Sika ViscoFlow®-3400 LV

HIGH RANGE WATER REDUCING/SUPERPLASTICISING CONCRETE ADMIXTURE

Sika ViscoFlow®-3400 LV is a liquid admixture for concrete based on unique polycarboxylate polymers. Sika ViscoFlow®-3400 LV 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. The product provides fast adsorption resulting in highly efficient dispersion and potential reduction in mixing time.

  • High range water reductions resulting in higher strengths and densities
  • Improved mixing times
  • 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
