Sika® ViscoCrete®-730 PR
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)
Usage
Sika® ViscoCrete®-730 PR is specially suitable for the production of concrete mixes which require high strength development, powerful water reduction and excellent flowability Sika® ViscoCrete®-730 PR is mainly used for the following applications:
- Ready mixed concrete
- Precast concrete
- Site batched concrete
- ColumnsSelf Compacting Concrete (SCC)
Packaging
255 Kg HDPE Drum/ Bulk supply

DISPENSING
Sika Viscocrete -730 PR can be added into the mixing water or directly into the concrete mixer after 50 – 70% of the mixing water has been added.
The addition of Sika Viscocrete -730 PR PR to dry aggregate or cement is not recommended.
To achieve optimum performance a minimum wet mixing time, which is depending on the mixing conditions and the mixer performance, of 60 seconds is recommended.
Recommended Dosage
Optimum dosage of Sika® ViscoCrete®-730 PR should be determined by site trials.
Recommended dosage: 0.2 – 2.0% by weight of cementitious.
A higher dosage might be used if agreed by client or consultant.Stir well before use.
