Product Description:


Retarding Superplasticizier  Concrete Admixture on based Naphtalene JF-3


Description:

JF-3 is a naphthalene-based highly effective water reducing admixtures for promoting slump retention type, 

commonly referred to as a superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate

 (NSF), SNF, PNS and FDN etc.

Features and Benefits:

Non-toxic, non-irritating and no corrosion to steel bars

High water reducing rate: up to 25%

Strengthening ability

Improving concrete durability and impermeability

Appropriate setting time

Good compatibility with various types of cement

Retarding Superplasticizier  Concrete Admixture on based Naphtalene JF-3

Applications


  • Impermeability mark of JF- 3 can be P10, 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.

Retarding Superplasticizier  Concrete Admixture on based Naphtalene JF-3

Properties


  • Excellent water-reducing ability. JF -3 can significantly reduce 15% ~30% mixing water in concrete  with 0.75%~1.5% dosage for powder, 1.5-3.0%.for liquid.

  • JF-3 can be cooperated to use with good quality of mineral admixture to make C80 high strength concrete.

  • When the strength of concrete and slump constant are basically the same with the base concrete,

    JF-3 can reduce cement content (15%~20%).

  • Retention value of slump constant: 1h>90%   2h>85%。

  • Setting time: setting time delay 2-5h.Raise special requirements in the service at pre-sales stage.
