Auramix 300 Retarder Admixture For Concrete

About Auramix 300 Retarder Admixture For Concrete

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 particles 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 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

         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
