SikaTell®

Colloidal silica-based Viscosity Modifying Admixture

SikaTell® is a colloidal silica-based admixture that increases mix cohesiveness and the viscosity characteristics of concrete.  SikaTell® produces concrete that becomes fluid and flowable when sheared or mechanically agitated.  This characteristic enables concrete to flow through and into confined spaces.  The mix will revert to a dense, highly viscous consistency when at rest.  This cohesive cement paste matrix promotes high compressive and flexural strength development.

  • Enhances stability of concrete matrix integrity during high slump placements, by reducing segregation and bleeding
  • SikaTell® helps stabilise the air void system in fresh concrete. 
  • Improves distribution of aggregate in the concrete mix
  • Compatible with Sika ViscoCrete® Technology
  • Increases the cohesiveness of lean and harsh mix designs
  • Decreases pumping pressures
  • Improves surface finishability
  • Contains reactive micro particles that improves early age and long term compressive strength
