Sika® ViscoCrete®-5520 W

Third generation mid-high range superplasticizer, designed for use in the production of winter concrete

Sika® ViscoCrete®-5520 W is a third generation mid-high range superplasticizer for winter concrete and mortar.

Sika® ViscoCrete®-5520 W acts by different mechanisms. Through surface absorption and sterical separation effect on the cement particles, in parallel to the hydration on process, the following properties are obtained:
  • Strong self compacting behaviour, therefore suitable for the production of self compacting concrete (S.C.C)
  • Extremely high water reduction (resulting in high density and strengths)
  • Excellent flowability (resulting in highly reduced placing and compacting efforts)
  • Improved shrinkage and creep behaviour
  • Reduced rate of carbonation of the concrete
Sika® ViscoCrete®-5520 W does not contain chloride or other steel corrosion promoting ingredients. It may therefore be used without any restriction for reinforced and prestressed concrete construction.
