SikaSet® NC-4

Accelerating Admixture

SikaSet® NC-4 is a high performance, non-chloride, water reducing and accelerating admixture. SikaSet® NC-4 meets the requirements of ASTM C-494 Types C and E.

Accelerated Set Times and Strength Development: SikaSet® NC-4 may be used to accelerate set times and increase early strength gain where job-site efficiency is important in order to meet construction deadlines. SikaSet® NC-4 saves time and money by allowing faster finishing and stripping of concrete surfaces.  
  • Predictable accelerated setting time across a wide range of temperatures.
  • Increased early and ultimate compressive and flexural strengths.
  • Reduced insulation and heating costs during the curing period.
  • Accelerated set times allow crews to finish concrete earlier, saving on labor costs.
  • Increased productivity due to faster stripping and reuse of forms.
  • Accelerated strength gain allows earlier structural use and speeds completion time.
    Cold Weather Concreting: In case of freezing conditions, cold weather concreting practices as specified in ACI 306 - Standard Specification for Cold Weather Concreting should be followed.     SikaSet® NC-4 does not contain calcium chloride or any other intentionally added chlorides and will not initiate or promote the corrosion of steel members present in the concrete.
