High range water reducing/superplasticising concrete admixture with enhanced workability retention

Sika ViscoFlow®-1000 is a liquid admixture for concrete based on unique polycarboxylate polymers technologies. Sika ViscoFlow®-1000 is designed as a high range water reducer or superplasticiser. It is particularly suited for use in concretes that require low water/cement ratios and / or high water reductions with excellent workability retention properties of up to 3 hours.
Sika ViscoFlow®-1000 meets the requirements of BS EN 934-2 table.

  • High range water reductions resulting in higher strengths and densities
  • Extended consistence retention
  • Improved cohesion properties
  • Improved early and ultimate strengths
  • Excellent placement characteristics
  • Improved rheology
  • Improved durability
  • Reduced segregation and bleeding
  • Reduced drying shrinkage
  • Reduced mix costs
Usage
Sika ViscoFlow®-1000 is a unique product that is suitable for the production of ready mixed concrete
  • Applications that require extended consistence retention without delayed setting
  • Suitability for use across broad range of consistence classes from S3 – SF3
  • High performance concrete
  • Self compacting concrete
  • High rise/pumped concrete
  • Slip form concrete
  • Improved effectiveness in higher ambient temperatures
