WINFLOW-SM  AE high range water reducer (Standard Type) KSF2560


A standard lignin-based AE water reducer with naphthalene as a major component. It increases the strength of concrete by reducing the unit quantity of concrete and increases durability due to air-entraining admixtures to make dense concrete. In addition, it can be widely used for all concrete structures.



USAGE
* Ready mix concrete plant or Batch plant field
* Concrete secondary products manufacturing plant
* General construction and civil engineering structures
* Concrete roads, runways, and bridges
* Concrete using binders (Fly Ash, Slag Powder)


DOSAGE
* 0.3 ~0.7 wt% of total binder
* For optimal use, it is recommended to mix the actual formulation of concrete on-site in order for supervision to choose the amount of cement based on the strength and workability of the concrete based on site conditions.
* Since air-entrainment is affected by the mixing ratio, concrete materials selection, temperature, and placement methods, the amount used should be adjusted as the concrete is placed.

* Use of excessive amounts may cause problems with the concrete. Thus caution is required.

 

ADVANTAGES
* The amount of cement required is reduced due to the excellent dispersion.
* Increased compressive strength due to a high water reducing ratio of 13%~18%

* Reduction in segregation of materials and concrete bleeding at high slump

* Increased resistance to freezing and thawing due to increased durability and water tightness.

* Excellent concrete properties based on binder substitution  


PROPERTIES
* Appearance  : Dark brown liquid
* Specific gravity : 1.200±0.05 (20℃)
* pH     : 7.0±3.0
* It can be used in parallel with other admixtures.

 

 

Packing : 250kg/drum, Tank Lorry
