Naphthalene Superplasticizer Powder Construction Chemicals for Concrete JF-2
Description:
Naphtalene superplasticizer is a high range water reducer,it is a kind of concrete admixture, it water reducing rate 25%
Superplasticizer are widely used in building construction ever since the 1930s.
Features and Benefits:
1. Non-toxic, non-irritating and no corrosion to steel bars.
2. High water reducing rate: over 25%.
3. Strengthening ability.
4. Improving concrete durability and impermeability.
Applications
JF- 2 superplasticizer is used in concrete in industrial and civil buildings, hydraulic engineering, transport system,
port engineering, and municipal engineering.
JF-2 superplasticizer is used in ready mix plants and precast concrete plants.
JF-2 superplasticizer is especially for concrete with slump more than 20 cm.
JF-2 superplasticizer can be used in pumping self-compacting concrete, self-leveling grouting materials.
JF-2 superplasticizer is suit for concrete with the requirements of high early strength, low permeability.
JF-2 superplasticizer can be used in concrete curing either in steam or in air.
JF-2 superplasticizer is especially suitable for steam curing concrete products.
*Excellent water reducing ability. JF- 2 can significantly reduce 15% ~30% mixing water in concrete with 0.5%~1.5%
dosage by binder mass.
*Enhance physical and mechanical properties of concrete.
*Improve workability; reduce cement content (15%~20%).
*Excellent compatibility with ordinary cement.
Powder JF-2 can be added in concrete directly with longer mixing time in later admixing method.

*Powder JF-2 is available in 25kg film-lined bags. 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-2 is two year under normal
conditions. If storage has surpassed the time, test must be done to confirm the validity.
