ADMIXTURE FOR CONCRETE CONTAINING AGGREGATES WITH IMPURITIES Sika® Stabilizer-500 VCC is a unique concrete admixture, specially formulated to improve the plastic and hardened properties of concrete containing fine aggregates with Variable Contaminant Content. Sika® Stabilizer-500 VCC can reduce the impact of deleterious substances found in both natural and manufactured sands. Sika® Stabilizer-500 VCC can help control water demands and lower cement contents whilst reducing variation in plastic properties. - Reduces variation in consistence control.
- Improved cohesion properties.
- Improved rheology.
- Reduces the effect of clay contamination.
- Reduces the effect of ultra-fine particles in sand (<63μm)
- Potential to reduce cement contents in problem packages.
- Potential to utilise secondary aggregate sources.
- Improved durability.
- Reduced segregation and bleeding.
- Reduced drying shrinkage.
- Reduced mix costs.

Technical Information Specific Advice Batching procedure is critical to gain the most benefit from Sika® Stabilizer-500 VCC. It must be incorporated early in the mixing process and allowed to adsorb onto the clay/fine particles before the addition of any subsequent admixtures. Addition of the conventional admixture at the same time as the Sika® Stabilizer-500 VCC will lead to reduced benefits.
|
Application Information Dispensing Sika® Stabilizer-500 VCC should be dispensed through suitable calibrated dosing equipment. Compatibility Sika® Stabilizer-500 VCC is compatible with other Sika admixtures and all common cement types. For specific compatibility advice, please contact our Technical Services department. |
