Sika® ViscoCrete®-3270

CONCRETE ADMIXTURE FOR HIGH FLOW / SELF COMPACTING CONCRETE

Sika® ViscoCrete®-3270 is a third generation superplasticiser for concrete and mortar. It is particularly developed for the production of high flow concrete with exceptional flow retention properties and significant reduction in bleeding and segregation.

Sika® ViscoCrete®-3270 acts by surface adsorption on the cement particles producing a sterical separation effect. Concrete produced with Sika® ViscoCrete®-3270 exhibits the following properties:
  • Excellent flowability (resulting in highly reduced placing and compacting efforts).
  • Strong self-compacting behaviour.
  • Extremely high water reduction (resulting in high density and strengths).
  • Improved shrinkage and creep behaviour.
  • Increased carbonation resistance of the concrete.
  • Improved finish.
  • Reduce tendency to bleeding and segregation.
Sika® ViscoCrete®-3270 does not contain chlorides or other ingredients which promotes steel corrosion. Therefore, it may be used without restriction for reinforced and pre-stressed concrete construction. Sika® ViscoCrete®-3270 gives the concrete extended workability and depending on the mix design and the quality of materials used, self-compacting properties can be maintained for more than 1 hour at 30 °C.
