High Range Water Reducer/Superplasticizer

Sika® ViscoCrete®-730 PR is a third generation High Range Water Reducing/SuperPlasticizing admixture for concrete and mortar.

Sika® ViscoCrete®-730 PR as a powerful water reducer acts by through surface adsorption and sterical effects separating the binder particles the following properties are achieved:
  • Poweful water reduction, resulting in high density, high strength and reduced permeability for water etc.
  • Excellent plasticizing effect resulting in improved flowability, placing and compacting behaviour
  • Especially suitable for the production of Self Compacting Concrete (SCC)
  • Vma for SCC may not require. Sika® ViscoCrete®-730 PR will reduce stickiness.
  • Reduces shrinkage 
  • It does not contain chlorides or other ingredients promoting corrosion of steel reinforcement.
