This greatly improves cement dispersion. At the start of the mixing process an electrostatic dispersion occurs but the cement particle’s capacity to separate and disperse. This mechanism considerably reduces the water demand in flowable concrete.
Auramix 400 combines the properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability.
- Low viscosity suitable for pumping of different grades of
- concrete to higher fl oors
- Higher E modulus
- Improved adhesion to reinforcing and prestressing steel
- Better resistance to carbonation
- Lower permeability
- Better resistance to aggressive atmospheric conditions
- Reduced shrinkage and creep
- Increased durability
