Sika ViscoFlow®-2020


Sika ViscoFlow®-2020 is a workability retaining admixture for use in various concrete applications.

Sika ViscoFlow®-2020 is unique concrete admixture used to improve workability and slump retention of freshly-mixed concrete. Sika ViscoFlow®-2020 contains the latest time-released polycarboxylate polymer technology, allowing for controlled slump extension depending on project needs and actual concreting conditions. Sika ViscoFlow®-2020 typically does not significantly increase slump of the concrete mixture once introduced and properly mixed, but, rather, maintains concrete consistency for an extended period of time, resulting in a “flat” slump life performance. Sika ViscoFlow®-2020 can be successfully used in various concrete applications, specifically whenever extended slump retention and concrete plasticity without set time delays is required. Sika ViscoFlow®-2020 is engineered to maximize product performance and to deliver desired consistency across the wide variety of cementitious materials available on the market. Sika ViscoFlow®-2020 is not a set-retarding admixture.    
Use of Sika ViscoFlow®-2020 offers the following benefits to a concrete producer:
  • Extended slump retention without excessive set retardation
  • Reduced or eliminated need for concrete re-tempering
  • “Flat” slump life performance
  • Better ability to optimize concrete mix designs, resulting in cost savings
  • Ability to use higher content of supplementary cementitious materials due to improved production consistency
  • Ability to adjust the slump retention accordingly to transportation time
  • Easy and simple adjustment of concrete slump-retention based on ambient temperatures
  • Improved concrete consistency and reduced rejection rates due to issues related to concrete re-tempering
