Naphthalene Sulfonate Water Reducer FDN-A, B

Product Description

Naphthalene series water reducer has the characteristics of high water reduction rate, good fluidity, small slump loss, no segregation, no bleeding and so on.  At the same time, it can greatly improve the fluidity of concrete and the strength of each stage, especially the late strength has obvious enhancement effect, and it is the first choice of high strength concrete, commercial concrete, shock-free concrete, self-leveling grouting material and other products.

Product Characteristics

1. This product is non-toxic, non-combustible, stable in form, and has no corrosion effect on steel bars;  

2, gas content 2.5-4.0%, conducive to pumping construction;  

3, sodium sulfate content ≤18%, low alkali content, will not cause alkali aggregate reaction;  

4, water reduction rate 12-20%, can increase the flow of the mix, concrete slump reached 15-20cm;  60min loss ≤20mm, suitable for continuous pouring of large volume concrete in hot season, reduce hydration heat release, reduce the temperature stress of concrete, avoid the generation of temperature difference cracks;  

5, increase the compactness of concrete, reduce shrinkage, improve the durability of concrete, extend the service life of concrete.
