Auramix 400

Auramix 400 is a unique combination of the latest generation superplasticisers, based on a polycarboxylic ether polymer with long lateral chains. 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.

USES

Auramix 400 is a high performance superplasticiser intended for applications where high water reduction and long workability retention are required, and it has been developed for use in:

  • Pumped concrete,
  • Suitable for early strength.
  • Self-compacting concrete,
  • High performance concrete.
  • Concrete requiring long workability retention

Advantages

  • Higher E modulus
  • Lower permeability
  • Reduced shrinkage and creep
  • Better resistance to carbonation
  • Improved adhesion to reinforcing and prestressing steel
  • Increased durability
  • Better resistance to aggressive atmospheric conditions
  • Arrest bleeding and segregation due to presence of in-built VMA.
  • Increased retardation controls the heat of hydration and yields high ultimate strength
