concrete admixtures


Admixtures for ready-mix and precast concrete



SK – I (FM) causes an improved breakdown of the cement matrix by reducing the surface tension of the mixing water. This results in an even homogeneous dispersed cement paste with low internal frictional force which leads to a substantial improvement in workability and the ability of the concrete to densify.

Application area

  • For the production of flow concrete in ready-mix-concrete-and construction site concrete during warm weather with early and high strength characteristics.
  • The application of SK-I (FM) is used to improve the characteristics of unset and hardened concrete.
