Sika ViscoFlow®-3000 (GB)

High range water reducing/superplasticising concrete admixture with fast adsorption characteristics

Sika ViscoFlow®-3000 (GB) is a liquid admixture for concrete based on unique polycarboxylate polymer technologies. Sika ViscoFlow®-3000 (GB) 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 & densities
  • Improved mixing times
  • Improved cohesion properties
  • Improved early & ultimate strengths
  • Excellent placement characteristics
  • Improved rheology
  • Improved durability
  • Reduced segregation & bleeding
  • Reduced drying shrinkage
  • Reduced mix costs

APPLICATION INSTRUCTIONS

Application Method / Tools

  • The standard rules of good concreting practice, concerning production and placing, are to be followed.
  • Laboratory trials shall be carried out before concreting on site, especially when using a new mix design or producing new concrete components.
  • Fresh concrete must be cured properly and curing applied as soon as possible.

 

Notes on Application / Limitations

When using Sika ViscoFlow®-3000 (GB) a suitable mix design has to be taken into account and local material sources shall be trialled.

  • Sika ViscoFlow®-3000 (GB) shall not be added to dry cement.
  • Excessive water addition or overdosing may cause bleeding or segregation.
  • Support from our Technical Service Department is recommended.
  • Frost: If frozen and / or if precipitation has occurred, Sika ViscoFlow®-3000 (GB) may be used after thawing slowly
