Naphthalene Superplasticizer Powder Construction Chemicals for Concrete JF-2

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.

Properties

*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.
