Sika® Stabilizer-821 CS
Colloidal silica-based viscosity modifying admixture
Sika® Stabilizer-821 CS is a colloidal silica-based viscosity modifying admixtures which enhances the stabilty of concrete mixtures.
- Enhances stability of concrete matrix integrity during high slump placements, by reducing segregation and bleeding
- Sika® Stabilizer-821 CS helps stabilise the air void system in fresh concrete
- Improves distribution of aggregate in the concrete mix
- Compatible with Sika ViscoCrete® and SikaPlast® Technology
- Increases the cohesiveness of lean and harsh mixtures
- Decreases pumping pressures
- Improves surface finishability
- Sika® Stabilizer-821 CS reduces shotcrete rebound
