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
