Sika® Stabilizer-600 VCC

Clay And Contaminant Mitigating Admixture For Concrete

Sika® Stabilizer-600 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-600 VCC can reduce the impact of deleterious substances found in both natural and manufactured sands. Sika® Stabilizer-600 VCC can help control water and plasticiser demand and lower cement contents whilst reducing variation in plastic properties.

  • Non Plasticising
  • Reduces variation in consistence control.
  • Improved rheology.
  • Reduces the effect of clay contamination.
  • Reduces the effect of ultra-fine particles in sand (<63 μm)
  • Potential to reduce cement contents in problem packages.
  • Potential to utilise secondary aggregate sources.
  • Improved durability.

Technical Information

Specific Advice

Batching procedure is critical to gain the most benefit from Sika® Stabilizer-600 VCC. Ideally, it should 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-600 VCC may lead to reduced benefits.  Higher dosages may retard early strength development.

Application

Application Information

Dispensing

Sika® Stabilizer-600 VCC should be dispensed through suitable corrosion-resistant, calibrated dosing equipment

Compatibility

Sika® Stabilizer-600 VCC is compatible with other Sika admixtures and all common cement types. For specific compatibility advice, please contact our Technical Services department.
Consumption

Recommended Dosage

Dosage will vary depending upon specific local materials but is expected to be in the range 0.3 to 1.0 % by weight of cement.
Application steps

APPLICATION INSTRUCTIONS

▪ The standard rules of good concreting practice, concerning production and placing, are to be followed.

▪ Laboratory trials shall be carried out before concreting on site, especially when using a new mix design or producing new concrete components.

▪ Fresh concrete must be cured properly and curing applied as soon as possible.
