concrete admixtures


Admixtures for ready-mix and precast concrete



HK – II (BV) causes due to the reduction of the surface dension and by electrostatic repulsive forces of the cement particles a liquefaction effect for increasing the consistency or the reduction of the mixing water to increase the compression and bending tensile strength.

Application area

  • For the production of ready-mix-concrete, pumped concrete, exposed and site-mixed concrete in general building construction, excavation, and civil engineering during cold weather conditions.
  • The application of HK-II (BV) is used to improve the characteristics of unset and hardened concrete.
