Description :

Sika® ViscoCrete®-4400 is a liquid admixture for concrete based on a unique blend of polycarboxylate polymers technologies. Sika® ViscoCrete®-4400 is designed as a wokability extender for concrete that require retention properties of over 3 hours.

Uses :

• Applications that require extended and stable consistence
  retention without delayed setting or reduction
  in early age strength
• Suitability for use across broad range of consistence classes from S2 – SF3
• High-performance concrete
• Self-compacting concrete when used in conjunction with an additional superplasticiser
• High-rise/pumped concrete
• Improved effectiveness in higher ambient temperatures

Characteristics/Advantages :

• Extended consistence retention without sacrificing strength development
• Excellent placement characteristics for longer
• Extended travel time/delivery radius
• Limited plasticising effect at lower dosage
• Enhanced workability retention in mixes containing GGBS and PFA
