Description:

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 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

Characteristivcs/Advantages :

SikaRapid®-1 provides the following advantages through accelerated hardening of the concrete:
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. It is therefore suitable for use in reinforced concrete
