Slows down the hydration of cement by momentarily blocking the surface of the cement particles. At the end of setting, the concrete hardens rapidly and high compressive strength is obtained after 28 days.
- Has no surface tension effects
- Is use in concrete modifies in no way the consistency of concrete
Domains of application
- All types of cement
- Mass concrete and tiling mortar
- Piles, diaghragm walls
- Pouring of concrete at high temperature
