Sika® ViscoCrete®-2199

HIGH RANGE WATER-REDUCING ADMIXTURE FOR EARLY STRENGTH CONCRETE

Sika® ViscoCrete®-2199 is a high range water reducing admixture based on selected PCE polymers for promoting high ultimate and early strengths in both ready-mix and precast concrete. Sika® ViscoCrete®-2199 is chloride free according to BS 5075 and is compatible with all types of Portland Cement including Sulphate Resistant Cement (SRC).

As a superplasticiser:
  • Workability is greatly improved
  • Increased placeability in slender components with packed reinforcements
  • Decreases the amount of vibration
  • Suitable for use in conjunction with standard plasticizers and retarders (synergized mixes)
  • Significantly reduces the risk of segregation
  • High early strengths for precast or early stripping
As a water-reducer:
  • Water reduction up to 25 % depending on dosage*
  • 28 days strength improved by up to 40 %*

* this will depend on dosage and mix design
