WINFLOW-SS High performance AE high range water reducer (Standard Type) KSF 2560

WINFLOW-SS is a polycarboxylic acid based high performance AE high range water reducer that uses Polycarboxylic Copolymer and Lignosulfonate as the main ingredients. It maintains high performance and excellent workability of concrete while reducing water when mixing with a massive incorporation of fly ash and slag. By minimizing the loss of slump and air, workability is maintained for an extended time. The product provides concrete with excellent maintainability at the same time as providing better water reducing power than regular AE water reducer.

● USAGE
* General and high performance concrete
* General construction and civil engineering structures
* Lightweight Concrete
* Low heat, low-cracked concrete
* Other concrete products

● DOSAGE
* Typical ratios of 0.3% to 1.5% by weight of cement are suggested. Please test concrete to make sure each batch meets the exact specification on site.

● ADVANTAGES
* The workability of the concrete is excellent.
* Slump loss and loss of entrained air are little so that it is easy to work for a long time due to the excellent staying power.
* Segregation resistance is excellent due to the increase of the concrete paste.

* It has a great effect on reducing the heat of hydration when binders (F / A, S / P) are used.

* Slump retention time and setting time can be adjusted.

* It is excellent to increase in strength and to prevent drying shrinkage cracks due to a reduction in the unit quantity.

● PROPERTIES
* Appearance : Light brown liquid
* Specific gravity : 1.040±0.05 (20℃)
* pH : 7.0±3.0

● Precautions

* It cannot be used with naphthalene interchangeably.

* The best way to store bags of cement is to prevent it to be mixed with other admixtures and foreign matter such as rain from entering.

* Fresh water can be used to wash off any that comes in contact with your skin or clothes.

* Please refer to the Material Safety Data Sheet (MSDS) about other properties and handling instructions.

● Packing : 200kg/drum, 1TON/drum, Tank Lorry
