SikaRapid®-1 MY

Hardening accelerator

SikaRapid®-1 MY is a new generation hardening accelerator for concrete and mortar. It increases the early strengths of concrete without negatively influencing final strengths.

SikaRapid®-1 MY is normally used in combination with a superplasticiser. The addition of SikaRapid®-1 MY does not change the positive properties (for example fluidifying, slump retaining, etc.) of the superplasticiser. Depending on the dosage of SikaRapid®-1 MY an increase in early strengths during the first 24 hours of up to 100 % in comparison with normal Sikament® concrete can be achieved. Depending on the brand of cement-type used and the temperature of the fresh concrete, the effect may vary slightly. It is recommended to combine SikaRapid®-1 MY only with normal setting types of Sikament®.

Usage

  • SikaRapid®-1 MY can be used where extremely high requirements for early strengths within 6–24 hours have to be achieved
  • SikaRapid®-1 MY does not contain any chlorides and can therefore be used without any reservations for reinforced as well as prestressed concrete. However, it should not be used in combination with expanding or shrinkage compensating admixtures

Application

Application Information

DISPENSING

SikaRapid®-1 MY is either mixed with the gauging water or added simultaneously with the gauging water into the concrete mixer.

It is also possible to add SikaRapid®-1 MY to the basic concrete carried in a transit mixer at the place of discharge. In this case, an additional mixing time of 1 minute per m³ of concrete must be observed. Prior to its discharge the concrete should be checked visually for uniform consistency.
Consumption

Recommended Dosage

SikaRapid®-1 MY shall be dosed at between 0.5–1.5 % by weight of cement depending on desired acceleration effect.
