Sika® ViscoCrete®-203 SC


Sika® ViscoCrete®-203 SC is a third generation superplasticiser for concrete and mortar with enhanced workability retention. It meets the requirements
for high range water reducing admixture (HWR) according to AS1478.1-2000.

Sika® ViscoCrete®-203 SC is an effective, user friendly superplasticiser which acts through several different mechanisms including
surface adsorption and sterical effects separating the cementitious binder particles.
The following advantageous properties are achieved:
  • High water reduction, resulting in high density, high strength and reduced permeability
  • Extended slump life to meet the needs of tunnelling and mining shotcrete
  • Superior plasticising effect, resulting in improved flow, placing and compaction characteristics
  • Reduced shrinkage during curing and reduced creep when hardened
  • Sika® ViscoCrete®-203 SC does not contain chlorides or any other ingredients which promote the corrosion of steel. It is therefore suitable for use in reinforced and pre-stressed concrete structures
