Sika ViscoCrete-730 PR

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 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.

Advantages

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.
