Sika® ViscoFlow® 5109 NS is a specially designed PCE based SuperPlasticizer to achieve a significantly enhanced slump flow retention without additional retardation.
Technical Data Sheet
Sika ViscoFlow 5109 NS
Uses
Sika® ViscoFlow® 5109 NS is especially suitable for concrete mixes with extended workability requirements as well as improved flow characteristics.
Sika® ViscoFlow® 5109 NS is mainly used for the following types of concrete:
- Any concrete hot/cold weather with extended transportation and workability time
- Suitable for a wide range of applications with high or low W/C and /or high or low environment temperatures
- Define the workability time based on project requirements without a negative effect on early strength development
Advantages
Sika® ViscoFlow® 5109 NS produces a more uniformly cohesive high quality free flowing concrete
Sika® ViscoFlow® 5109 NS will result in the following advantages of concrete:
- Improved dispersion properties
- Keeps workability for extended time
- Slump flow retention without additional retardation
- Constant slump flow
- Smooth concrete and concreting operations
- Improved rheology
- Improved strength development
- Reduced drying shrinkage
- Improved durability
