Sika® ViscoCrete®-20 HE

High Range Water Reducer Admixture

Sika® ViscoCrete®-20 HE   is a third generation superplasticiser designed for the production of concrete with high early strength characteristics. The special formulation of Sika® ViscoCrete®-20 HE optimises the dispersion of the binder and at the same time improves the concrete consistency and cohesion.

Sika® ViscoCrete®-20 HE is a high early strength superplasticiser, which through surface absorption and sterical effects, the following properties can be achieved:
  • Promote high density and impermeable concrete through extreme high water reduction.
  • Improves workability and finishability.
  • Improves shrinkage and creep behaviour.
  • Pronounced increase in the early strength development and set times.
  • Higher ultimate strengths.
  • Increases the durability of the concrete.
  • Improved flowability, placing and compacting behaviour,suitable for the production of self compacting concrete.
  • Early removal of formwork.
  • Does not contain chlorides.
  • Suitable for use in reinforced and pre-stressed concrete.
