Sika® Rapid 1

SikaRapid®-1 is a liquid hardening accelerator for concrete and mortar.

SikaRapid®-1 promotes early strength development without negatively influencing final strengths.

USES

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 mainly used for the following applications:

  • Precast concrete
  • Prestressed 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

CHARACTERISTICS & ADVANTAGES

SikaRapid®-1 provides the following advantages through accelerated hardening of
the concrete:

  • When applied with a HRWR/Superplasticiser, SikaRapid®-1 will not change the fresh concrete properties
  • Faster turnaround of formwork in precast applications
  • Early release of stressing cables in prestressed concrete structures
  • 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

SikaRapid®-1 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.
