SikaSet® GB
SET ACCELERATING ADMIXTURE FOR CONCRETE
SikaSet® GB is an admixture that accelerates the early setting time of concrete. Setting times for non‐accelerated concrete become longer as temperatures get colder. This affects finishing times of floors. A set accelerating admixture counters this set retardation and can shorten setting times back to normal values (depending on dosage). SikaSet® GB contains chlorides and there are some limitations on its use. (Refer to Important Considerations section).
- Can be used with all types of Portland cement, including sulphate resistant cement
- Provides faster setting in colder conditions
- Can be used in reinforced concrete, however when using SikaSet® GB it is important to check that the requirements of NZS 3109 and NZS 3101 in regards to the limits on total chloride ion content are complied with. Refer to Important Considerations section.
Usage
- In colder temperatures and climates if earlier setting times are required to enable final finishing to take place
- In tidal situations where fresh concrete may be subjected to damaging wave action
- For concrete where any time delays are critical, e.g. plant shut downs, pedestrian / traffic requirements, etc.
Advantages
- Can be used with all types of Portland cement, including sulphate resistant cement
- Provides faster setting in colder conditions
- Can be used in reinforced concrete, however when using SikaSet® GB it is important to check that the requirements of NZS 3109 and NZS 3101 in regards to the limits on total chloride ion content are complied with. Refer to Important Considerations section.

Application
DISPENSING
- SikaSet® GB should be added directly with the mixing water at the ready mixed concrete plant
- SikaSet® GB may be added to ready mixed concrete on arrival at the site, however a reduction in added water must be made during batching to compensate for the additional water in the admixture dosage.
Recommended Dosage
| 20°C ‐ 15°C | 1 litre/100 kg cement |
| 15°C ‐ 10°C | 2 litres/100 kg cement |
| 10°C ‐ 5°C | 3 litres/100 kg cement |
