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
