for the air entrainment of concrete. Sika® Air-260 exclusive formula provides superior controllability of the air content and finishability in air-entrained concrete.
Sika® Air-260 increases concrete’s durability, making it more resistant to the damaging effects of freezing and thawing, while improving workability and reducing bleeding. Sika® Air-260 is carefully formulated and subjected to stringent quality control in order to guarantee superior results in both the plastic and hardened concrete.
- Superior resistance to freeze/thaw cycles and scaling
- Improves workability
- Reduces bleeding
- Improves appearance of architectural concrete
- Reduces size and number of capillary chanels, increasing impermeability
- Increased compressive strength in lean mixes
- Substantially increased durability
- Increases moisture retention for cement hydration
- Superior air-void system
Usage
Sika® Air-260 is designed for use in exterior concrete such as highway paving, curb and gutters, sidewalks, driveways, slabs, walls, or other areas needing protection from freeze/thaw damage or the harmful effect of de-icing salts. Sika® Air-260 is effective in increasing the workability of the concrete, especially in lean or harsh mixes.Advantages

Application
Mixing
Mixing
For best results, it is recommended to dispense Sika® Air-260 into the batched water or with the aggregates. Sika® Air-260 is compatible with other Sika® admixtures. However, each admixture should be added separately to the mixer.
Recommended Dosage
The recommended dosage range for Sika® Air-260 is 7-400 mL/100 kg (0.1 to 6.0 fl. oz. per 100 lb) of cementitious material. The nature of various concrete materials, slump, ambient air temperature, mineral additions, mixing time and energy will affect dosage rates. It is suggested that trial batches be conducted in order to determine the required dosage to obtain the required percentage of entrained air. In addition, a regular program of air tests should be instituted in order to adjust the dosage to changing conditions.
