SikaRapid®-2

Set Accelerating Admixture for Concrete

SikaRapid®-2 is a low alkali, chloride free liquid set accelerator for concrete and mortar which promotes early strength development without negatively influencing 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.   SikaRapid®-2 provides the following advantages through accelerated set and hardening of the concrete:
    • When applied with a HRWR/Superplasticiser, SikaRapid®-2 will have minimal effect on 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
