WINFLOW-GPS
High Performance AE Water Reducing Agent (Standard Type) KSF 2560
WINFLOW-GPS is a polycarboxylate ether based high performance copolymer designed for highest concrete quality. It enables concrete to be produced highly workable at low dosage with improved slump retention. It can be applicable to ordinary and high performance concrete with high air content retention and minimized setting retardation.
● USAGE
* Ready mix concrete plant or Batch plant field
* High fluidity concrete
* Low heat concrete and shrinkage reduced concrete
* Pre-Cast and Pre-stressed concrete
* SOC project construction of LNG terminal, high-speed rail and tunnel and etc.
● DOSAGE
* Typical ratios of 0.5% to 3.0% 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
* High strength concrete can be produced with high water reducing ability
* High durable concrete can be produced by low alkali and low chloride content in it
* High workability of concrete with improved slump and air content retention
* Hydration heat can be lowered by reduction of cement
* Uniform concrete can be produced with by reducing aggregate segregation
* Prevent delayed construction duration with low setting retardation
● PROPERTIES
* Appearance : Light yellow/brown liquid
* Specific gravity : 1.050±0.05 (20℃)
* pH : 6.5±3.0
