Retarding Superplasticizier Concrete Admixture on based Naphtalene JF-3
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%
Improving concrete durability and impermeability
Appropriate setting time
Good compatibility with various types of cement
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
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
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.
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.

Powder JF-3 is available in 25kg film-lined bags. Liquid JF-3 is available in sealed plastic or iron tank.
Other special package can also be available according to prior consultation.
Special measures should be taken to ensure entire package. Keep waterproof during transportation.
Dry and well ventilated warehouse is needed for storage. Quality guarantee of JF-1 is three year under
normal conditions. If storage has surpassed the time,test must be done to confirm the validity
