WINFLOW-GS High Performance AE Water Reducing Agent (Standard Type) KSF 2560

WINFLOW-GS is a liquid type AE water reducing admixture based on naphthalene sulfonate condensate. It improves the quality of high strength concrete by reducing W/C ratio, and also gives good workability. It improves reliability of the concrete structure by reducing effects of construction conditions, and minimize defects such as hydration heat and dry shrinkage.

● USAGE

* Ready mix concrete plant or Batch plant field

* Building, Civil and constructions, and ordinary structures

* High-fluidity and high-strength concrete

* Light weight concrete and concrete structures can be influenced by sea water

* Concrete secondary products

● DOSAGE

* Typical ratios of 0.5% to 2.5% by weight of cement are suggested. Please test concrete to make sure each batch meets the exact specification on site.

* The dosage range is applicable to most concrete mixtures using typical concrete ingredients.

However, variations in job conditions and concrete materials, such as silica fume, may requires

dosages outside the recommended range.

● ADVANTAGES

* Reduces unit weight of cement by high dispersing ability

* Improves workability of concrete

* Hydration heat can be lowered by reduction of cement

● PROPERTIES

* Appearance : Dark brown liquid

* Specific gravity : 1.200±0.05 (20℃)

* pH : 7.0±3.0
