Description

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 super-plasticizer. 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.


Features and benefits:

  • 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.
