Ekan® FLEX 617

High Range Water Reducing Super Plasticiser
EN 934-2 T 3.1 / T 3.2

  • EKAN®FLEX 617 is a highly effective water-reducing superplasticiser based on naphthalene-sulfonate.

  • Thanks to its special formula, EKAN®FLEX 617 improves the workability and facilitates the placement of concrete. It is suitable for use in conditions where high workability is desired, in situations requiring high early strength, and in precast concrete production.

  • EKAN®FLEX 617 contributes to the water impermeability of concrete by reducing the water/cement ratio.

  • It is recommended not to mix or use EKAN®FLEX 617 with polycarboxylate-based products.
