Sika® Air-260
AIR-ENTRAINING ADMIXTURE FOR CONCRETE
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
