Sika® ViscoCrete®-20 HE

High Range Water Reducer / Superplasticiser

Sika® ViscoCrete®-20 HE is a liquid admixture for concrete and mortar which is used as high range water reducer or superplasticiser. Sika® ViscoCrete®-20 HE is designed to work on a combination of electrostatic adsorption and steric repulsion effects allowing solid particles to be effectively dispersed. Therefore a high level of fluidity and plasticising can be reached with a high water reduction which provides many advantages.

  • High water reduction
  • High final density and strength properties
  • Reduced shrinkage, creep, water permeability, etc
  • Improved flowability, placing and compacting
    behaviour
  • Improved surface finish
  • Increased early strength development
  • Early removal of formwork
  • Reduced curing
  • Does not contain chlorides
  • Suitable for use in reinforced and pre-stressed
    concrete
