SikaRapid®-1 - Concrete Admixture
Verified by manufacturer 3 months ago
Hardening accelerating concrete admixture.
Application
SikaRapid®-1 is especially suitable for any application where fast early strength development plays a major role, or is of crucial importance within 6 to 24 hours. SikaRapid®-1 is used for the following applications:
- Precast concrete.
- Ready- mixed concrete where early demoulding is essential.
- Cold ambient temperatures to achieve sufficient strength gain.
- Slip-formed concrete.
- Ready- mixed concrete where minimum time delays are critical.
Description
SikaRapid®-1 is a liquid hardening accelerator for concrete and mortar. SikaRapid®-1 promotes early strength development without negatively influencing final strengths.
Features and benefits:
- Faster turnaround of formwork in precast applications.
- Reduced or eliminated heat or steam curing.
- Fast construction processes and early load bearing capacity.
- Continuous concreting at low temperatures.
- No negative effects on the final strengths
- When applied with a superplasticizer, SikaRapid®-1 will not change the fresh concrete properties produced by the superplasticizer.
- SikaRapid®-1 does not contain chlorides or any other ingredients which promote the corrosion of steel.
- Suitable for use in reinforced concrete.
