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.

  • Pronounced increase in the early strength development, resulting in very economic stripping times for pre-cast and in situ concrete
  • Extremely powerful water reduction, resulting in high density, high strengths and reduced water permeability etc.
  • Excellent plasticizing effect, resulting in improved flowability placing and compacting behaviour

Usage

Production of concrete mixes which require high early strength development, powerful water reduction and improved flowability.
 
  • Precast concrete
  • Fast-track concrete
  • In situ concrete requiring fast stripping time
  • Self Compacting Concrete (SCC)
