Sika ViscoFlow-31®

Sika ViscoFlow-31® is a superplasticizer based on polycarboxylate ether for consistency control in ready-mixed concrete.

More about

• Suitable for cements with low effective alkali content (NA) and cements with low water requirements

• Consistency retention without additional delay and without impairing the development of early strength
• Constant consistency and flowability of the concrete

Sika ViscoFlow-31® causes a combined effect of electrostatic adsorption and steric repulsion, while at the same time forming a depot effect. In this way, the solid particles can be effectively distributed in the finest possible way. Compared to conventional polycarboxylate ethers, this means that processing times can be set for longer than 90 minutes in concrete.
