Sika ViscoFlow®-25 ZA
Workability Enhancing admixture
Sika® ViscoFlow® -25 ZA is a workability enhancing admixture for concrete based on Sikas PCE technology. Sika® ViscoFlow® -25 ZA extends the workability time without a negative effect on early strength development.
Sika® ViscoFlow® -25 ZA works based on a combination of electrostatic adsorption and steric repulsion effects. Thus, solid particles can be effectively dispersed and a high level of fluidity can be reached with less water.
As a result, Sika® ViscoFlow® -25 ZA can provide higher workability time and stability than conventional dispersants.
- Compatibility with other additives
- Keeps workability for extended time
- Slump retention without additional retardation and subsequent fast strength development
- Constant slump flow and smoothness of the concrete over hours.
- Improved workability with concrete containing poor quality aggregates
