StenMix® SUPA 215 is a modified polyvinyl acetate-co-maleamide polymer based, high-range water-reducing and set-retarding, high-performance superplasticizing concrete admixture. With its high clay tolerance it is optimized in particular for placing very low slump concrete without loss of workability or segregation. It conforms to the requirements of EN 934-2 Table 11.1 & 11.2 and ASTM C 494/C 494M Type G.
Areas of Use
StenMix® SUPA 215 is used for producing and placing very low slump concrete without loss of workability. Thanks to its high clay tolerance, it maintains its performance in concrete made with aggregates of high or variable clay content.
These two properties make it possible to place quality concrete without loss of workability or segregation, especially in very low-slump applications. Added to ready-mix concrete it provides excellent workability.
Features & Advantages
- Modified polyvinyl acetate-co-maleamide polymer based, high-performance superplasticizer
- Has a high clay tolerance
- Has a set-retarding effect without affecting final strength
- Enables placement of very low slump concrete without loss of workability
- Creates a void-free, smooth-surfaced concrete mass
- Eliminates the risk of segregation and reduces the vibration required
- Reduces the water requirement of concrete by 15-30% at the appropriate dosage
