Set accelerating admixture

SikaRapid®-2 is a low alkali liquid set accelerator for concrete and mortar. SikaRapid®-2 promotes early strength development without negatively influencing final strengths.

    SikaRapid®-2 provides the following advantages through accelerated set and hardening of the concrete:
    When applied with a HRWR/Superplasticiser, SikaRapid®-2 will not change the fresh concrete properties
    Faster turnaround of formwork in precast applications
    Reduced or eliminated heat or steam curing
    Continuous concreting at low temperatures
    No negative effects on the final strengths
    SikaRapid®-2 does not contain chlorides or any other ingredients which promote the corrosion of steel. It is therefore suitable for use in reinforced and prestressed concrete structures.
