Sika ViscoFlow®-1005

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

Sika ViscoFlow®-1005 is a liquid admixture for concrete based on the latest generation of polycarboxylate polymer technologies. Sika ViscoFlow®-1005 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.

  • 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
