The construction industry with the various challenging projects is demanding more and more workability time of the fresh concrete, in order to be as flexible as possible. On the other hand the initial setting time of the concrete shouldn’t be influenced in a negative way. The solution for this demand is our newest technology Sika ViscoFlow.

Additional workability time

The key element of Sika ViscoFlow is a brand new developed PCE, enhancing the workability time significantly, allowing for the time needed to transport and to place the concrete properly. The initial setting of the concrete is thereby only extended by the additional workability time gained by the use of the new polymer. The workability time can thus be defined based on the requirements:

  • Slump retention without additional retardation and subsequent fast strength development  
  • Constant slump flow and consistency of your concrete for hours
  • Suitable for a wide range of applications with high or low water/cement ratio and/or high or low ambient temperatures

A polymer fulfilling challenging requirements

Sika ViscoFlow is not only a new admixture, it represents a valuable addition to our polymer toolbox, broadening the range of applications and fulfilling challenging customer requirements.

  • In any concrete Sika ViscoFlow can be used for high performance slump retention facilitating an ensured target. This effect can be achieved without any additional retardation of the initial setting. 
  • The workability can also be ensured when critical cements are used which lead to early stiffening with normal PCE’s.
  • The extended workability time of high performance concrete with a low water /cement ratio and therefore high durability properties can also be set with Sika ViscoFlow. 
  • Under different environmental circumstances such as hot temperatures, the required workability time can be achieved with Sika ViscoFlow.
