- SikaRapid®-22 AU does not contain chlorides or any other materials which promote the corrosion of steel reinforcement.Therefore It is suitable for reinforced and pre-stressed concrete
- Faster setting time even at low temperatures
- High early strength
- Increase the turnover of the formwork
- No negative impact on the effectiveness of superplasticizers and other admixtures
SikaRapid®-22 AU is a non chloride set and hardening accelerator for concrete, mortar and grout.
SikaRapid®-22 AU is recommended for use in premix and precast concrete where fast setting and hardening time is required.
As a result, SikaRapid®-22 AU allows:
▪ Faster finishing of concrete surfaces
▪ Improved early strength of premixed concrete
▪ Faster slip-form production
▪ Used in ready mix concrete in cold climates
