Sika® ViscoCrete®-8550

ULTRA HIGH RANGE WATER REDUCER WITH HARDENING ACCELERATION

Sika® ViscoCrete®-8550 is a 3rd generation polymer based high performance superplasticizer with hardening acceleration effect for concrete.
Sika® ViscoCrete®-8550 meets requrement of ASTM C494 type F.

Sika® ViscoCrete®-8550 combines different modes of actions. By adsorption on the surface of the fines and keeping them apart while the hydration is in progress, Sika® ViscoCrete®-8550 effects the following concrete properties:
  • Extremely high water reduction (enhanced impermeability & strength of concrete produced);
  • Faster development of early strength. Can reduce the time of steam curing process for getting early strength;
  • Workability can be maintained up to 90 minutes (depending on cement type, temperature and mix design);
  • Improved creep and shrinkage resistance characteristics.
