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.

Naphthalene Sulfonate Formaldehyde Powder Water Reducer


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.

Naphthalene Sulfonate Formaldehyde Powder Water Reducer

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.
