Naphthalene Sulfonate Formaldehyde Powder Water Reducer
Description:
Naphthalene sulfonated formaldehyde is concrete additive.It belongs to superplasticizer of non air entraining agent,It used in
concrete,has a big effect of Water-reducing property,workable performance,augment flow ability of concrete mixture,saving
cement,reducing project cost,It is indispensable component of modern high-efficiency concrete,pumping concrete and
ordinary concrete.
Applications
Impermeability mark of JF-3 can be P12, intensity of 100 times freezing and thawing cycle without loss and
lasting quality has improved significantly.
JF-3 is suitable for continuous concrete in mass in the hot season, reduce the hydration heat
and avoid temperature cracks.
JF-3 can improve the concrete workability and enhance the technical performance of concrete.
To strictly control the content in accordance with the mix ratio of construction, do not exceedthe recommended dosage.
Before JF-3 mixed use with other admixture, it must pass the laboratory test.
JF-3 is chloride – free, low alkali, good for the adaptability of cement and can be used in all kinds of reinforced
concrete engineering.
JF-3 is applicable to concrete construction in the temperature conditions of - 5 ° c - 40 degrees Celsius.
JF-3 isn’t suitable for the cement admixture which is made by anhydrite and fluorgypsum and also
unsuitable for prefabricated part of steam curing.
Properties
Excellent water-reducing ability. JF-3 can significantly reduce 15% ~30% mixing water in concrete
with 0.75%~1.5% dosage.
JF-3 can be cooperated to use with good quality of mineral admixture to make C80 high strength concrete.
Setting time: setting time delay 2-4h.Raise special requirements in the service at pre-sales stage.
