Sika ViscoCrete-735 PR

Sika® ViscoCrete®-735 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®-735 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®-735 PR as a powerful water reducer acts by through surface adsorption and sterical effects separating the binder particles the following properties are achieved:

• Powerful 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
• Improved shrinkage and creep behaviour
• It does not contain chlorides or other ingredients promoting corrosion of steel reinforcement. It is therefore suitable for reinforced and pre stressed steel
