BETONMIX® SP 907 K
BETONMIX® SP 907 K is a naphthalene sulfonate and lignosulfonate-based concrete additive improving early and final concrete strength and fluidity and highly reducing water.
Conforms to EN 934-2, table 3.1.
AZS 221 - 2006
Product code: 207.60011
Application Areas
- In concretes requiring high early and final strength
- In prefabricated and precast concrete
- In dense, hardly spread concretes
- In concrete applications requiring a dense and even surface
- In concrete requiring early demoulding
- In the production of ready-mixed concrete with or without a pump
- In the production of concrete under cold and cool weather conditions
- In dams, bridges, and other decorative concrete structures
Advantages
- Suitable for different types of cement
- Increases the early and final strength of concrete
- Keeps concrete flowing for a long time, improves workability, and ensures easy spreading
- Ensures smooth surfaces
- Increases the frost and heat resistance of concrete
- Ensures easy pumping
- Improves the strain-stress properties of concrete such as shrinkage, tensile strength, and water resistance
- Does not contain chlorine and therefore, does not pose damage to reinforcement steel
