Sika ViscoFlow®-1100 (GB)

HIGH RANGE WATER REDUCING/SUPERPLASTICISING CONCRETE ADMIXTURE

Sika ViscoFlow®-1100 (GB) is a liquid admixture for concrete based on unique polycarboxylate polymers technologies and 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.

  • High range water reductions resulting in higher strengths and densities
  • Extended consistence retention
  • Improved cohesion properties
  • Improved rheology and durability
  • Reduced segregation and bleeding
  • Reduced drying shrinkage
  • Reduced mix costs
