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
