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.
