SikaRapid®-505 are admixtures that accelerates the early setting times of concrete. Setting times for non-accelerated concrete become longer as temperatures get colder. This affects finishing times of floors. The set accelerating admixtures counter this set retardation and can shorten setting times back to normal values (depending on dosage).
- SikaRapid®-505 can be used with all types of Portland cement, including sulphate resistant cement.
- Provides faster setting in colder conditions.
- SikaRapid®-505 can be used in reinforced concrete.
- SikaRapid®-505 assist in reducing the water : cement ratio in concrete while still maintaining workability.
- Air Entrainment less than 1 %
- SikaRapid®-505 contains chlorides
