Main uses

High performance superplasticising and work-ability retention admixture

Uses
Auramix SP211 is a high performance superplasticiser designed for good flow and retention properties in readymix concrete designed to use in:

• Suitable for high slump concrete without bleed and segregation
• Suitable for high rise buildings/longer distance pumping with excellent slump retention properties
• Suitable for high performance concrete containing cement replacement products such as PFA, GGBFS and micro-silica and low water/cement ratio 
• To provide improved durability by increasing ultimate strengths and reducing concrete permeability

Advantages

• Makes possible major reductions in water/cement ratio which allow the production of high performance concrete. 
• Increased workability levels are maintained longer than with ordinary sulphonated melamine admixtures.  Cohesive concrete with reduced stickiness ideal for slabs, columns and longer distance pumping.  Minimises
• bleed and segregation due to variations in grading and moisture content. 
• Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability.  Chloride free, safe for use in pre-stressed and reinforced concrete.
