Fosroc Auramix 300 Advanced low viscosity retarding Superplasticiser, based on Polycarboxylic technology

Description
Auramix 300 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 fl owable concrete.Auramix 300 combines the properties of water reduction and workability retention. It allows the production of high performance concrete and/or concrete with high workability. Auramix 300 Auramix 300 is a strong superplasticiser allowing production of consistent concrete properties around the required dosage.

Uses
Auramix 300 is a high performance retarding superplasticiser
intended for applications where retardation and long workability
retention are required, and it has been developed for use in:
 Mass raft foundation,
 Pumped concrete,
 Concrete requiring long workability retention,
 High performance concrete.

Advantages
 Increased retardation controls the heat of hydration and
yields high ultimate strength
Arrest bleeding and segregation due to presence of
 in-built VMA.
 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
