SikaRapid®-2

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.
