SikaSet® NC
ACCELERATING ADMIXTURE
SikaSet® NC is a non-chloride, water reducing and accelerating admixture. SikaSet® NC meets the requirements of ASTM C494 Types C and E admixtures.
- Accelerated setting time across a wide range of temperatures
- Increased early and ultimate compressive and flexural strengths
- Insulation and heating costs during curing time are reduced
- Accelerated set times allow crews to finish concrete earlier, saving on labor costs
- Earlier stripping and reuse of forms increases labor productivity
- Accelerated strength gain allows earlier structural use and speeds completion time
Cold Weather Concreting: At the recommended dosage rate SikaSet® NC will protect concrete from freezing in most sub-freezing temperature conditions and may reduce the need for cold weather concreting practices as specified in ACI 306 - Standard Specification for Cold Weather Concreting.
Usage
SikaSet® NC is an effective accelerator where high early strength concrete is desired and the use of calcium chloride is prohibited.Advantages
Accelerated Set Times and Strength Development: SikaSet® NC may be used to accelerate set times and increase early strength gain where jobsite efficiency is important in order to meet construction deadlines. SikaSet® NC saves time and money by allowing faster finishing and stripping of concrete surfaces.- Accelerated setting time across a wide range of temperatures

Application
Mixing
Mixing
Add the correct amount of SikaSet® NC at the concrete plant. The admixture may be added manually or by automated dispenser directly into the sand or into the water line at the batch plant.
Combination with other admixtures:
SikaSet® NC is highly effective as a single admixture or in combination with other Sika® admixtures. Add the correct amount of SikaSet® NC at the concrete plant. The admixture may be added manually or by automated dispenser directly into the sand or into the water line at the batch plant.
Clean Up
Use personal protective equipment (chemical resistant goggles/gloves/clothing). Without direct contact, remove spilled or excess product and place in suitable sealed container. Dispose of excess product and container in accordance with applicable environmental regulations.
Restrictions
- When used in combination with other admixtures care must be taken to dispense each admixture separately into the mix.
- Do not mix with dry cement.
- Field evaluations should be carried out to determine the minimum ambient and concrete temperature required, and the optimum dosage for the desired setting time and strength performance.
- Appropriate, sound curing practices must be followed to protect fresh concrete from excessive heat loss in extreme weather conditions.
Recommended Dosage
To accelerate set times dosage at the rate of 650-2940 mL/100 kg (10-45 fl. oz. per 100 lb) of cementitious material is recommended.
When used to protect concrete from freezing, dosage will vary with different brands of cement and ambient temperatures and higher dosages may be necessary. Sika recommends that trial mixes be performed to determine the most efficient dosage.
Note: SikaSet® NC will accelerate the setting time before loss of concrete heat but is not considered as an anti-freeze.
When using at a rate of 1040 mL/100 kg or more, adjust mixing water accordingly. Dosage rates outside the recommended range may be used where specialized materials such as microsilica are specified, extreme ambient conditions are encountered or unusual project conditions require special consideration. In this case, contact your Sika Canada Technical Sales Representative for further information.
